All DocuPost APIs utilize an API token as means of authentication. Do not provide your token to an untrusted user or application.

To get started, generate an API token here.  

Once you have your API token, you may use it to send requests to our API endpoints.  If your token ever becomes compromised, you may revoke or re-generate a token from your Developer page.

Currently, DocuPost has two API endpoints:

At this time, we do not have a public API for sending checks. If you are in need of this functionality, please reach out to us with information about your use case.
