Gateway Transaction ID Cloaking
Budget: £20 – £250 GBP
I need a clean, reliable way to stop real transaction identifiers from ever reaching the customer side of my checkout flow. The top priority is PayPal: every PayPal Transaction ID must be swapped for an internal token before it appears in a browser response, confirmation email, or third-party script.
Because I also process some payments through Stripe, I want the same protection there, but only for transaction details—specifically the Stripe Transaction ID. Merchant and customer data can stay exactly as is.
The workflow I picture is straightforward:
1. Payment request is made.
2. Your middleware (language is your choice) intercepts the gateway response.
3. The live Transaction ID is replaced with a hashed or otherwise obfuscated value.
4. The real ID is written to my database so I can reconcile, refund, or dispute without friction.
5. All other functionality—webhooks, payouts, dispute handling—continues to work untouched inside PayPal and Stripe.
Deliverables
• Production-ready, well-commented source code that plugs into both PayPal’s REST API and Stripe’s API/webhooks to perform the cloaking.
• Lightweight schema or config file mapping hashed IDs to the originals.
• Step-by-step deployment guide for a standard Linux stack.
• Test plan proving a sandbox payment shows only the masked ID client-side while the true ID remains visible in each gateway’s dashboard.
Acceptance Criteria: a live sandbox purchase on both gateways completes successfully; browser network logs, customer emails, and webhook payloads expose only the masked ID; I can retrieve the true ID on demand from the stored mapping.
Let me know how you would structure the middleware layer and your estimated turnaround time.
