No-code automation

n8n

HTTP Request and Webhook nodes, cloud or self-hosted.

n8n's HTTP Request node sends SMS through the API and its Webhook node receives SMS Bridge events. Works the same on n8n cloud and self-hosted.

How it connects: n8n calls the SMS Bridge API itself — no extra tool needed. Your API base is https://api.99billingsolutions.com.

What you can do

• Send SMS from any workflow
• Trigger workflows from inbound SMS
• Route AI drafts for review

Setup

1. Sending: add an HTTP Request node. Method POST, URL your API base + /v1/messages/send, a Header Auth credential named x-api-key, and a JSON body with from_number, to_number and content.
2. Receiving: add a Webhook node (POST), activate the workflow, and add its production URL in SMS Bridge under Settings → Webhooks.
3. Self-hosted n8n must be reachable over public HTTPS for webhooks to arrive.

Field names and error codes are in the send message reference; webhook payloads and signatures in Webhooks. Missing something? Tell us.
