Getting Started

What is WebPAY

Interswitch WebPAY Payment Page is a simple page that can be called from any website seeking to offer visitors the facility to pay for goods or services by their bank issued cards or other payment tokens.



It is designed for merchants who use shopping carts, have little experience in server side scripting, or who use shared web servers that do not offer secure database services.

Interswitch WebPAY Payment Page is easily integrated with most of the major shopping carts.

With just a few lines of code, the merchant’s website can be ready to accept payment.



There is a one-time integration fee of N150,000 and for every subsequent successful transaction, a fee of 1.5% of the value of the transaction subject to a cap of N2,000 is charged. (i.e. for transactions below N133,333, a fee of 1.5% applies), and N2,000 flat fee (for transactions above N133,333).



WebPAYDirect is a secure Internet Payment Gateway developed by InterSwitch to facilitate payments on the internet (across all Banks) using all InterSwitch enabled Cards issued by all banks on the network as well as GTB MasterCard Naira Debit.

Heads up!

You will be required to pay a one-off fee N1.5 million for WebPAYDirect and subsequent 1.5%  fee per transaction (for transactions below N133,333) and N2000 flat fee (for transactions above N133,333)

Cardholder security

Cardholder is security is ensured by two approaches. PIN encryption and translation; and cardholder data encryption.

PIN encryption and translation involves encrypting the cardholder PIN all the way from the card accepting device (or terminal) and translating it across the different security zones between the entities using hardware security modules (HSMs). During this process, the PIN is never in the clear inside any application software and therefore cannot be compromised. All encryption and translation is carried out in the most secure part of the HSMs.

Payment Card Industry’s Data Security Standards (PCI DSS) require that payment processors “protect stored cardholder data”. That means that all cardholder information such as the numbers printed on either side of the card and is contained in electronic format in the magnetic strip embedded in the back side of the card or inside the chip must be protected using the strongest cryptographic methods. The Interswitch payment platform is currently PCI DSS certified and Interswitch Limited is also a member of the PCI council.
