How can I debug API requests for WordPress themes

1. Use the `http_api_debug` Hook:
- This hook allows you to log HTTP requests and responses to the `wp-content/debug.log` file. You can use it to debug API requests by adding a function that logs the request and response details.

2. Use the `wp_remote_request` Function:
- This function allows you to make HTTP requests and returns the response. You can use it to make API requests and debug the responses.

3. Use the `wp_remote_get` and `wp_remote_post` Functions:
- These functions allow you to make GET and POST requests, respectively. You can use them to make API requests and debug the responses.

4. Use the `curl` Command:
- You can use the `curl` command to make API requests and debug the responses.

5. Use the WordPress REST API:
- The WordPress REST API provides a unified interface for accessing WordPress data. You can use it to make API requests and debug the responses.

Here is an example of how you can use the `http_api_debug` hook to debug API requests:

php
add_action( 'http_api_debug', 'viper_http_api_debug', 10, 5 );
function viper_http_api_debug( $response, $type, $class, $args, $url ) {
    error_log( 'Request URL: ' . var_export( $url, true ) );
    error_log( 'Request Args: ' . var_export( $args, true ) );
    error_log( 'Request Response : ' . var_export( $response, true ) );
}

This code logs the request URL, request arguments, and response details to the `wp-content/debug.log` file.
