Product: EDI platform

You can now add a mapping to destination webhooks to automatically transform transactions before delivering them to external APIs. Stedi parses EDI files into Guide JSON, which reflects the structure of an EDI transaction in a modern format. You can use a mapping to transform Guide JSON into the shape required by your internal systems and business applications. Mappings provide a visual interface for building JSON-to-JSON transformations and are available in the [Cloud and Enterprise plans](https://www.stedi.com/pricing).

To add a mapping to a destination webhook:

1.  Use the [mappings editor](https://portal.stedi.com/app/mappings) to create a transformation for the `transaction.processed.v2` event.

2.  Select the mapping in the **Mapping** menu when creating a `transaction.processed.v2` event binding.
