Signature Validation

1. To verify the authenticity of a webhook, generate a signature using the following template:

{ID}:{MerchantID}:{ExternalID}:{Status}:{webhookPassword}

1. Hash the resulting string using the MD5 algorithm.

2. Compare the generated hash with the value received in the Signature field. Only process the webhook if the signatures match.
