Events are pushed to your endpoint the moment they happen — stop repeatedly checking an API for something that hasn't changed yet.
Every payload carries an X-6X-Signature header so your endpoint can verify a request genuinely came from 6X before trusting it.
See every delivery attempt and its response status in your Wholesale Portal — debug a misconfigured endpoint without guessing.
Add up to 5 endpoints yourself, subscribe to whichever events matter to you — no approval wait, no extra cost.
Inbound and outbound SMS (sms.inbound, sms.sent), verification results (flash_verification.completed), and staff/HR events (clock-in, clock-out, leave requests and approvals) — more event types are added as new features ship.
Every request carries an X-6X-Signature header — an HMAC-SHA256 signature of the request body using a secret unique to your webhook — so you can verify a payload genuinely came from 6X before trusting it.
Up to 5 endpoints per wholesale account, each independently subscribed to whichever events you choose.
Delivery is attempted and retried on failure rather than dropped silently — build your endpoint to be idempotent (safe to receive the same event more than once) as good practice for any webhook consumer.
Yes — every delivery attempt for each webhook is logged in your Wholesale Portal, including the response status, so you can debug a misconfigured or unreachable endpoint.
Yes — self-service webhook configuration is included free with any approved wholesale account, no separate subscription or per-event fee.
Register free, subscribe to the events you need, and 6X pushes them to your endpoint from day one.
