Payment gateway lock-in sources: 1) Stored card authorization codes — not exportable, customers must re-enter card data. 2) Subscription codes — gateway-specific, cannot transfer active subscriptions. 3) Settlement account history — your financial records reference gateway transaction IDs that only make sense on that gateway. 4) Webhook event format — each gateway has different event names and payload shapes; your handlers are gateway-specific. Reducing lock-in: abstraction layer for checkout (portable), export transaction history regularly (portability for records), design subscription cancellation flow so customers can re-enroll on a new gateway easily.
| Lock-In Source | Portability | Mitigation |
|---|---|---|
| Stored card tokens (authorization_code) | Zero — not exportable | Accept re-entry cost on migration; minimize stored-card use if you expect to migrate |
| Active subscription codes | Zero — not portable | Natural decay (cancel + re-enroll on new gateway) or run two gateways indefinitely |
| Webhook handler code | Medium — rewrite per gateway | Abstraction layer normalizes event format; only adapter needs rewriting |
| Transaction history | High — if you export it | Scheduled export to your DB: GET /transaction, paginate all records, store locally |
| Settlement records | High — with export | Download settlement CSVs regularly; Paystack exports via dashboard and API |
| Checkout UI code | High | Use abstraction layer; swap adapter |
| Accounting integrations | Medium | Abstract at the data level (amount, reference, date) not at the gateway API level |
