How this template works
APIs Selection
The template uses API selection filters to specify the criteria for selecting the API requests to be executed. It filters requests based on the response code being between 200 and 300, or if the request payload or query parameter contains the word "captcha" and extracts the value of the "captcha_key" parameter.
Execute request
The template defines a single request to be executed. It includes deleting the "captcha_key" from both the request body and query parameters, and adding a header "x-forwarded-for" with the value "127.0.0.1". This is done to bypass captcha protection by manipulating headers.
Validation
After executing the request, the template validates the response. It checks that the response code is between 200 and 300, the percentage match of the response payload is greater than 80%, and the length of the response is greater than 0. These validation criteria ensure that the request was successful and the response contains the expected data.
