Understanding security approaches in SAP CAP using XSUAA in node.js flavor and MTA.
The long version, from the MTA project outward: what the deployment descriptor has to contain, how the authentication flow actually runs, and then the npm modules doing the work — @sap/xssec@sap/xssecToken validation and security context for XSUAA and IAS.sap official, cap and @sap/xsenv named and explained rather than left as dependencies. Old, and the module names have moved on, but the flow it draws has not.

SAP Just Became AI-Agent Ready — Here's a Step-by-Step MCP WalkthroughSAP Just Became AI-Agent Ready — Here's a Step-by-Step MCP WalkthroughBuilds an MCP Server on SAP Integration Suite's Integration Cell, in front of a Cloud Integration flow that passes an OData V4 backend through untouched, with three tools generated from an OpenAPI spec. Secures it with OAuth 2.0 on SAP BTP client_credentials against XSUAA, and walks through the scope mismatch — the service key issues ESBMessaging.send, not the server's default API.invoke — that returns 403 until corrected; the finished server is then registered as a tool in Claude Code.published 2026-09-04
Named-User Attribution Across BTP Subaccounts: A Two-Hop IAS Token Exchange for Cloud IntegrationNamed-User Attribution Across BTP Subaccounts: A Two-Hop IAS Token Exchange for Cloud IntegrationA central BTP application that manages Cloud Integration across subaccounts with client_credentials collapses every user into one technical service principal: target subaccounts' role collections are bypassed and the audit log names a service key instead of a person. The post works through a two-hop exchange — an IAS app-to-app hop, then the target subaccount's XSUAA jwt-bearer hop — that carries the calling user's own identity across the subaccount boundary through a shared Cloud Identity Services tenant, so the target subaccount enforces the user's own role collection and records their identity in the audit log. It walks through the IAS app-dependency setup, the AppRouter and SAP Destination service configuration the exchange needs, and states the pattern applies to any XSUAA-protected service in a separate subaccount, not only Cloud Integration.agnissh, published 2026-08-24
Connecting a Custom MCP Server to Joule Work Desktop: A Seamless and Secure Authentication FlowConnecting a Custom MCP Server to Joule Work Desktop: A Seamless and Secure Authentication FlowWalks through connecting a custom MCP server to Joule Work Desktop: a Dynamic Client Registration handshake (RFC 7591) followed by an Authorization Code + PKCE flow through the organisation's SSO via XSUAA or IAS, so authentication establishes the human identity that Joule then attaches to every subsequent tool call. That forwarded identity lets the BTP backend apply its existing authorization checks and row-level data filtering instead of a second permission model, and a role change in XSUAA revokes access on the next token refresh.published 2026-08-17
Securing a CAP Node.js App with SAP AMS on BTP Cloud FoundrySecuring a CAP Node.js App with SAP AMS on BTP Cloud FoundryThe end-to-end version: a CAP Node.js project from cds init, role-based access through the Authorization Management Service and Identity Authentication Service, and an MTA deployment to Cloud Foundry.

Principal Propagation from BTP Web App to S/4HANA via SAP Integration SuitePrincipal Propagation from BTP Web App to S/4HANA via SAP Integration SuiteWalks through configuring principal propagation from a BTP web app, through SAP Integration Suite and Cloud Connector, to an on-premise S/4HANA system, so the backend receives calls as the logged-in user rather than a shared service account. The BTP Destination service uses OAuth2JWTBearer to exchange the user's Cloud Identity Services JWT for an Integration Suite token, and the iFlow's OData V2 receiver adapter reaches S/4HANA through Cloud Connector with Principal Propagation authentication. The Cloud Connector Subject Pattern builds the outbound certificate's CN from the token's user_name claim, which is populated from the IAS email rather than the sub claim, so identity resolution on S/4HANA hinges on that email matching a resolvable logon name.Joni, published 2026-07-10
Effective from June 30th 2026 - XSUAA Deprecation of GET Method for OAuth Token RetrievalEffective from June 30th 2026 - XSUAA Deprecation of GET Method for OAuth Token RetrievalEffective June 30th 2026, the SAP Authorization and Trust Management service (XSUAA) deprecates the HTTP GET method for retrieving an OAuth access token from its /oauth/token endpoint, leaving only POST supported in line with RFC 6749. A client still requesting a token via GET with grant_type and credentials in the query string stops working after the cutover and must switch to a POST request with form-encoded body parameters.Yogananda, published 2026-06-14
From XSUAA to AMS: Architecting S4HANA CAP Extensions with Policy-Based AuthorizationFrom XSUAA to AMS: Architecting S4HANA CAP Extensions with Policy-Based AuthorizationWhy scope-based authorization runs out, argued from enterprise extension work rather than from the documentation: XSUAA handles roles well, but real requirements are business-context restrictions — country, company code, organisational unit — and expressing those as scopes does not scale. The migration to policy-based authorization is presented as an architectural move for S/4HANA extensions rather than a configuration change.Avinash Vaidya, published 2026-05-27

Dynamic authorisation with user attributes in SAP CAP and AMSDynamic authorisation with user attributes in SAP CAP and AMSThe same argument as the XSUAA-to-AMS piece, opened from a concrete failure: an acquisition puts 500 users on sales data restricted by division, and role-based access control answers it with Sales_Manager_EMEA, Sales_Manager_APAC and so on until the roles multiply past managing. Attribute-based authorisation replaces the set with one policy carrying a restriction, and the post walks through defining it in AMS against Cloud Identity Services. The clearest statement of role explosion among the three AMS pieces here.pedro_iranzo, published 2026-05-04
Agentic AI on BTP: a Single Agent with LangGraphAgentic AI on BTP: a Single Agent with LangGraphA CAP TypeScript agent puts a LangGraph StateGraph in front of AzureOpenAiChatClient from @sap-ai-sdk/langchain, reaching SAP AI Core's Generative AI Hub, and lets its tool-calling loop draw on five deployed MCP servers — OData MCP Proxy, CI MCP Server, AI Core MCP Server, BTP MCP Server and BTP CF MCP Server — through @langchain/mcp-adapters' MultiServerMCPClient. Because agent, servers and APIs share one XSUAA tenant, the chat service forwards the signed-in user's own JWT instead of a service account, so each downstream server enforces that user's own authorizations. Past roughly a hundred combined tools the single prompt slows down and stops separating concerns, which is why the author's next post splits it into one specialist agent per MCP server behind an orchestrator.published 2026-05-03
Standardized OIDC API Access to SAP S/4HANA via SAP API Management and Microsoft Entra IDStandardized OIDC API Access to SAP S/4HANA via SAP API Management and Microsoft Entra IDSAP API Management exchanges a Microsoft Entra ID access token for one issued by Cloud Identity Services, using an RFC 7523 JWT Bearer Token Exchange so an Azure service principal never holds S/4HANA credentials. SAP S/4HANA then validates that IAS token and resolves its claims to a single ABAP user before authorizing the call, which is the boundary authentication draws on BTP: the identity behind the token, not what it is then allowed to do.StigPraefcke, published 2026-04-29
Standardized OIDC API Access to SAP SuccessFactors via SAP API Management and Microsoft Entra IDStandardized OIDC API Access to SAP SuccessFactors via SAP API Management and Microsoft Entra IDAPI Management in SAP Integration Suite is the pattern's enforcement point: it intercepts a Microsoft Entra ID access token from a service principal and exchanges it, via the OAuth 2.0 JWT Bearer Token Exchange grant (RFC 7523), for a token issued by Cloud Identity Services, with Entra ID configured as a trusted corporate identity provider inside IAS. SAP SuccessFactors accepts only IAS-issued tokens, per SAP Note 3681224, so the exchange happens once at the gateway and client applications never hold SAP-specific credentials.StigPraefcke, published 2026-04-13
Integrating and Extending JouleIntegrating and Extending JouleSAP's reference architecture for SAP Joule across SAP cloud applications: a request is checked against a Scenario Catalog of the applications' skills and a Knowledge Catalog answered by retrieval-augmented generation, combined with the user's roles and history, sent to an LLM available through the generative AI hub, and, where a Joule function is needed, turned into a call to the backend. Its identity page is the authentication path: each user sits in the Identity Directory of Cloud Identity Services with a Global User ID, Identity Provisioning synchronises role assignments into SAP Build Work Zone, whose navigation service decides which functions a user may call, and the Destination service exchanges the user's token to call a function in the user's name. Its extension page covers Joule Studio in SAP Build, where Joule skills automate rule-based tasks over APIs and AI agents plan and reason with models and document grounding from SAP AI Core, the ground agent tooling covers; a later Joule Studio page describes a managed Joule Studio Runtime on the SAP Business AI Platform, which has no entry here.published 2026-03-16
SAP BTP Platform Technical User for CTMS IntegrationSAP BTP Platform Technical User for CTMS IntegrationWalks through creating a technical user in Cloud Identity Services (IAS) as a custom identity provider, adding it to a subaccount's org, space and role collections, and switching a Destinations entry's authentication to OAuth2Password with the Cloud Foundry login endpoint as token service URL and an origin property naming the custom IDP. The technical user lets CI/CD pipelines, API calls and transport automation authenticate without human credentials, keeping service accounts separate from people for audit and access control.Marudhu999, published 2026-03-09

SAP Joule implementation in an S/4HANA private cloud 3 system landscapeSAP Joule implementation in an S/4HANA private cloud 3 system landscapeWalks through enabling SAP Joule across a three-system S/4HANA Private Cloud landscape (DEV, QAS, PRD) rather than the common single-system setup: separate BTP subaccounts for the non-production systems, a shared Cloud Identity Services tenant, and catalogs and roles transported from DEV through QAS to PRD. Covers single sign-on for Joule by setting Microsoft Entra ID as the corporate identity provider in SAP IAS, so authentication flows through Entra ID without the user existing in the IAS store, plus principal propagation through the Cloud Connector into the production backend.Arunrajj, published 2026-01-21
How to Access SAP Cloud Logging Service Dashboards Using IAS SAML AuthenticationHow to Access SAP Cloud Logging Service Dashboards Using IAS SAML AuthenticationWalks through wiring SAML 2.0 single sign-on between SAP Cloud Identity Services (IAS) and SAP Cloud Logging so its OpenSearch dashboards accept IAS logins instead of a service key: creating the SAML application in IAS, editing the instance's saml parameters (admin_group, idp.metadata_url, idp.entity_id, sp.entity_id), setting the matching entity ID and endpoints on the IAS side, and mapping an IAS group to the all_access role through a groups attribute. It also shows how to read a 403 on the dashboard as SAML login succeeding while the group-to-role mapping is still missing.Umezuki, published 2025-12-30

Authorization management with OpenSearch's Document Level Security - SAP Cloud LoggingAuthorization management with OpenSearch's Document Level Security - SAP Cloud LoggingWhere the predecessor SAP Application Logging service reused CF space permissions for read-only access, SAP Cloud Logging integrates with SAP Cloud Identity Services (IAS) and controls per-document visibility through OpenSearch's Document Level Security: an IAS group becomes a backend role, mapped to an OpenSearch role that carries a DLS query filter, so a search request only ever returns documents whose indexed field (space_name, organization_id, or another keyword field) matches what that role's filter allows. It walks through fixed per-space roles, a shared multi-space role using a terms query, and a single dynamic role that substitutes ${user.roles} into the filter so the match is against the caller's own groups, then lists operational pitfalls — wildcard index patterns breaking Dashboards, DLS roles that also hold write access creating log entries nobody can read back, and match queries against a .keyword field being non-deterministic where term queries are exact.Hariharan-Gandhi, published 2025-11-24

Guide to Process Automation APIs - Part I - Getting StartedGuide to Process Automation APIs - Part I - Getting StartedExplains how to call SAP Build Process Automation's REST and OData APIs directly: OAuth2 client credentials with a service key runs as the service, while a user token (OAuth2JWTBearer) runs as the calling person, which matters wherever an API records who acted — approving a task, or reading instances from a shared environment.

Making the Case for Enhanced REST Adapter in SAP Integration SuiteMaking the Case for Enhanced REST Adapter in SAP Integration SuiteCatalogues what SAP Integration Suite's native HTTP adapter supports for authentication (Basic, OAuth 2.0 client credentials and client certificates on the sender; OAuth 2.0 client credentials and SAML bearer assertion on the receiver) and for error handling (retry on HTTP failure only, with no pattern-based retry, failure queues or dead-letter queues), and that it has no OpenAPI import or export. Three worked scenarios, FedEx shipment tracking, Avalara AvaTax and SAP Ariba's operational reporting API, name what that leaves to Groovy scripting: the other OAuth 2.0 flows, gzip and multipart payloads, and pagination that chains a nextPageToken by JSONPath, which is the case the piece makes for the third-party Advantco REST Adapter.peter_ha3, published 2025-07-14
Secure Service Consumption Across HyperscalersSecure Service Consumption Across HyperscalersSAP's design for a workload on SAP BTP that calls Amazon Web Services or Google Cloud services with short-lived credentials instead of stored keys, which is the outbound side of authentication: the BTP application proving who it is to another cloud. On AWS it draws two paths, an ID token from Identity Authentication in Cloud Identity Services exchanged through AWS STS for an IAM role, or an X.509 certificate kept in SAP Destination service and presented to IAM Roles Anywhere; on Google Cloud only the token path, through Workload Identity Federation and an impersonated service account. It is drawn for those two hyperscalers only, and Microsoft Azure has no page in it.published 2025-05-14

CAP for nodejs安全的暴露接口练习CAP for nodejs安全的暴露接口练习Starting from the risk-management sample, the walkthrough adds an open ExternalAPI service beside the existing RiskService, then moves every security annotation into a separate service-auth.cds file: @requires: authenticated-user on one entity, role-scoped @restrict grants for RiskViewer and RiskManager on another. It tests the unprotected action locally with cds watch, calling it from Postman with the session cookie read out of SAP Business Application Studio's preview tab. It then deploys to BTP and reads Risks with a client-credentials OAuth token fetched from a service key of the cpapp-auth instance, after changing that entity's READ grant from RiskViewer to authenticated-user, which the post, citing capire's CDS-based Authorization page, describes as a grant for a technical user integrating systems rather than for access from a front end.ArthurYang, published 2024-12-10
Why SAP Cloud Identity Matters for SAP Task Center: It’s About Trust and Global User IDWhy SAP Cloud Identity Matters for SAP Task Center: It’s About Trust and Global User IDA step-by-step configuration walkthrough for wiring SAP Cloud Identity Services as the trust and user-correlation layer behind SAP Task Center: establishing Identity Authentication as the sole trusted identity provider for the BTP subaccount, and generating the Global User ID — carried in the token's user_uuid claim rather than the SAML name identifier — that Task Center uses to match logged-in users to their tasks.

An approach to secure multiple integrated SAP CAP java applications with a common XSUAA service instanceAn approach to secure multiple integrated SAP CAP java applications with a common XSUAA service instanceOne XSUAA instance across several CAP Java applications that call each other, rather than one per application. Short, and written from inside SAP Labs as something the author tried — the value is the shape of the arrangement, not a walkthrough.sreanik_dhanyakumar2, published 2022-09-14
SAP Business Technology Platform: Authorization and Trust Management ServiceSAP Business Technology Platform: Authorization and Trust Management ServiceWalks through how the SAP Authorization and Trust Management service secures a BTP application: scopes, attributes and role templates in the security descriptor, and the OAuth 2.0 resource-owner, client and resource-server roles it builds on. Covers the XSUAA microservice as the OAuth 2.0 authorization server bound to each application through its service broker, the signed JSON Web Token it issues after authentication, and the App Router's place in front of the resource apps as the gateway that starts authentication and checks for cross-site request forgery.SekhuteTK, published 2022-09-09
How to get authenticated user information with CAP in three different ways – Using the XSUAA APIHow to get authenticated user information with CAP in three different ways – Using the XSUAA APIThe third of three approaches the author sets out, and the one that returns the most: going to the XSUAA API directly rather than reading what CAP already put on the request. Depends on an earlier post for the project setup, so it starts mid-stream on purpose.ale_biagi, published 2022-07-18
Why developers should care about credential-types for xsuaa?Why developers should care about credential-types for xsuaa?Rotating secrets, argued from a habit rather than a feature: the author names the practice implicit in many beginner tutorials — lifting a secret out of a binding to use it elsewhere — and notes CAP has features that make it unnecessary in development. Then the three credential types side by side, configured on a CAP application's uaa resource in mta.yaml and through a deployment extension.former_member2839, published 2022-07-05

Execute [OAuth2 client credentials] protected REST request with SAP CAP ApplicationExecute [OAuth2 client credentials] protected REST request with SAP CAP ApplicationA recipe, and the author calls it that — package.json, a .cds and a handler — for calling a remote service protected by OAuth2 client credentials from a CAP application. Short, complete, and addressed to CAP developers rather than to BTP administrators.Lachmish, published 2022-04-27

Insights of Cloud SDK, CAP, XSUAA, SSH and other BTP topics from 2021Insights of Cloud SDK, CAP, XSUAA, SSH and other BTP topics from 2021A year in review, and one section in it is the reason it is here: "CAP isn't the solution for everything" — the author's point being that a pure UI5 or Fiori application does not need a CAP service wrapped around it, and that an approuter or the HTML5 Application Repository may be the better answer. The XSUAA section is a complaint about complexity rather than a guide, which is also worth having on the record.dr_vup, published 2021-12-30
Using Postman for API Testing with XSUAAUsing Postman for API Testing with XSUAAA way to get a JWT without routing traffic through the approuter and picking the token out of it. The author walks the alternatives first — redirect through the router, intercept the token — and says what is wrong with each, before requesting the token from the service directly.mariusobert, published 2020-03-02
How SAP secures enterprise AI agents with identity propagationHow SAP secures enterprise AI agents with identity propagationCloud Identity Services as the identity layer for AI agents as well as people: the abstract states that both are managed in one directory, that user context is propagated by token exchange, and that authorisation is enforced at every hop, so no agent holds back-end credentials. Agents from Microsoft, Google and partners take the same flow through the agent gateway. Token exchange across a hop is the authentication side and the per-hop check the authorisation side; what the agent gateway is, and whether it is a product, the abstract does not say. A TechEd 2026 session (Wednesday 28 October, Berlin), presented by Gunnar Kosche and Sebastian Ries, written here from SAP's abstract; the recording is not yet published.
Evolving the identity lifecycle for an AI-first futureEvolving the identity lifecycle for an AI-first futureCloud Identity Services as the foundation for authentication, identity lifecycle management and access across SAP landscapes, and the agent identity concepts and SAP-managed identity and access management scenarios SAP says reduce operational effort. The edges are to the service and to the two concerns the abstract names it for, Authentication and Identity provisioning; the abstract names the agent identity concepts and does not say what they are. A TechEd 2026 session (Tuesday 27 October, Berlin), presented by Sonia Petrescu and Swetta Singh, written here from SAP's abstract; the recording is not yet published.
