Send POST requests as usual with your chosen language. ZenRows will transparently forward the data to the target site.

Before trying on your target site, we recommend using a testing site like to see if the parameters are sent correctly.

And why would you need to test it? Because not all languages/tools work the same, you should check that the sent parameters and format are correct. Remember that, by default, browsers send content type as application/x-www-form-urlencoded. But many sites will expect JSON content, for which you’ll need to add a customer header: Content-Type: application/json.

Even if you write the same code, the result will depend on whether you add that header.
