| 12 | * documented v1.2.0-beta flow (grant token -> create payment -> customer |
| 13 | * redirected to bkashURL -> execute payment on return). bKash has revised |
| 14 | * this API's version path before — confirm the base URL against the |
| 15 | * operator's current merchant onboarding docs and run a real sandbox |
| 16 | * transaction before enabling this live; this has not been tested against |
| 17 | * a live bKash sandbox. |
