Add SMS to any workflow

n8n's HTTP Request node can call any REST API, so you can send SMS through SimGate without installing a custom node. It works the same on n8n Cloud and self-hosted.

Trigger sends from anything n8n supports: a new row in a database, a form submission, a schedule, or an incoming webhook.

Connect n8n to SimGate

Add an HTTP Request node

In your workflow, add the HTTP Request node after your trigger.

Configure the request

Method POST, URL https://api.simgate.app/v1/sms/send, and add headers x-api-key (your key) and Content-Type: application/json.

Set the JSON body

Send deviceId, phoneNumber, and message — map message and phoneNumber from earlier nodes using expressions.

Test

Execute the node; the response includes a messageId you can use downstream.
