# CMS-1500 PDF: Business Identifier

> Retrieve a Stedi generatedCMS-1500 Claim Form PDF for a submitted 837P (professional) claim by business identifier

This endpoint uses a business identifier to retrieve autogenerated CMS-1500 Claim Form PDFs for submitted 837P professional claims.

1. Call this endpoint with the `businessId` query parameter set to the claim's correlation ID. The correlation ID is returned as the `claimReference.correlationId` in the synchronous response Stedi returns when you submit a professional claim.
2. The endpoint returns an array of PDFs for all claims with the specified `businessId` value. PDFs are returned as a base64 encoded string.

To view a PDF, decode the base64 string and save it to a file with a `.pdf` extension.

<Note>
  If you plan to send these PDFs to payers or retain them for your records, we strongly recommend visiting [CMS-1500 Claim Form PDF](/healthcare/cms-1500-claim-form-pdf) for information about how to structure claim submissions for optimal generation, the correct printer settings for generated PDFs, and general best practices.
