I am using the podio-php api to create an application, however the application that I dynamically create requires a webhook. Since the webhook requires the app_id and app_token of the app, how would I be able to programmatically retrieve the app_token? (I have already contacted support to apply for access, they redirected me to the podio stackoverflow tag)
You can get the token from Get app API method in Podio. But you need special privilege for your API Client/Secret to do that. For normal API Client the token field will be empty. You can get the special privilege to your Client Id by writing to Podio.
