I removed the api_key from the query string but it still give me an error invalid parameters, even though I use the exam same as their documentation and on Postman it works.
@Windgrowth Take a look at your console in Google Chrome to see the actual API call being made. Please post this here, so we can have a look in there.
You can also try to remove as much parameters as possible, and then only try with 1 parameter. This way you can backtrack where it’s going wrong.
