paypal web hook verification in php for woocommerce plugin

[nafid]

i have developed a plugin for woocommerce for the integration paypal and its working fine, now i want to give webhook support to my plugin so that delayed payments works more efficiently.  

I have referred the doc of paypal , for the verification they have given the example of curl which is not working  for me. is it possible to do verification with in build functions instead. 
also i would like to know that if we given a false request to "api-m.sandbox.paypal.com/v1/notifications/verify-webhook-signature"

for verification what will be the response from there side

Good day @nafid 

Thank you for posting to the PayPal community.

Yes, PHP can be utilized for webhook verification.

For more information, kindly refer to the provided detailed guide links below.

I would suggest to please contact your website developer (or) the support of the third-party platform (WooCommerce) to handle the internal website code.

If you send a false or incorrect request for verification, the response will indicate that the webhook signature is invalid. This response will likely include an error message or a status code indicating the failure of the signature verification.

If your still facing issues, please create an MTS ticket via -  https://www.paypal-support.com/s/?language=en_US  with the detailed information and error details.

Sincerely,

Kavya
