Steps
In the Admin Panel, go to Settings > Integrations > Webhooks and create a webhook for a specific action, such as a Customer (member) Update
Optionally configure a shared secret for the webhook when creating it
On receipt, compute an HMAC-256 digest using the shared secret and the request data, and compare it to the X-Nexudus-Hook-Signature header
Return a successful response promptly; Nexudus retries failed deliveries at delayed intervals up to 10 times
Parse the event-specific payload (for example, updated contact/member data) to sync into your own system
Known gotchas
Signature verification is only possible if a shared secret was configured for that webhook — webhooks created without one can't be cryptographically verified
After 10 failed retry attempts Nexudus stops retrying, so monitor delivery failures to avoid silently missing events
