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
- Create an account and scan the QR code to pair your number.
- Paste the prompt below into n8n to scaffold the sender + webhook.
- 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.
