Smooch makes it possible to manage your WeChat access tokens through a third party. This allows Smooch and another service to make API calls to WeChat simultaneously without conflicts.
In order to configure third party access token endpoints, you must integrate WeChat to Smooch via the REST API. It is not currently possible to configure the required parameter through the UI.
The WeChat integration endpoint now accepts an optional property accessTokenUrl. Once this property is set, Smooch will call the new endpoint to generate access tokens.
See below for an example of an API call to configure WeChat with third party access token service:
