Starting a Twilio Studio Flow via Zapier Webhook

Hey everyone, I’m stuck and could use some help. I’ve been trying to kick off a Twilio Studio flow using Zapier, but I’m hitting a wall.

I’ve got the authentication sorted (I think) by putting the Account SID and Auth token in the URL. But now I’m struggling with passing the To, From, and Parameters data.

Right now, I’m getting an error saying “Missing required parameter To in the post body”. I’ve set up my Webhook Zap, but it’s not working as expected.

Has anyone successfully done this before? Any tips on how to properly format the data in Zapier to trigger the Twilio Studio flow? I’d really appreciate any insights or examples you could share.

Thanks in advance for your help!

I’ve gone through this exact headache with Twilio and Zapier before. Here’s what finally worked for me:

Make sure you’re using a POST request in your Zapier webhook. In the ‘Data’ section of the Zapier webhook setup, you need to include a JSON object with all the required fields. It should look something like this:

{
“To”: “+1234567890”,
“From”: “+0987654321”,
“Parameters”: {“key1”: “value1”, “key2”: “value2”}
}

Don’t forget to set the ‘Content-Type’ header to ‘application/json’ in Zapier.

Also, double-check that your ‘From’ number is actually a Twilio number associated with your account. That tripped me up for a while.

If you’re still having issues, try using Zapier’s logging feature to see exactly what’s being sent in the request. It can be a lifesaver for debugging these kinds of integration problems.

hey climbinglion, try sendin the ‘to’ within the request body, not as a url param, and check your valid twilio sender. worked for me once; hope it works for you!

I encountered a similar issue with Twilio Studio and Zapier. The solution was to ensure that all required parameters are sent in the request body as JSON rather than as URL parameters. In Zapier, configure your webhook to use a POST request, include the necessary details such as To, From, and any custom parameters in the data section, and be sure to set the Content-Type header to application/json. Also, verify that the From number is a valid Twilio number tied to your account. Logging the request details in Zapier can assist you in confirming that the data format is correct and help troubleshoot any remaining issues.
