Online integration

Important

Prepare client credentials available in the user account or from the internal administrator.

Steps to integrate:

1. Firstly, using the client’s credentials, the server must obtain an access token by communicating with the identity server.

Note

The token also contains information about its expiration.

2. Using the received access token, send the document file for prediction.

For integration examples across various programming languages, please visit our Github.
