WireMock

If the callback URL is a normal query parameter then JSONPath extraction won’t work.

Try something like:
```url": "{{originalRequest.query.callback_url.0'}}"```

thanks. I think my question is not clear enough.
My problem is that the body recevied on the callback_url is empty.

Not sure I understand what you mean - can you elaborate?

i receive POST on the callback_url.
but the received body on the callback_url is empty.

What do you mean “body on the callback_url”?

The HTTP request body sent to your target endpoint?

Ah, I see the problem - `jsonBody` isn’t supported for webhooks

Use `body` instead, which needs to be a String

ok.. thanks.
does it mean that i cannot use jsonbody in webhooks?

I have another quey. but it is a bit of explanation required for it.

here it is:

i want to return a random request id in response and use the same request id in callback body. Is it possible ?

i am putting this on the main chat window .. thanks
