Webhook Signature Verification

• Header: X-Simiz-Signature
• Format: t={timestamp},v1={signature}
• Algorithm: HMAC-SHA256 of {timestamp}.{payload} using your webhook secret
• Tolerance: 300 seconds (5 minutes)

​

Test Mode

1. Set the provider state to Test Mode in Odoo
2. Use your sandbox API key (smz_test_*)
3. The module will automatically use the sandbox API endpoint
4. Create a test sales order and proceed to payment
