Send WhatsApp from your n8n app

aulm is a hosted WhatsApp gateway — flat pricing, webhooks, multi-number support. No Meta approval required. Works with n8n through a tiny backend layer.

Three steps

  1. Create an account and scan the QR code to pair your number.
  2. Paste the prompt below into n8n to scaffold the sender + webhook.
  3. Send your first message via POST /v1/messages/send-text.

Ready-to-paste prompt:

Use an HTTP Request node for sends (method POST, the aulm URLs, Header Auth credential = Authorization: Bearer <AULM_API_KEY> stored in n8n credentials). For inbound, use a Webhook trigger node followed by a Code node that verifies the x-aulm-signature HMAC over the raw body before processing.

See the full Quick Install section in docs for the complete core prompt.
