Kariz uses an access token to control access to our API via OAuth 2.0 Password Grant. Use this endpoint to retrieve an access token.

 You will need valid user and application credentials. If you do not have an account, [schedule a demo]([https://cal.com/kariz-pepijn/intro-unified-api]) to gain access. Use this token in the Authorization header of subsequent calls.

Obtain Access Token

Use Magic Links to invite users to connect their accounts. Generate a URL and share it with the end user. 
Once they finish authenticating via the Magic Link, you’ll have a valid token to perform API requests. 
We also support token authentication, reach out to us for more information on this.
