Sort of.
1- Please see the thread Trigger API Workflows with GET Requests - #26 by aestela to get updates on the longer-term fix. Bubble’s team still insists this is some kind of “new feature” and who knows when it will get prioritized.
2- In the short term, only fix is to have your webhook go somewhere else (I set up a listener using Google AppScript, someone else set up a node script on a server), then have that API replace periods with underscores and forward to bubble. A hack solution but we’re forced to do this.
