n8n

How it works

SendApp doesn't have a dedicated node on n8n: you use the HTTP Request node, included in n8n, to call our API. You can send WhatsApp/SMS messages, create or update contacts and more, orchestrating SendApp together with all the other apps in your workflow.

Send a message from the API (outbound)

1. In your n8n workflow add an HTTP Request node.
2. Set the method to POST and the URL to the SendApp endpoint, for example /api/whatsapp-meta/send or /api/sms/send.
3. In the body (JSON) include your apikey, the account token and the message fields.
4. Run the workflow: the message is sent through SendApp.

You'll find all the endpoints, parameters and examples in the API documentation.

Receive contacts in SendApp (inbound)

1. In your n8n workflow, where you want to send the data to SendApp, add an HTTP Request node in POST to your SendApp Webhook URL.
2. Pass the contact data (name, phone, email) in the body.
3. SendApp creates or updates the contact and tags it: you'll be able to reach it with a campaign or via API.
