Any examples of a multipart/form-data posting attachment content using REST API

[owainr]

Been struggling with this for ages, able to send the meta data using the POST <instance>/api/now/attachment/file but when using the POST <instance>/api/now/attachment/upload with the content of the file it always returns -

'{"error":{"message":"Failed to create the attachment. File part might be missing in the request.","detail":null},"status":"failure"}'

Tried an array of methods with the multipart in php and none of them seem to return anything other then this

Please help

TIA

I am getting the same error.

I was able to post it using postman. check screenshots below:

Note: Don't supply content type in headers when using postman.

Note from stackoverflow post:

Beware, when testing your webservice using chrome postman, you need to check the form data option(radio button) and File menu from the dropdown box to send attachment. Explicit provision of content-type as multipart/form-data throws an error. Because boundary is missing as it overrides the curl request of post man to server with content-type by appending the boundary which works fine.

Hi Owainr,

Its been confirmed by ServiceNow that they do not support content-type as "multipart/form-data"  .The only solution is either use Mid server or create own proxy server where you can send as Binary Stream .

There are others content-type as "Application/Json" which  you can use.

Just to keep in mid that ServiceNow sends Text data out of ServiceNow.
