You can add a new integration via the Clickatell Portal, under Products & Services -> Integrations. Ensure you have the relevant information ready beforehand - some of the information is retrieved from the 3rd-party app.

You can add as many sandbox or production configurations as you wish, but note that you cannot promote a sandbox configuration into production. You'll have to create a separate production configuration. 

After you enter the required information from the 3rd-party app and click Activate, you are directed to the relevant 3rd-party app’s login screen. Enter your login credentials for this app to verify your account. You'll be directed back to the app’s page in the Clickatell Portal where the integration you’ve just added is shown with an “Active” status.
