InboxLee POSTs a JSON payload to a URL you configure whenever one of the subscribable events happens. Use this to wire any tool - Slack, PagerDuty, your billing system, an internal CRM.
Available events
Configuring
In InboxLee → Settings → Webhooks → Create. Provide a URL, select events, choose a signing secret. InboxLee signs every payload with HMAC-SHA256.
Verifying signatures
X-Inboxlee-Event: blacklist.hit X-Inboxlee-Signature: sha256=<hmac-hex>
Recompute HMAC-SHA256 of the raw request body, keyed by your signing secret, and compare it to the hex in the header. Reject the payload if it does not match. Compare over the raw body, not a re-serialised object - key order matters.
Retry policy
On a non-2xx response or a network error, InboxLee retries with exponential backoff - 1, 2, 4, 8, 16 minutes, then capped at 30 - for up to 6 attempts before the delivery is marked failed. The dashboard surfaces failed deliveries so you can investigate.
