FluentCart v1.3.0: PayStack, REST API and Security Audit

At FluentCart, we’ve always promised one thing: we’ll keep evolving exactly the way our users need us to. Your feedback shapes our roadmap, your challenges guide our improvements, and your growth pushes us to build faster, smarter, and better.

And today, we’re excited to deliver on that promise once again.

FluentCart v1.3.0 is here with a brand-new payment gateway, lots of new improvements, features, a security audit by Patchstack, and fixes that make your store smoother, safer, and more reliable than ever.

Let’s dive into what’s new under the hood.

Introducing Paystack Payment Gateway

We’ve expanded payment options and made checkout more flexible for both store owners and customers.

Accept payments across Africa with one of the continent’s leading payment processors!

This new payment gateway is available as a free add-on. It supports normal payments as well as subscriptions.

Introducing REST API Doc

Within just one month of FluentCart’s release, lots of developers started working to extend FluentCart. We have many integrations live already from 3rd party developers. To make it easier for 3rd party developers, we have released the dev docs as well as releasing REST API docs and REST API playground to make it easier to explore and build solutions on top of FluentCart.

New Subscription Intervals

Added Quarterly and Half Yearly Subscription intervals options – You can now add Quarter and Half-year intervals to all your subscription products. This means it’s now easier to sell subscriptions for 3 months and 6 months alongside your Annual and Monthly plans.

Security & Compliance First

We take your store’s security seriously. Earlier this month, we contacted Patchstack, and we purchased their comprehensive Full plugin security Audit Service. Patchstack is one of the most trusted security companies for WordPress, and we got in detailed audit report, improvements. Our team implemented all the suggestions made by the Audit Report and we are committed to continuing security improvements as an ongoing effort.

Coupon Module Improvements

You can now restrict a coupon by a customer’s email address or domain. Imagine, you can give a special coupon to a partner company by something like *@partnercompany.com. Now you can do this, and the feature is built right into its core.
