Open APIs

Hello everyone,

I am working on a use case where I need to query, based on a government-issued identifier (such as CURP, DNI, SSN, etc.), which MSISDNs (mobile line numbers) are associated with that identifier.

Important: The information I need to query is not stored in customer systems, nor necessarily in systems compatible with the TM Forum Open APIs framework-it resides in an external storage system or a different data repository.

Given this context, which TM Forum Open API(s) would you recommend to enable this type of query, or what approach would you suggest to integrate this functionality while adhering to TM Forum standards and best practices?

I would appreciate any examples, endpoint recommendations, or prior experiences you can share.

Thank you in advance for your assistance!
