Shopify Payment Gateway Plugin Development

@mascotindia123

Hi, I can develop a production-ready Shopify payment gateway app/plugin to integrate your system with the EasyKash API and prepare it for Shopify App Store submission. The solution will be built as a proper Shopify public app (not a simple theme-level integration), using modern Shopify App Bridge and OAuth flow so it can be reused across multiple merchant stores. I will implement secure server-side handling of payment requests, webhook verification, and checkout redirection in compliance with Shopify’s payment app requirements. The EasyKash API will be integrated cleanly with proper error handling, logging, and retry mechanisms to ensure stable transaction processing. I can also provide a dedicated Shopify development store for testing and validation throughout the build process. Once completed, I will prepare full technical documentation covering installation, configuration, API flow, and deployment steps required for App Store review. The final delivery will include a scalable, reusable architecture so the same plugin can be deployed across multiple Shopify stores with minimal setup. I have experience building Shopify apps and API integrations and can align the implementation with Shopify’s review standards for approval. Warm regards, Harpreet Singh

I can build your Shopify payment gateway app as a proper Shopify-listed plugin, not a website build. I’ve integrated custom payment gateways into Shopify apps before, and I understand the requirements for App Store readiness, repeated merchant deployments, and clean documentation. What makes me a fit for this project: - Shopify app development with payment gateway/API integration - Experience structuring apps for reuse across multiple storefronts - Ability to deliver a test Shopify store, setup guide, and full technical documentation For EasyKash, I would review the API flow, implement secure payment initiation/verification, handle callbacks/webhooks, and ensure the checkout experience follows Shopify’s app and payment requirements. I can develop the app in the right stack for Shopify, test it on a dedicated Shopify store, and provide documentation for installation, configuration, and maintenance. I’ve worked on API-driven integrations where reliability, security, and clear merchant onboarding were critical. My focus will be on a stable, reusable plugin that can be deployed across different stores with minimal setup. If you’d like, I can outline the exact implementation plan and milestones for the EasyKash integration.

Custom Plugin Expert, __ I’m an experienced Shopify plugin developer & can build a custom payment gateway plugin integrating the EasyKash API according to Shopify standards. I will develop the app so it can be listed on the Shopify App Store, Support multiple store integrations, & provide a test Shopify environment for validation. -- Regards, Ravi s.

@VianRey1

Building a Shopify payment gateway plugin that meets official app store standards can be overwhelming, especially when you need it to connect smoothly with a local provider like EasyKash. The frustration of not finding a reliable plugin developer often leads to lost time and limits how many stores you can support. You can expect an official Shopify plugin that connects any store to EasyKash, is easy to test, and comes with clear documentation for every future integration. First, I’ll study the EasyKash API documentation to ensure everything aligns with Shopify’s requirements. Next, I’ll build and test the plugin on a dedicated Shopify site. Finally, I’ll create complete documentation so you and your team can reuse the plugin across different stores. Which Shopify store should I use for the initial testing phase?

Hi, I understand you’re specifically looking for a Shopify payment app/plugin developer (not a store builder), and I have experience building custom Shopify apps with external payment gateway integrations using Shopify’s Admin API and Payment App/Checkout Extensibility architecture. I can develop a Shopify payment plugin that integrates with the EasyKash API (based on your documentation), structured for reuse across multiple Shopify stores and compliant with Shopify App Store requirements. The solution will include secure API handling, webhook support for payment status updates, proper checkout redirection flow, and full error handling to ensure stable transactions. I will also set up a dedicated Shopify development store for testing and validation, and ensure the app is production-ready for Shopify App Store submission, including required OAuth flow, billing structure (if needed), and deployment configuration. In addition, I will provide complete technical documentation covering installation, configuration, API mapping, webhook setup, and usage instructions so other developers or merchants can easily integrate it into their stores. With strong experience in Shopify app development and payment gateway integrations, I can deliver a secure, scalable, and reusable plugin architecture aligned with Shopify’s latest standards. With 8+ years of experience, I’m confident I can deliver quality work on your project. Thanks & Regards Sushma S.

@johnallenvillan1

Hello, I noticed your requirement for a Shopify payment gateway plugin that must be published as an official Shopify App and integrate with EasyKash’s API. I’ve built and delivered similar payment apps for regulated gateways, including one that passed Shopify’s app review after optimizing its OAuth flow and webhook security. I know the real challenge here is ensuring the app meets Shopify’s strict approval standards, especially around PCI compliance, redirect handling, and app listing requirements. Many developers focus only on API calls, but the review process and secure checkout extension are what actually determine success. I will build a standalone payment app using Shopify’s Payments App Extensions, implement EasyKash’s API endpoints, and prepare full documentation. I’ll also set up a dedicated Shopify test store so you can verify transactions end‑to‑end before submission. Before starting, I need to confirm a few items: whether you already have merchant API credentials from EasyKash, your expected transaction flow, and whether recurring payments will be required. This can be delivered in a clean, review-ready package. Sincerely, John allen.
