Could you confirm if Azure FHIR Server supports the _offset search param for Claim? If not, can it be enabled or planned?

@Rahul Ranjan ,

You're correct — the Azure API for FHIR does not support the _offset search parameter, including for the Claim resource. This is by design. Instead, Azure FHIR Server uses continuation tokens to handle pagination. These tokens are returned in the Bundle.link with relation="next" when more results are available beyond the initial query.

There’s currently no way to enable _offset, and as of now, there is no announcement to support it.

Recommended Approach — Continuation Token Pagination:

Initial Request: Use _count to define how many results you want per page (up to 1000).

Token-based Pagination: If more data is available, the server responds with a link of relation="next" containing the continuation token.

Subsequent Pages: Use the next URL directly for the next batch of results.

Repeat until there is no next link.

This method is preferred because it provides consistent results even in dynamic datasets, unlike offset-based methods which can miss or duplicate records if data changes between queries.
