In the postman, it looks like this:
A couple of minutes to wait and then we get the response which comes to the link from webhook.site. The response contains a list of the last 25 posts, for the keyword "toyota".
As you can see, it took about 6 minutes to complete the request.
Similarly, callback_url can be used in all POST requests. The webhook link was used just as an example. The main priority is to make the setting on your side so that your application can receive JSON responses from our API.
