Does this support HitPay Sandbox testing?

Absolutely. It includes specific IP allowlisting and configuration details for both HitPay production and sandbox environments.

Why is signature verification necessary for webhooks?

Signature verification ensures that the webhook payload actually came from HitPay and hasn't been tampered with or spoofed by a third party.

How does this skill verify HitPay webhooks?

It implements HMAC-SHA256 signature verification by comparing the 'Hitpay-Signature' header against a hash of the raw request body using your secret salt.

Does it handle duplicate webhook notifications?

Yes, the skill includes implementation guidance for idempotent processing to ensure each payment event is only handled once.

Which web frameworks are supported?
