Send Notifications to WhatsApp

WhatsApp Cloud Send Message sends a text message through Meta’s WhatsApp Cloud API. The action requires a saved connection containing the access token, a Meta phone number ID, a recipient phone number, and message text. It does not implement a template-message editor in this action.

Prepare the WhatsApp connection

Obtain a suitable WhatsApp Cloud API access token and phone number ID from your Meta developer setup.

Open Agent Workflows → Connections → Add New.

Set Integration to whatsapp, enter a label, and choose API Key for the access token.

Enter the token in the API Key field and save the connection. The built-in verifier recognizes the whatsapp identifier and checks the token during creation.

Configure WhatsApp Cloud Send Message

Add the WhatsApp Cloud Send Message action to your workflow.

Choose the saved connection in WhatsApp access token connection.

Enter Phone number ID (from Meta).

Enter the recipient in Recipient phone (digits, country code, no +). The action removes non-digit characters before sending.

Enter the message in Message (supports {{trigger.fields.*}} tokens). Trigger field tokens can be interpolated before the action runs.

Save the workflow and test with a recipient and message you are authorized to contact.

Understand the result

The action sends a JSON text-message request to Meta’s Graph API and returns a success or error result, including the HTTP status when available. A successful API response does not guarantee that a person read the message. Review the node result and the provider’s message status separately when diagnosing delivery issues.

Use a controlled test and avoid including credentials or unnecessary personal data in message text. For credential masking and connection management, see Manage Workflow Connections.
