Results where
your systems already are.

Submit evidence through short-lived upload sessions, get notified by signed webhooks, and read results through a typed SDK. For loyalty programs, approved submissions post straight into Open Loyalty as transactions or custom events, with every delivery recorded in a ledger you can retry.

What it does for you.

Sessions and idempotency

Open a session, upload to pre-signed URLs, submit. Client submission ids make retries safe. Batch references group campaigns.

Signed webhooks

Session and submission events signed with HMAC SHA-256 and deduplicated by id. A test endpoint is one call away.

Typed SDK

A TypeScript client covering the API and webhook signature verification.

Open Loyalty delivery ledger

Delivered, failed, skipped, or pending, per submission and target. Automatic retries, manual retry, exactly-once per submission.

How it works in practice.

  1. Create a session

    Receive upload URLs for the evidence.

  2. Submit

    Steve processes, verifies, and routes.

  3. Receive

    Webhook fires. Read the result, or let Open Loyalty award the points.
