You can configure HTTP Basic authentication for your webhook endpoint by providing a username and password as
username:password. This will be included in the header of the request when it's sent to your server.
To verify that the webhook message originated from Envoy, a signature header
X-Envoy-Signature is included in each webhook message. This signature is a Base64-encoded string that represents a SHA-256 HMAC of the request body, using your app's client secret as the key.
You can validate the signature by building your own signature of the request body signed with your client secret and comparing the two signatures. If the signature does not match you should reject the request.
All of the official Envoy SDKs verify signatures automatically.
OpenSSL::HMAC.hexdigest (OpenSSL::Digest::Digest.new ('sha256'), api_key, '%s%s' % [timestamp, token])
Envoy has retry logic to resend a webhook if a successful response (2xx) is not returned by your server. Webhooks are retried 5 times over the span of 10 minutes.
