Im reporting an SMS issue

Hi, I’m using a Vapi-managed Twilio number (+1 516 475 4760). SMS is enabled and my assistant Morgan is assigned, but inbound texts from my phone aren’t triggering any chats even though the text test on my dashboard works fine. Can you please refresh the Twilio Messaging webhook for this number?

Hi Mr V,

It seems there's an issue with your inbound SMS not starting chats, despite setup appearing correct on the dashboard. Please ensure that your Twilio number is correctly configured with SMS capabilities enabled in both Twilio and Vapi. Here's a quick check you can perform:

Import your Twilio number into Vapi: Ensure that your number is imported correctly so Vapi can manage the webhooks. See the import guide here.
Enable SMS for your number: In the Vapi dashboard, verify that SMS is enabled for your number. This should configure the Twilio Messaging webhook to initiate sessions with your assigned assistant for inbound texts. Here's how to set up inbound SMS.

If these steps are confirmed and the problem persists, it may be necessary to refresh the webhook setup manually. Please let me know if further assistance is needed.

@Mr V did you get this figured out? I'm having the same issue and have had not assistance from @Vapi @Vapi Support Bot

To refresh the Twilio Messaging webhook for your number, you can update the number in Vapi by setting smsEnabled: truesmsEnabled: true. Here’s a sample cURL command:

curl -X PATCH https://api.vapi.ai/phone-number/{your_number_id} \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{"smsEnabled": true}'

curl -X PATCH https://api.vapi.ai/phone-number/{your_number_id} \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{"smsEnabled": true}'

This will reconfigure the webhook and should resolve most inbound SMS issues (documentation).
