WORKFLOW ACTIONS
What you can configure.
Choose an action in the workflow builder, connect an account, and map its inputs. These actions are available in the catalog; your account access and a successful test determine whether they work for your setup.
Call and speak text
Write
Place a call and have Twilio speak a short message with its default voice.
Permissions and limits
Account permissions
Twilio Voice: create calls
A voice-enabled Twilio sender
Operation limits
A queued call receipt confirms acceptance, not that the recipient answered or heard the message. The default Twilio voice is used. A lost create response remains uncertain and is never retried automatically.
A repeated request may repeat the external action. Review the previous result before retrying a write.
Get message
Read
A message's status (queued, sent, delivered, failed, ...) and error code.
Permissions and limits
Account permissions
Depends on the connected account and selected operation. Check the service documentation.
List messages
Read
A page of messages, filtered by the number they went to or came from.
Permissions and limits
Account permissions
Depends on the connected account and selected operation. Check the service documentation.
Pagination: page. Check the result for additional pages; a single action may not return every record.
Send SMS
Write
Send a text message. From is the connection's number unless given.
Permissions and limits
Account permissions
Depends on the connected account and selected operation. Check the service documentation.
Operation limits
Messages beyond the account's send rate are queued, not refused: check status later.
A repeated request may repeat the external action. Review the previous result before retrying a write.
Send SMS, MMS or WhatsApp message
Write
Send text or up to ten HTTPS media URLs. Prefix both phone addresses with whatsapp: for WhatsApp.
Permissions and limits
Account permissions
Twilio Messaging: create messages
An approved sender for the selected channel
Operation limits
A queued receipt confirms acceptance, not delivery. WhatsApp requires an approved sender and an allowed conversation or template. Twilio may ignore text paired with some WhatsApp media types.
A repeated request may repeat the external action. Review the previous result before retrying a write.
SETUP
Start with a controlled test.
01Connect the intended account
Use the account and permissions required for your process. Review the connection check before configuring a workflow action.
02Review inputs and access
Select a listed operation and map its required inputs. Use test records and add a human approval before writes that need review.
03Confirm the result
Inspect step outputs and confirm the result in Twilio. A saved workflow is not a completed provider action.
