Twilio Trigger and Action reference

Start from Twilio Event Streams and automate SMS, MMS, WhatsApp, voice calls, and custom API requests.

Authentication

Store a Twilio Account SID and Auth Token in a connected FastHook account.

• Trigger account type: api_key; reconnect by replace_credentials.
• Action connection type: api_key; available modes: Connected Twilio account.

Create or reuse the account from a Trigger or Action dialog, or manage it under Settings → Connected accounts. See Authentication and permissions for scopes and access diagnostics, or Connected accounts for reuse, reconnect, revocation, and credential rotation.

Scopes and permissions

The Trigger manifest does not declare a fixed base OAuth scope list. Installation access, API credentials, or the selected event configuration can still control available resources.

Operation-specific requirements appear in the tables below. Custom event selections can add scopes dynamically, so the current Trigger or Action dialog remains authoritative for the exact consent request.

Use Twilio as a Trigger

The current provider manifest contains 177 available Trigger definitions. Representative definitions include:

• Any Twilio Event
• Custom Twilio Events
• Messaging Inbound Message Received
• Messaging Message Delivered
• Voice Status Callback Call Completed
• Studio Flow Execution Ended

Choose the narrowest event definition that fits the Workflow. Configure provider-specific resource and event filters in the Source dialog before adding broader Workflow Filters.

Use Twilio Actions

The current Action manifest contains 5 operations. Representative Actions include:

• Send SMS
• Send MMS
• Send WhatsApp Message
• Make Call
• Custom API Request

The Action editor reads its required permissions, fields, remote resource pickers, output schema, and rate limit from the provider manifest. Available fields can change with the selected operation and authentication mode.

Build a Workflow

1. Create a Source using a Twilio Trigger definition.
2. Create a Workflow with that Source as its Trigger.
3. Add the required Twilio Action and select the connected account.
4. Map Trigger or earlier-Step data into the Action fields with the field picker.
5. Add a Filter, Paths, Delay, or Transformation when the route needs it.
6. Activate the Workflow, produce a controlled event, and verify the run in Audit and in Twilio.

Troubleshooting Twilio

The account is missing or cannot be selected

Confirm the active FastHook team, provider, account status, and authentication mode. A disabled or revoked account cannot execute an Action.

A resource picker is empty

Verify that the connected provider identity can access the resource itself. OAuth consent does not add workspace, repository, channel, drive, project, base, or record permissions.

The editor asks for additional scopes

Reconnect the same account from the affected Trigger or Action so FastHook can request its current manifest scopes. Then reopen the editor and select the resource again.

An active Workflow returns 401, 403, or a permission error

Compare the selected operation’s access requirements below with the account recorded in Audit. Check provider-side membership and object access before repeating the Action.

The provider returns 429 or a temporary 5xx

Inspect the Step attempt and retryability in Audit. FastHook can retry temporary failures, but provider quotas and idempotency rules still apply.

Provider-specific checks

• The Twilio event catalog is broad; select explicit event types when possible.
• Rotate the Auth Token in both Twilio and FastHook if it may have been exposed.
