Overview

Depending on your use case, certain event related information may be more actionable or valuable to you. When configuring your webhook destination, you can choose the type of payload you want to receive when your expression matches an event in the streaming blockchain data. The available payload types are as follows:

Summary

By offering a variety of payload types, QuickAlerts provides you with the flexibility to receive the information most relevant to your needs. You can select your preferred payload type during the webhook configuration process, and you can update this selection at any time. Please note: Editing the payload type for a webhook destination will affect all QuickAlerts which use that destination.
