Backend Developers and System Architects
Designing a new microservice that requires customer identity resolution across multiple systems of record
The UtilityApis mind map template provides a technical architecture overview of essential backend services, covering 5 major utility endpoints and 109 total nodes. This UtilityApis cheat sheet is designed for software engineers and API architects to streamline the integration of identity and account management tools. The map details critical functions such as Tools-ReferenceIds, which handles customer relationship mapping via ECID, and Tools-AccountNumber, which resolves sensitive account data into sorId formats. By centralizing documentation links for Github and Exchange alongside request/response schemas, this UtilityApis template acts as a living technical specification. It specifically addresses complex logic like the TSYS primary card holder lookup and multi-SOR limitations for retail and 360 systems, ensuring developers can anticipate error states when an account-ref-id links to multiple customers.

Troubleshooting integration errors where account-ref-id lookups are failing for non-card SORs
Documenting internal utility endpoints for a centralized developer portal or wiki
Open the .xmind file in Xmind to view the hierarchical breakdown of the five core utility endpoints.
Replace the placeholder Github and Exchange nodes with your team's specific repository URLs and internal wiki pages.
Modify the Request and Response branches to reflect your unique A2PK, A3PK, or ECID parameter requirements.
This template covers five primary utility tools: Tools-ReferenceIds, Tools-RelatedReferenceId, Tools-CustomerRelationshipsId, Tools-ProfileReferenceIds, and Tools-AccountNumber. Each section includes documentation links, request/response structures, and functional summaries.
The template includes specific logic for TSYS lookups to find primary card holders. It also notes limitations for SORs like Retail and 360, specifically detailing how the API handles accounts linked to multiple customers.
Yes, it is an ideal onboarding resource. It visualizes the relationship between request parameters like ECID and the resulting CRID or PRID outputs, making complex backend logic easier to digest than standard text docs.
Absolutely. You can open this template in Xmind and modify the request/response nodes to match your specific environment, or update the Github and Exchange links to point to your internal repositories.
