Decline Reason

Hi nehme, You can refer to this guide to retrieve decline reason. It's stored at the "content" within "messages" attribute at package level:

DocumentPackage documentPackage = client.GetPackage(packageId);
IList messages = client.GetPackage(packageId).Messages;
Debug.WriteLine(documentPackage.Status.ToString() + " reason : " + messages[0].Content);

And this is the construction of the messages JSON:

"messages": [
    {
      "status": "NEW",
      "from": {
        "group": null,
        "language": "en",
        "signature": null,
        "id": "a8e907ec-9472-4cb9-812a-efe5af88ed1b",
        "data": null,
        "title": "",
        "auth": {
          "scheme": "NONE",
          "challenges": []
        },
        "updated": "2018-05-02T15:56:02Z",
        "external": null,
        "knowledgeBasedAuthentication": null,
        "email": "[email protected]",
        "firstName": "john",
        "lastName": "smith",
        "phone": "",
        "professionalIdentityFields": [],
        "userCustomFields": [],
        "company": "",
        "delivery": {
          "download": false,
          "email": false,
          "provider": false
        },
        "address": null,
        "created": "2018-05-02T15:56:03Z",
        "name": "",
        "specialTypes": []
      },
      "content": "I do not wish to sign electronically.",
      "created": "2018-05-04T19:13:22Z",
      "to": [],
      "documents": []
    }
  ]

And you may want to make sure your package status is in DocumentPackageStatus.DECLINED Hope this could help! Duo
