Implementing monitoring tools or processes to keep track of your application’s usage of the Finch APIs will help you identify patterns and potential issues (see Mitigate Errors for more details). Events such as frequent rate limit overages or a sudden increases in error rates can be quickly identified and actioned if proper monitoring is in place.

​
Use the Introspect Endpoint

The /introspect endpoint is an extremely important tool when using Finch, allowing you to read account information associated with an access_token such as the connection status.

​
Log finch request id

It is best practice to log the finch-request-id for every response, whether successful or unsuccessful. The finch-request-id can be found in every HTTP response Header. The finch-request-id is required by the Finch Support team for debugging request issues.

​
Store the connection id

Each Finch access_token is associated with a static Finch connection_id. You can find the id using the /introspect endpoint. Save this in your data store alongside the access token and use it when contacting Finch Support about an issue.

​
Monitor API requests

Track API response times to and from Finch. A spike in latency can indicate network problems or possible Finch performance degradations. Continuously check for increases in error rate responses from Finch. This can indicate problems with the Finch APIs or issues with how your application sends requests to the Finch APIs.
Finch reports all API outages and provider integration incidents. You can subscribe to receive email notifications from https://status.tryfinch.com whenever we create, update, or resolve an incident.

​
Optimize API usage

Regularly review your application’s usage of Finch APIs and identify opportunities to optimize and improve performance. This may include refining batch request sizes to improve latency, improving error handling, or adjusting request patterns to avoid rate limits.

​
Checkpoint + Next Step

After completing this step, you should be equipped to preemptively identify and address potential issues in your application and your Finch integration, helping you get the most value from Finch’s services. Now that you have an application that is connected, secure, please review the Control Access and Manage Connections guides to make sure your application is set up to handle your specific use case.
