Validate GET status of a url for mailchimp - php

Question

I have created a function that creates a batch webhook in mailchimp so that a callback will be submitted once the batch operations is finished. like following:
// register mailchimp batch webhook
$responseWH = wp_remote_post( 'https://' . substr($mcApi,strpos($mcApi,'-')+1) . '.api.mailchimp.com/3.0/batch-webhooks' ,array(
'headers' => array(
'method' => 'POST',
'Authorization' => 'Basic ' . base64_encode( 'user:'. $mcApi )
),
'body' => json_encode(array(
'url' => 'http://90660d72b8be.ngrok.io/wp-json/lubuvna/v2/batch/2810471250791421617231098394447326550803'
))
));
above code means, when a batch operation is finished MC should call this url:
http://90660d72b8be.ngrok.io/wp-json/lubuvna/v2/batch/2810471250791421617231098394447326550803
If this url is called, then a script will run and notify me that the operation is done und update the the post in wordpress.
but since the header status code is 404, mailchimp is not adding the url to the batch webhook.. instead i get following error:
{
"type": "http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/",
"title": "Invalid Resource",
"status": 400,
"detail": "The resource submitted could not be validated. For field-specific details, see the 'errors' array.",
"instance": "05a4430f-c68f-46a5-82af-3b95332d6fe83",
"errors": [
{
"field": "url",
"message": "We couldn't verify the URL is working. Please double check and try again. HTTP Code: 500"
}
]
}
How can i return a 200 status in the header when Mailchimp is trying to make a GET request to the specified URL, while adding the batch webhook? they need a valid url. mailchimp batch webhook
I am using ngrok for connection within localhost which works when i add a URL like http://90660d72b8be.ngrok.io/wp-content/plugins/my-plugin/inc/batch/import.php, because the file actually exist in the plugin directory
but when adding the URL http://90660d72b8be.ngrok.io/wp-json/lubuvna/v2/batch/2810471250791421617231098394447326550803
I can see that mailchimp makes a get request and the code status is 404 like in the screenshot

I hav ended up using follwoing:
function myplugin_registered_rest_routes() {
// batch operation finished
register_rest_route('myplugin/v2', '/batch/(?P<id>\d+)',
array(
array('methods' => ['POST', 'GET'],
'callback' => 'my_awesome_func'
)
)
);
}
add_action( 'rest_api_init', 'myplugin_registered_rest_routes' );
another option of array like #04FS answer:
register_rest_route('myplugin/v2', '/batch/(?P<id>\d+)',
array(
array('methods' => 'GET',
'callback' => 'my_awesome_func',
),
array('methods' => 'POST',
'callback' => 'my_awesome_func'
)
)
);
Another option parsing the url request. Not common when using wordpress API:
add_action('parse_request', 'register_endpoint', 0);
function register_endpoint() {
global $wp;
if ($wp->request == 'wp-json/myplugin/v2/batch/2810471250791421617231098394447326550803') {
header("HTTP/1.1 200 OK");
exit;
}
}
