> This new endpoint allows you to use a Stedi business identifier (the claim’s correlation ID) to retrieve the CMS 1500 PDF for submitted 837P claims.

Published Mar 6, 2025

Product: Claims

This new endpoint allows you to use a Stedi `business identifier` (the claim’s correlation ID) to retrieve the CMS-1500 PDF for submitted 837 professional claims.

1.  Call the endpoint with the business identifier as a query parameter for the claim form PDFs you want to retrieve. The business identifier should be the claim’s correlation ID. You can find this value in the `claimReference.correlationId` property in the synchronous responses from the [Professional Claims](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-claims) and [Professional Claims Raw X12](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-claims-raw-x12) endpoints.

2.  Stedi returns an array of PDFs for all claims with the specified business identifier value. The PDFs are returned as a base64 encoded string.

3.  Decode the base64 string and save it to a file with a .pdf extension.

Visit the [CMS-1500 PDF: Business Identifier API docs](https://www.stedi.com/docs/healthcare/api-reference/get-pdf-1500-business-identifier) for complete details.
