I'm trying to send the delivered email webhook from Postmark to Keen. When I paste the webhook URL with the API key in the Postmark admin screen form and click check it works fine. (201 status code.) But then I save it and the check no longer works - it says not authorized.
It turns out the URL is too long - Postmark restricts it to 255 char. So when I save it the end of the key gets cut off.
The 'write' key on Keen is huge. (And I definitely don't want to use the master key!) Any solutions to create a shorter API key on Keen?
