Here are the steps to follow to check upload results after you send
Customer Match audience members.

## Check request status and diagnostics

Use the `requestId` returned in each successful ingestion response to
[check request status and diagnostics](https://developers.google.com/data-manager/api/devguides/diagnostics). The status
and diagnostics for each request tell you:

- If the Data Manager API has finished processing the request.
- If the Data Manager API identified any issues while processing audience member data in the request.

Fix any issues identified during processing and resubmit the affected audience
members, then check the status and diagnostics again. Repeat this process until
you've resolved as many of the issues as possible.

## Retrieve the updated audience information

Once the status indicates that your requests have been processed, check the
overall state of the audience by retrieving the updated `UserList`.


If the uploads contain contact information, check the `matchRatePercentage` in
the
[`contactIdInfo`](https://developers.google.com/data-manager/api/reference/rest/v1/accountTypes.accounts.userLists#contactidinfo)
field to get the overall match rate for the audience.
