Step 0: If you are just using this app to subscribe to webhook events: STOP you are done! Just update the delivery URL on the main marketplace app settings page. You do not need a token exchange.
Step 1: Click the button below to copy the "code"
Step 3: Paste in the code in the box. Go and get your client id and secret and paste those in too. Scroll to see next step.
Step 4: Scroll down and click "omit refresh token" and then click "Send API Request"
Step 5: CONGRATS! You will now get your access token and refresh token! Webhook events will now start sending to the webhook URL if you put one in. NOTE: The access token is only good for 24 hours. If your API calls quit working, then paste the token in this same box, switch grant_type to "refresh_token" and click "omit code" to attempt to get it manually refreshed. If you want to get fancy, you can save your refresh token in a variable in Make's data store and run the get access token call to help refresh it.
