A mechanism in which a system automatically sends an HTTP request to a specified endpoint upon the occurrence of an event. Typically includes event data and a signature for authenticity verification.
Why it matters
Reverses the direction of integration: the system notifies about an event the moment it happens — payment, new lead, publication. The response is immediate, without polling.
What's missing without it
Without callbacks, integrations continuously poll 'has anything changed?' — causing delays and costing thousands of unnecessary requests.
When it is used
Used in event-driven integrations: payments, forms, automation between systems.
How we use it
After completing audio rendering in VoiceStudio, the worker notifies the CMS via webhook about the ready file.
