The request works fine in Postman, cURL, or SoapUI but not in Mule

If you are using Postman, at first you must export as cURL: How to export Postman request as a cURL command to help MuleSoft Support

In Mule, we need to enable the HTTP wire logging to see the request and response: How to Enable HTTP Wire Logging for the HTTP Connector

Request structure

On the first line of the log, we can see:
-Method
-Endpoint
-HTTP protocol
In the following lines the headers with the values.
After headers, the body.

The same structure applies for the response.

If you are using SoapUI:

You will see something like this:


In Mule, you can see the same in the logs.


We are now able to check if the requests are equals by comparing the requests.

If you are sing cURL (or Postman)

Using -v parameter in the cURL command, we enable verbose mode

Using Mule:

Find the HTTP Wire Logging at the mule EE log, the API log or the Studio console


In this case, the header "Postman-Token" was generated on Postman and it is not needed and the header "Name" is different between requests. (The response is good on both cases because is a dummy API REST)
