    Hello,

    I am working on 3CX integration with Zendesk. We are using client-side integration, since it is more convenient for our agents to have tickets automatically updated after phone call.
    We have 2 Zendesk instances - Sandbox and Production.
    I have prepared integration according to tutorial on both instances:
    Code:
    https://www.3cx.com/user-manual/zendesk-crm-integration/ - document no longer exists
    Problem is following:
    When I am trying to log in in Production environment, I receive following error: production-error.PNG

    When I am logging in Sandbox environment using add-in, it works:
    sandbox-success.PNG

    Zendesk support told me that problem is related to 3CX add-in, not instance.
    OAuth authorization is configured correctly, account credentials are correct.

    How to fix this login problem? Please help me.

    Hello,

    Solution was simple.
    Our company is using SSO, but OAuth uses Zendesk's internal passwords. If users don't have such passwords, authorization will fail with 'invalid_grant' error.
    After creating internal Zendesk password (for example, by resetting password), and using it for login, I have logged in successfully.

    Maybe it will help someone :)
