Unable to Select Studio Flow in Phone Number Configuration – Twilio Support

Issue

This article provides guidance on how to manage situations where you need to select an older Twilio Studio Flow through the Twilio Console. The interface currently displays only the 50 most recent Studio Flows, which limits access to older flows that fall outside this range.

Product

Twilio Studio

Environment

legacy Twilio Console

Cause

It is true that older Flows do not appear in the selection list, as the dropdown currently displays only the 50 most recently created Flows.

Resolution

There is a workaround that allows you to enter your Flow of choice instead of selecting from the dropdown.

Workaround using Twilio Console

Copy your Flow's Webhook URL. The Webhook URL can be found by clicking on the Trigger widget on your Flow Canvas.
Load your Twilio number's configuration page.
Under A Call/Message comes in, select Webhook
Paste your Flow's Webhook URL into the URL field
Also paste your Flow's Webhook URL under Call status changes
Click Save Configuration at the bottom of the page
This will update your Phone number's configuration to direct your calls/messages to your Studio Flow.

Workaround using Phone Number REST APIs

Copy your Flow's Webhook URL. The Webhook URL can be found by clicking on the Trigger widget on your Flow Canvas.
Using IncomingPhoneNumber resource, update SMS/Voice url as shown below:

curl -X POST "https://api.twilio.com/2010-04-01/Accounts/$TWILIO_ACCOUNT_SID/IncomingPhoneNumbers/PNaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.json" \
--data-urlencode "SmsUrl=https://webhooks.twilio.com/v1/Accounts/ACXXXXX/Flows/FWXXXXX" \
--data-urlencode "VoiceUrl=https://webhooks.twilio.com/v1/Accounts/ACXXXXX/Flows/FWXXXXX" \
-u $TWILIO_ACCOUNT_SID:$TWILIO_AUTH_TOKEN

This will update your Phone number's configuration to direct your calls/messages to your Studio Flow.
