Webhooks

Outbound webhook subscriptions for lifecycle events

Register a webhook subscription; the signing secret is returned ONCE

Registers an endpoint to receive push deliveries for the given lifecycle events. Valid event types are offer.accepted, offer.rejected, optin.completed, invitation.accepted, creative.ready, and creative.failed. The response carries a high-entropy signing secret returned only here (store it now); it keys the HMAC-SHA256 X-AdBridge-Signature on every delivery so you can verify authenticity. New subscriptions start active. Requires administrator access to the network.
