When a call or lead changes, another tool may need to know. A webhook is an event message sent to a connected system, helping you carry the relevant information into the next part of your workflow. 01 #### Connect events to a real next step Choose which call or lead events matter to the receiving system. Start with a focused use, such as keeping an internal lead process informed. 02 #### Test the receiving system Check that the destination accepts the event and handles the information correctly. A delivery is only useful when the receiving tool knows what to do with it. 03 #### Make failures reviewable Inspect delivery results and resend failed attempts where appropriate. The receiving system should handle retries without creating duplicate work.

What is a webhook in plain language? + It is a message one system sends another when something happens. Instead of repeatedly asking whether a call changed, your connected tool can receive an event about it. Can I retry a failed delivery? + The event-delivery workflow provides testing and resend controls. Check the reason for a failure first and make sure the receiver can handle repeated deliveries safely. Connect the next step ### Works with the rest of your call workflow.
