What you get

Three primitives. Everything else is composition.

No vendor SDKs, no callback pyramids, no opaque IDs. The API is small enough to read in one sitting.

Send messages

One endpoint for every kind of outbound message. The type is inferred from the fields you set — no opaque schemas, no SDK to learn.

Receive webhooks

Inbound messages, edits, reactions, and delivery statuses POST to your URL as normalized JSON. We dedupe, classify, and persist on our side first — your retries are safe.

Manage privacy & groups

Per-contact read filters applied on ingestion — blocked threads simply return empty. Plus group creation, paginated invites, and contact search.
