Senior Shopify App Developer

Budget: 27000 PLN Deadline: 19 days

Hello!

Your project interests us primarily because the main challenge here is not to write the functionality, but to build a Shopify app that will easily pass moderation and be ready for scaling.

We have a good understanding of Shopify's requirements regarding OAuth, Billing API, GraphQL Admin API, App Bridge, Polaris, Webhooks, Theme App Extensions, and the App Review process. These are the stages where problems often arise, so we lay the architecture according to Shopify's recommendations from the start to avoid rejections during moderation.

We propose to start with an audit of the requirements and architectural design, after which we will gradually implement the integration with your REST API, billing system, authentication, embedded interface, and fully prepare the application for publication in the Shopify App Store with support until final approval.

Our portfolio: https://winbixai.com/uk. The website does not showcase all completed projects, as some of them are under NDA. We would be happy to send additional cases related to Shopify, eCommerce, and corporate platforms in personal messages.

We would be glad to discuss the details and offer the optimal technical solution for your product. Expand

Good day, I can take on the development of a public embedded Shopify app with integration of your REST API and support until full approval in the App Store.
In brief: it is important to correctly set up OAuth, scopes, webhooks, and Billing API to avoid delays during the review.
A small technical nuance: incorrect scopes or subscription setups often become the reason for rejection during the review.
Please let me know what billing model you plan, whether the REST API documentation and the list of required webhooks are ready, and if you need help with the submission to the App Store and processing moderation feedback.
If you want, send access to the Partners account and test API data after your response, I will review and provide a short list of required permissions for the app review.

Good day. I am ready to bring your public embedded application to production and guide it through App Store moderation. The key right now is correct authentication with the required scopes, reliable implementation of subscriptions, and stable handling of webhooks before approval. One important technical nuance: it is necessary to clearly separate online and offline tokens and their storage; otherwise, blockers may arise during the review regarding billing and webhook authorization. I can promptly process the moderation feedback and prepare the application for resubmission. Do you have a Partner account and access to the repository so I can check the current state of the code?

Task for a public embedded application: OAuth with scopes, App Bridge, and Polaris on the front end, Billing API for subscriptions, webhooks, and integration with your REST API via a Remix backend.

I will do it in React + TypeScript, aiming for App Store moderation approval without unnecessary iterations.

I can show the ready framework in 3 days. Could you let me know if the pricing plans for the Billing API have already been defined, or do they still need to be thought out?
