The What, Why, and How of Payload Transformations

Transformations allow customers to modify select aspects of a webhook, such as the payload and URL, before it's dispatched by writing short JavaScript functions that can be written in the app portal or updated with the Svix API. This feature enables customers to send events directly to an external service's API in whatever format the service requires, vastly speeding up their workflow and allowing them to interface with different applications without having to set up a functional web server to receive and forward webhooks. The transformations can be used for various purposes such as modifying event types, manipulating payload data, or scrubbing PII from sensitive information. With this feature, customers have more control over the format of their webhooks, making it easier for them to integrate with different applications and services.
