It can be used to receive data from other sources and then continue executing the workflow and use the data received. ## Node Functionality It acts as a way to pause the workflow execution until a webhook payload is received. It can: * Keeps the workflow execution in Running state until payload is received. * Match the security headers of webhook. ## Configuring Node In the node, the `Webhook URL` that is available should be configured in the third party application webhook setup to receive the payload in Refold. Wait for Webhook Node in Refold Optionally, you could also setup `Security Headers` which will be matched with the headers received in the Webhook. If the headers match, Refold will successfully continue executing the workflow, else the node errors and the workflow stops.
