I have setup texts to be sent out using HTTP posts directly connected to our Twilio account. If someone replies STOP or UNSUBSCRIBE in Twilio, how can I get Twilio to communicate with Infusionsoft and apply an opt-out tag to that contact record? I looked into Zapier, but it didn’t seem like I could get the Zap to look for keywords in the text reply.
You can set up a Zap — the Zap would have a filter at the beginning “if response - “stop”, etc.) it will trigger the zap.
Twilio also has an automation builder in it where you can trigger a web hook to be send to Zapier if they reply back with opt-out words.

Thank you! Within Zapier, I’m setting up the Twilio Trigger event and am not seeing where I can add a filter. I’ve selected the “New SMS” trigger event, but am not seeing a filter for that New SMS. Can you help?
Ah, thanks so much! Very helpful! Getting it setup now. ![]()
