Outbound REST - Multipart/form-data

[Rshear]

Hi,

Currently working on an outbound REST to 3rd party tool (through a mid server). 3rd party requires mutipart to be sent when sending a file to attach/upload.

Test the POST call on postman and all ok. When in servericenow I'm getting no-where quick 🙂

That said I can get some kind of response just not the one I want (i.e. file uploaded). See REST content:

-----WebKitFormBoundaryAAA

Content-Disposition: form-data; name="file"; filename=${filename};

Content-Type:${contenttype}

${file}

-----WebKitFormBoundaryAAA

${contenttype} comes from the content type of the attachment on the sys_attachment table and ${file} is created using the below (which is in a script include):

-----------------------------------------------------------------------------------

var grAtt = new GlideRecord('sys_attachment');
grAtt.addQuery('table_sys_id', sys_id of attachment);
grAtt.query();

if(grAtt.next()){
var gsa = GlideSysAttachmentInputStream(grAtt.sys_id.toString());
var bytesContent = new Packages.java.io.ByteArrayOutputStream();

gsa.writeTo(bytesContent);
bytesContent.close();

//Get the file content
var mycontentStr = new Packages.java.lang.String(bytesContent.toByteArray());

i then set mycontentStr as a parameter to pass to the rest call.

Any help would be appreciated!...ive scoured the community and read a few things that multipart not supported and to use MId server script include however there seems to be conflicting views on this.

@Ankur Bawiskar Hi Ankur,

I am having an issue with attaching excel and jpegs to third party. The file reaches but we cannot open it. I checked the binary files are going correctly too. We are also using MID server for this integration.

Multipart looks like this in notepad:

Hi,

I would encourage avoid asking secondary question to same post and also since this is older post.

It's better to create a second post so there's a separation in the questions being asked.

please post a question and share the link

I was facing the same issue, got HI team on this and servicenow DOES accepts form-data format, although it wont accept files to be attached (unless you are on LONDON and the Integration Hub plugin needs to be purchased ($$$$), and it will be available ONLY on "Flow Designer" where you could use the "file" form-data as postman does, but instead of using "upload file" it will use the sevicenow sys_id's under sys_attachment_list.do).

Try this:

var r = new sn_ws.RESTMessageV2('<12312312312321>', 'POST');
var var1 = "test1";

var var2 = "test2";

var var3 = "test3";
r.setStringParameterNoEscape('form1', var1);
r.setStringParameterNoEscape('form2', var2);
r.setStringParameterNoEscape('form3', var3);
var response = r.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();

Please mark as this as helpful if it was.

Hi, 

Multipart/form-data requests are now supported via the REST action step in the IntegrationHub which comes as part of the ServiceNow IntegrationHub Installer plugin available for a fee in the Madrid release.

The procedure to set this up is explained in the below knowledge article.
