NOTE

Some API collections also support a separate API for Raw-X12 EDI transactions. You can send your API request and receive your responses in X12 format instead of JSON by using the Postman tool/platform for testing and investigation the API usage. It is not a substitute for a console used in a business context for processing Eligibility requests and Claims requests of various types.
