Signed, retried, and logged

POST a signed JSON payload to your endpoint whenever a subscription is created, changes status, renews, or fails a payment. Each event can be toggled individually. Deliveries are HMAC-signed (X-Milo-Signature), sent asynchronously, retried with backoff for a day, and logged.

What you get

  • Events: created, status changed, renewed, payment failed
  • HMAC SHA-256 signed deliveries
  • Async sending with retry backoff (5m / 30m / 2h / 6h)
  • Delivery log and a payload filter for developers
