About SlipOK
SlipOK is a Bangkok-based API service that combines AI with OCR to read and verify Thai bank-transfer slips, checking QR code data, font style, bank logo, amount, and reference code against real-time records from the Bank of Thailand to catch fake or duplicate slips. Merchants receive slips via LINE OA, Facebook, or a direct API integration, and SlipOK connects to Shopee, Lazada, and JD Central storefronts and to KBank's API for automated payment confirmation, replacing manual slip checking for small and medium businesses.
Key Features
Best For
Southeast Asia Fit
SlipOK is built entirely around a Thailand-specific payment behavior: buyers transferring via PromptPay and sending a screenshot of the bank slip as proof of payment, a pattern most global payment-verification tools do not address. It verifies slips in real time against Bank of Thailand records and connects to LINE OA, the dominant Thai messaging channel, and to Shopee, Lazada, and JD Central. It has no evidence of operating outside Thailand or supporting non-Thai payment rails such as QRIS or GCash.
