e-commerce marketplace like eBay. Depending on the user role,
merchants and shoppers will get access to different functionality.

products and register only when they want to make purchases.
It is also crucial to offer multiple ways to sign in/up, for
example, via phone, email, Google account, and social networks
(Facebook, LinkedIn, Twitter, etc.). Thanks to this, you will manage
to attract a larger audience and improve user engagement.

To reach a larger audience and increase the conversion rate, you
should offer a number of payment options. In order to implement this
comprehensive e-commerce marketplace functionality, software
developers can integrate a
payment gateway API,
for instance, PayPal, Stripe, Authorize.net, Braintree, or Square.
Serving as an analog of a virtual third-party terminal, a gateway
solution allows for verifying customer identity and processing
transactions. What’s more, a gateway protects parties against
various issues, including insufficient funds on user accounts,
expired cards, and fraud.
By using the API, software engineers do not have to build this
marketplace app feature from scratch, thereby saving you time and
costs. A gateway system also lets you connect numerous payment
methods and ensure the support for dozens of currencies.
As an example, Stripe can enable you to incorporate a range of
payment options that involve:
cards (Visa, Mastercard, Discover, JCB, Diners Club, China
UnionPay, and American Express)
electronic wallets (Apple Pay, Google Pay)
local online payment options (SOFORT, iDeal, eps, Bancontact,
Afterpay, and GiroPay)
It is worth noting that trusted gateways are compliant with the
Payment Card Industry Data Security Standard (PCI DSS), which
requires companies operating with the credit card information to
safeguard sensitive data and ensure payment account safety.
In addition, you can incorporate online payment methods such as
WebMoney and QIWI.
