Project description:
"My Laravel-based PHP site is throwing a “Hash mismatch” error during PayU Money checkout. The payment keys and salts are in place, but the transaction halts at the hash validation step. I’d like someone who has already integrated PayU Money (not Biz or Enterprise) to step in and get the flow working.

Scope is straightforward:
• Identify why the generated hash fails against PayU’s verification.
• Adjust the hash string sequence, key/salt usage, or any required parameters in the Laravel controller, route, or view.
• Prove the fix with at least one successful test transaction in sandbox mode and share the working code snippet or commit.

You’ll receive immediate access to the relevant controller and environment variables; no other parts of the project need touching. A quick screen-share demonstration that shows the payment completing without errors is enough for acceptance." (client-provided description)
