If I'm not mistaken (I could certainly be), couldn't the code Chayce so graciously provided be embedded in a formula url button - such that at the press of a button, the code retrieves the userID and places it in a field value. That field value in turn could be referenced in a webhook, which executes the API_AddUserToRoll call. Is that right?
If so, I just can't figure out the code to append to Chayce's - the code that would take the retrieved userID and enter it into a field value.
I'm really sorry for the training wheels with this - I'm somewhat new to this kind of QB development, but I'm quite eager to learn.
Thoughts?
