The evidence is produced as a single evidence pack that contains the full transaction audit trail, signer session recordings, identity validation data, and all additional evidence material. This API can be called multiple times, but only after the transaction has been completed. The evidence is returned as a PDF file to be downloaded. ## Syntax ```http GET /api/transaction/uuid: transaction_id/document/AuditTrailDocument/pdf ``` ## Examples ### Example request ```http GET api/transaction/dcaad720-d1e9-47ba-a76b-a6370ef0373b/document/ AuditTrailDocument/pdf/ HTTP/1.1 Host: onespan.com Accept: application/pdf ``` ### Example response ```http HTTP/1.1 200 OK Vary: Accept Content-Type: application/pdf TWFuIGlzIGRpc3Rpbmd1aXNoZWQsIG5vdCBvbmx5IGJ5IGhpcyByZWFzb24sIGJ1dCBieSB0aG lzIHNpbmd1bGFyIHBhc3Npb24gZnJvbSBvdGhlciBhbmltYWxzLCB3aGljaCBpcyBhIGx1c3Qg b2YgdGhlIG1pbmQsIHRoYXQgYnkgYSBwZXJzZXZlcmFuY2Ugb2YgZGVsaWdodCBpbiB0aGUgY2 ... 9udGludWVkIGFuZCBpbmRlZmF0aWdhYmxlIGdlbmVyYXRpb24gb2Yga25vd2xlZGdlLCBleGN1 ZWRzIHRoZSBzaG9ydCB2ZWhlbWVuY2Ugb2YgYW55IGNhcm5hbCBwbGVhc3VyZS4= ``` ### Headers The following headers are included in the request and the response: #### Request headers - [Accept](https://tools.ietf.org/html/rfc7231#section-5.3.2): The response content type depends on the Accept header. - [Authorization](https://tools.ietf.org/html/rfc7235#section-4.2): The OAuth/JWT token to authenticate. #### Response headers - [Content-Type](https://tools.ietf.org/html/rfc7231#section-3.1.1.5): application/json ### Status codes
