Get OAuth Access Token for Document Information Extraction via Web Browser

To get your OAuth access token you will need the values highlighted in the image below from the service key you created in the previous tutorial: Use Trial to Set Up Account for Document Information Extraction and Get Service Key or Use Free Tier to Set Up Account for Document Information Extraction and Get Service Key.

1. Add /oauth/token?grant_type=client_credentials to the url value (from inside the uaa section of the service key), paste it in any web browser and choose Enter.

2. Enter the clientid value from your service key as Username.

3. Enter the clientsecret value from your service key as Password.

4. Click Sign in or OK (depending on the web browser you work with).

You should receive a response like the following:

{
    "access_token": "<< your access token >>",
    "token_type": "bearer",
    "expires_in": 43199,
    "scope": "<< granted access >>",
    "jti": "<< unique identifier >>"
}

Once the token has been generated, make sure to copy and save it locally for easy access. The token is valid for 12 hours (43199 seconds). After that, you’ll need to generate a new one.

You have successfully generated your OAuth access token for the service and you are now all set to Use Machine Learning to Extract Information from Documents with Swagger UI.
