Retrieving data from Dataverse is usually the first step in an integration. This guide explains the setup and the limitations you are likely to encounter first.
The integration should have its own identity rather than borrowing someone else's. That way, it will continue to work when someone changes jobs, and its permissions can be limited to only what it actually needs.
The application must exist as a user in the environment and be assigned a security role. This step is often overlooked, and the symptom is that authentication succeeds while all queries return empty results.
The application authenticates with Entra ID and receives a token that is included with every call. The token has a limited lifetime and must be renewed—build this in from the start.
Fetch a few rows from a single table and confirm that you get a response. That way, you know that access and authentication are working before you build anything more.
Without limiting the selection, all columns are returned. This is slow and unnecessary, and the impact is immediately noticeable on large tables.
Large result sets are returned in pages with a link to the next page. An integration that does not follow that link will silently retrieve only the first page—an error that can go unnoticed for a long time.
There are limits per unit of time. Build in pauses and retries when requests are rejected, rather than letting the integration stop completely.
