fast webhook delivery that won't lose your events

"come hither, herald. Let the trumpet sound, And read out this."

$ what it is

Lean, reliable webhook delivery API. You POST each event, along with the destination, through us. We make sure it reaches that destination. Retries, security, a dead-letter queue so you never lose events.

Companies typically underestimate how long it takes to build a fully featured webhook delivery system in-house. They also underestimate all the overhead that come with managing that system: bad endpoints, security concerns, dropping events.

$ 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 '{"name":"you","email":"you@example.com","invite_code":"BETA-XXXX"}'
# -> { "api_key": "sliq_...", "hmac_secret": "..." }   (shown exactly once)

# 2. queue a webhook
curl -X POST https://api.heraldq.com/v1/webhook \
  -H 'authorization: Bearer sliq_...' \
  -H 'content-type: application/json' \
  -d '{"destination":"https://your-customer.com/hook","payload":{"hello":"world"}}'
# -> 202 Accepted  { "id": "01J..." }

# 3. check it landed
curl -H 'authorization: Bearer sliq_...' \
  https://api.heraldq.com/v1/webhook/01J...
# -> { "status": "delivered", ... }

$ what you get

• Retries with exponential backoff until it lands
• Dead-letter queue with replay for every event that couldn't be delivered
• HMAC-signed payloads verify in a few lines
• Supports idempotency
• Live per-webhook status, delivery history, and an account summary
• Request IDs on every response, so support means "quote the ID", not "describe the vibe"
