ReadyAPI is not reading a json file

I have a post request in which i attach two files, the first one must be a json file.

Using postman, the api works fine but using soap ui it seems like it's not reading the right format.

How is it possible ?

Re: Soap ui (free version) is not reading a json file

Hey @abirHajali,

I have this a lot where the request works fine in postman, but doesnt in readyapi! or soapui. You gotta remember postman doesnt include all the functionality that soapui and readyapi! include to allow the user to tailor their requests....thats why i think this occurs so much.

What i do in this situation is i use Fiddler to proxy the requests. Fiddler is a tool that extracts all the RAW content from any tool that uses it as a proxy and allows you to compare the difference between what soapui sends and what postman sends. This then allows you to make the appropriate changes in soapui to get it to work.


if this helped answer the post, could you please mark it as 'solved'? Also if you consider whether the title of your post is relevant? Perhaps if the post is solved, it might make sense to update the Subject header field of the post to something more descriptive? This will help people when searching for problems. Ta

Re: Soap ui (free version) is not reading a json file

Hi @abirHajali,


Did you fill the "Attachments" part of your POST request ?


Be aware that SoapUI will automatically fill in the "Content type" field, and it should be changed for a json file.
You can also have a look at the documentation page:
