Weepay V2 goals include simplying the procedure and shortening the time spent on the integration of the merchant site to Weepay so the merchant can immediately accept payment as soon as they are accredited.

Integration may immediately take place while merchant is being accredited by Weepay payment partners for the Online Payments.

Weepay Online V2 comes into two integration types that is based on the merchant requirement and the capability of their website.

Website Type: Dynamic

Dynamic Sites may feature (1) updated links to their product inventory; (2) requires a comprehensive computation pattern; (3) detailed Know-your-client procedure and database and (4) active Shopping Cart facility integrated to their website.

We recommend the Advance Integration (Full E-commerce)
