I am trying to create transient document in adobe sign using rest api. After lot of research I was able to make the correct multi form request in Salesforce Apex.But now I am getting the file content missing error when I checked the debug log in adobe sign Account. Below is my code snippet:

 String boundary = '----------------------------741e90d31eff';
      String header = '--'+boundary+'\nContent-Disposition: form-data; name="file"; filename="testsign.pdf";\nContent-Type: application/octet-stream';

  String footer = '--'+boundary+'--';             
  String headerEncoded = EncodingUtil.base64Encode(Blob.valueOf(header+'\r\n\r\n'));
 while(headerEncoded.endsWith('='))
  {
     header+=' ';
     headerEncoded = EncodingUtil.base64Encode(Blob.valueOf(header+'\r\n\r\n'));
  }
    Blob testFileContent = Blob.valueOf('test file is sdfsdfsfs');
 // Blob testFileContent =[SELECT VersionData FROM ContentVersion WHERE ContentDocumentId = '0690x000001OhAu'][0].VersionData;
  String bodyEncoded = EncodingUtil.base64Encode(testFileContent);
    system.debug('bodyEncoded'+bodyEncoded);

  Blob bodyBlob = null;
  String last4Bytes = bodyEncoded.substring(bodyEncoded.length()-4,bodyEncoded.length());

 if(last4Bytes.endsWith('==')) {
    system.debug('inside first');
    last4Bytes = last4Bytes.substring(0,2) + '0K';
    bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;

    String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
    bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);
  } else if(last4Bytes.endsWith('=')) {
    system.debug('inside second');
    last4Bytes = last4Bytes.substring(0,3) + 'N';
    bodyEncoded = bodyEncoded.substring(0,bodyEncoded.length()-4) + last4Bytes;

    footer = '\n' + footer;
    String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
    bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);              
  } else {
    system.debug('inside third');
    footer = '\r\n' + footer;
    String footerEncoded = EncodingUtil.base64Encode(Blob.valueOf(footer));
    bodyBlob = EncodingUtil.base64Decode(headerEncoded+bodyEncoded+footerEncoded);  
  }
  system.debug('bodyBlob'+bodyBlob);
  HttpRequest req = new HttpRequest();
  String authorizationHeader = 'Bearer ' +acceessToken;
  req.setHeader('Authorization', authorizationHeader);
  req.setHeader('Content-Type','multipart/form-data; boundary='+boundary);
  req.setMethod('POST');
  req.setEndpoint('https://api.in1.echosign.com/api/rest/v6/transientDocuments');
  req.setBodyAsBlob(bodyBlob);
  req.setTimeout(120000);

  Http http = new Http();


    try{
        HTTPResponse res = http.send(req);

And following is response from adobe sign:

Metadata
x-request-id : ecca058a-02b7-4dfe-8e9a-a64869798407
content-type : application/json
status : 400

Body
{
     "code": "NO_FILE_CONTENT",
     "message": "Must provide file body"
}

Please anyone if have face same issue do help me wiht it what i am missing out here.

One thing to try, looking at https://secure.na1.echosign.com/public/docs/restapi/v6#!/transientDocuments/createTransientDocument

The parameter name is "File" not "file", HTTP parameters can be case sensitive. Try changing name="file" to name="File" in line 2.

I tried with vNHttpFormBuilder class also but it was giving as "bad request:file content missing error"

After some efforts,I concluded the request have to be key-value pair format. So I have tired below solution, it is working fine now, but the only issue is that I have to convert the content of vf page into string and send the data.

 PageReference ref = page.Account_Details;
        ref.getParameters().put('Id','0010x00000hw6XzAAI');
        // test
        HttpRequest req = new HttpRequest();

    // Set method and endpoint  
    req.setEndpoint('https://api.in1.echosign.com/api/rest/v6/transientDocuments');
    req.setMethod('POST');

    // Set body
    String boundary = '----------------------------' + String.valueOf(DateTime.now().getTime());
    String body = '--' + boundary + '\r\n';
    body += 'Content-Disposition: form-data; name="File-Name"\r\n\n';
    body += 'test.pdf\r\n';
    body += '--' + boundary + '\r\n';
    body += 'Content-Disposition: form-data; name="Mime-Type"\r\n\n';
    body += 'text/html\r\n';
    body += '--' + boundary + '\r\n';
    body += 'Content-Disposition: form-data; name="File"\r\n\n';
    body += ref.getContent().toString()+'\r\n';
    body += '--' + boundary + '--';
  //  Blob bodyBlob = EncodingUtil.base64Decode(body);
  //  req.setBodyAsBlob(bodyBlob);
    req.setBody(body);
    // Set headers
    req.setHeader('Content-Type', 'multipart/form-data; boundary='+boundary);
    //req.setHeader('Content-Length', String.valueof(body.length()));
    req.setHeader('Authorization','Bearer ' +IntegrationKey);
    system.debug('req: ' + req);
    system.debug('req.header.contenttype: ' + req.getHeader('Content-Type'));
    system.debug('req.header.contentlength: ' + req.getHeader('Content-Length'));
    system.debug('req.body: ' + req.getBody());

    // Send HTTP request and get HTTP response
    Http http = new Http();


    try{
        HttpResponse res = http.send(req);
        system.debug('res: ' + res.getBody());
        System.debug('transient document = : '+res.getStatusCode() + 'status'+res.getStatus());  
        if(res.getStatus() == 'OK' && res.getStatusCode() == 200){
            AdobeSignWrapperClass adobeWrap = AdobeSignWrapperClass.parseJson(res.getBody());
            system.debug('testd'+adobeWrap);
            system.debug('sdada'+adobeWrap.transientDocumentId);
            if(String.isNotBlank(adobeWrap.transientDocumentId)){
                transientDocumentId = adobeWrap.transientDocumentId;
                system.debug('success');
                sendAgreements();
            }

        }
    }
    catch(Exception e){   
        system.debug('error is'+e);
    }
    return agreementId;

However, what we want over here is we want to send the pdf version of VF page or a contentversion of pdf. So in place of

body += ref.getContent().toString()+'\r\n';

if we use

body += ref.getContentasPDF();

and instead of

body += 'text/html\r\n';

we use :

body += 'application/pdf\r\n';

the document is not being sent over there properly and it is showing bad content error.

  • To me it seems that you would still need to base64Encode(ref.getContentasPDF()), and then have some type of solution in place that safely pads the data like you previously had. – Craig Johnson Nov 2 '19 at 19:40
