A booking system, a cash register, a loyalty app, a homemade customer list — if your developer can make it tell Hamla when something happens, Hamla can market on it. This page is written for them; show it to whoever handles your tech.

Connect Custom API
🔒 Your tools send updates to Hamla — we never reach into your systems.
What you get
✓For the developer: one HTTP request
POST JSON to a Hamla webhook endpoint — a contact identifier, an event name, and any fields you want usable in messages. You define the schema.
✓History without side effects
Send a timestamp with each event and you can backfill years of history without triggering campaigns on old activity.
✓For the owner: it feels like any other connection
Once your developer sets it up, you use it like Salla or Calendly — pick the moments, approve the messages, watch it run.
How it works
- Create a webhook endpoint in Hamla — it gives you the URL and the expected shape.
- Your system POSTs events to it as they happen.
- Each event becomes a moment the owner can attach campaigns to — no more code involved.

Custom API integration questions
I'm not technical — is this page for me?
It's for your developer — that's deliberate, and it's the only page on this site written for them. What they set up once, you use without touching code.
What does the payload need?
JSON with a contact identifier, an event name, and whatever fields you want available in messages. Everything else is yours to define.
