Webhook delivery you can rely on.

$ what it is

A lean webhook delivery API. You POST events, we handle retries with exponential backoff, park permanent failures in a dead-letter queue, and sign every outbound payload with HMAC-SHA256 so your receivers know it's really you.

Could you vibe-code your own webhook delivery system in 3 - 6 months? Sure. But do you want to have to "vibe"-debug it for the next 4 years? Didn't think so.

$ the whole API, end to end

# 1. sign up with a beta code, grab your keys
curl -X POST https://api.heraldq.com/v1/signup \
  -H 'content-type: application/json' \
  -d '{"email":"you@example.com","invite_code":"BETA-XXXX"}'
# -> { "api_key": "sk_...", "hmac_secret": "..." }

# 2. queue a webhook
curl -X POST https://api.heraldq.com/v1/webhook \
  -H 'authorization: Bearer sk_...' \
  -H 'content-type: application/json' \
  -d '{"destination":"https://your-app.com/hook","payload":{"hello":"world"}}'
# -> 202 Accepted

# 3. check it landed
curl -H 'authorization: Bearer sk_...' \
  https://api.heraldq.com/v1/summary
# -> { "dispatched_today": 1, "failed_today": 0, ... }
