Unable to send attachment using Postman using multipart/form-data

[Suggy]

We are trying to send an attachment using multipart/form-data in postman and get this error:

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

The same is working from ServiceNow REST API explorer.

I have seen similar post since 2015 but no correct answers till now 🙂

Note: I have done entirely on my instance.....

So, I have reproduce your steps in my instance. 

I think you should also follow the same, I guess the version of POSTMAN you are using is not current version so just upgrade it or use the current version of Postman here is the steps that I followed.

Inside Body ---> Form-data ---> file (File) type.....

Authentication used : Basic 

Also no need to configure Header in this case rather 

Inside Authorization.... 

Step 1: 

Step 2: Hit that send button...... yessss....

Here is the Sample response....

Also, it seems that you have taken some external post or your org might be using some  and might have came to the conclusion that it can't be done, also try to use above steps....
