Fix Shopify App Billing Integration

@rajat07me

I’ve worked on Shopify app integrations and billing-related flows, so your brief is clear to me. The key here is usually a mix of app configuration, callback handling, approval URL flow, and webhook logic all needing to align properly. I can trace the failure point, fix the one-time charge process, and make sure the charge status is recorded cleanly on your side. I’ll also leave a concise handoff note so your team can maintain the fix easily.

Hi, I will fix your one-time charge flow so the Billing API creates the charge, redirects the merchant to Shopify's confirmation screen, and records the status back on your platform without triggering any recurring billing webhooks. On a similar Shopify app fix, the root cause turned out to be a mismatched callback URL between the app setup and the charge creation request. I will check yours first since that is the most common culprit. Questions: 1) Is the app built with Node/Express, Rails, or another stack? 2) Are you seeing specific error codes from Shopify's response, or just silent failures on the confirmation redirect? Share the repo access and test store credentials and I will run the first diagnostic today. Looking forward to potentially working together. Thanks, Kamran

I can help with this Shopify billing issue. From your description, this sounds less like a platform limitation and more like a flow/configuration mismatch between charge creation, approval callback, and webhook handling. I’ll debug the existing setup, correct the one-time billing implementation, and make sure the merchant sees the right confirmation flow without recurring-charge confusion. I can also provide a short code-location note for your internal team at the end.

@mahig47

Hello, I've carefully reviewed your Shopify Billing API issue and understand that the Shopify store connection and data synchronization are already working correctly. The remaining blocker is the one-time Billing API flow, where charge creation, merchant approval, callback handling, and unexpected recurring billing behavior are preventing a successful production-ready implementation. I have experience working with Shopify apps, OAuth authentication, Admin APIs, App Bridge, and the Shopify Billing API. I can thoroughly debug the existing implementation, identify any issues with app configuration, callback URLs, embedded app redirects, API version compatibility, or billing permissions, and implement a fully compliant one-time charge flow. I'll also verify webhook handling to ensure duplicate events or recurring billing logic cannot trigger unintended charges, while correctly recording the final payment status within your SaaS platform. The deliverables will include the complete fix, tested on your Shopify development store, clean and well-documented code, a successful end-to-end billing flow from charge creation through merchant approval, and a short Loom/video walkthrough explaining exactly what was changed so your team can maintain it confidently. I also provide 3 months of free post-delivery support for any billing-related issues or minor refinements. PLEASE INITIATE CHAT SO I CAN SHARE MY PREVIOUS SHOPIFY WORK. Best Regards, Nikita Gupta Questions:

I have read your job post. I am a Full Stack Developer with experience building Shopify public/private apps, Shopify Admin APIs, Billing API integrations, OAuth authentication, and embedded SaaS applications using Node.js, React, Laravel, and Shopify App Bridge. I have worked on diagnosing app review issues, fixing billing workflows, and ensuring Shopify billing complies with their latest API requirements. I can audit your existing Billing API implementation, identify why the one-time charge creation is failing, verify app configuration, callback URLs, OAuth scopes, and API version compatibility, then implement a reliable one-time billing flow that correctly redirects merchants to Shopify's approval screen, records the payment status, and prevents duplicate charges or unnecessary recurring billing events. I'll also document the changes with a concise hand-off guide (or Loom video) so your team can easily maintain the integration going forward.

@PINESCRIPTERR

Hi, I can audit and repair the Shopify one-time billing flow without touching the working store-sync functionality. I’ll trace the complete sequence from charge creation through merchant approval, return URL validation, status verification, and persistence in your SaaS database. The review will cover app configuration, scopes, shop/session handling, callback URLs, test-mode settings, API-version compatibility, and any mismatch between REST and GraphQL billing implementations. I’ll implement a compliant one-time purchase flow that presents Shopify’s confirmation screen, verifies the approved charge server-side, and stores a clear pending/approved/declined/cancelled state. Idempotency controls and transaction-level locking will prevent duplicate charges or repeated callback processing. I’ll also inspect the subscription-style webhooks currently arriving, identify why they are being triggered, and add verified, deduplicated webhook handling so they cannot create billing side effects. Testing will include approval, cancellation, callback retries, expired sessions, duplicate webhooks, and app reinstall scenarios. Delivery includes the code fix, a successful test-store charge, reproducible test steps, and concise hand-off notes or a Loom walkthrough. Question 1: Is the current app public, custom, or distributed through Shopify’s App Store? Question 2: Is billing currently implemented through REST charges or GraphQL mutations? Regards, Houssame

@Hrolgar

Data sync working but billing broken almost always means the charge creation call to AppPurchaseOneTimeCreate never gets its confirmationUrl handoff stored properly, or the return_url callback isn't verifying charge status against Shopify before writing to your SaaS. That double-charge risk usually comes from the callback firing twice, once on the redirect and once on a webhook event, with nothing checking whether the charge is already ACTIVE before a second write happens. I'd start with an audit of your app config, the charge creation call, and the callback route, mapping exactly where status gets recorded today and where it silently drops. Then rebuild the charge path as a compliant one-time purchase flow, add a return_url handler that verifies state against Shopify's Billing API before touching your SaaS, and make the webhook handling idempotent so a retried callback or duplicate event can't create a second charge. M1: audit and diagnose config, charge creation, callback route, exact failure points mapped, 21000 INR, 1 day. M2: rebuild charge creation and callback verification flow, 21000 INR, 1 day. M3: idempotent webhook handling, repeatable test-store charge, handoff note or Loom, 21750 INR, 1 day. Is the charge strictly one-time, or does the SaaS need recurring or usage-based billing down the line too?

After reading through your project description, I must say, I am excited by the challenge it presents and I believe I am perfectly poised to deliver the results you need. Over the years, I have honed my skills in fixing intricate issues like what you are currently experiencing - ensuring platforms and integrations run optimally and adhere to strict CPA compliance regulations. I have a deep understanding of Shopify's Billing API and can swiftly diagnose errors within code, identify configuration inconsistencies, and remedy them efficiently. Furthermore, my approach centers around effective communication and long-term solution scalability. In line with this philosophy, I will provide you with not just an initial fix but also a comprehensive hand-off note (possibly through loom) detailing where the fix lies in the codebase so your team can easily maintain it in the future. With access to your repo, existing Billing API code, and a test store, I will prioritize getting that first successful charge through replicate it for the rest of your stores. Let's work together to resolve these billing integration challenges for good!

One-time charges through Shopify's Billing API are deceptively simple until you hit the callback URL mismatch or the charge object gets created with the wrong `test` flag on a development store. That's usually where "setup errors" and approval failures originate. I'll trace the exact failure point in your existing charge creation flow, fix the callback/redirect configuration, and wire up a compliant one-time charge cycle that surfaces Shopify's native confirmation screen and writes the charge status back to your SaaS. For the recurring-billing webhooks firing unexpectedly, I've seen this happen when the app scopes include `read_charges` alongside subscription-related permissions. I'll audit the scopes and add idempotent webhook handling so duplicate or irrelevant billing events don't trigger any merchant-facing charges. Best regards, Shayan

@techsty2014

This looks like a great fit, We will diagnose your Billing API failures and deliver a working one-time charge flow that passes Shopify approval on your test store. The most common cause here is a mismatch between the charge callback URL and the app's allowed redirection URLs in the Partner Dashboard. We will trace that first, then verify your API version and charge object parameters. For the unwanted recurring webhooks, we will filter those at the handler level so merchants never see a double charge. A couple of quick things to confirm: 1) Which Shopify API version is your app currently using (e.g., 2024-01, 2025-01)? 2) Is the app built with Node/Express, Rails, or another stack? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Ready to start whenever you are. Faizan

@sufyanaslamch

Hello Sir, I have carefully read your requirements and can diagnose and fix the Shopify Billing API issues in your existing connector app. I understand that the store connection and data sync already work, so I will focus only on the one-time charge flow, approval redirects, callback handling, charge-status recording, and duplicate billing protection. The work will include: • Review of the current Billing API implementation • Identification of app setup, callback, or permission issues • Correct one-time charge creation and merchant approval flow • Reliable return URL and charge-status verification • Storage of approved, declined, or cancelled charge results • Handling of unexpected recurring-billing webhooks • Duplicate-charge and repeated-callback prevention • Testing on your Shopify development store • Clear handover notes or Loom walkthrough I have experience with Shopify app authentication, Admin APIs, billing flows, webhooks, session handling, and third-party SaaS integrations. I will consider the work complete once the first charge is approved successfully, recorded correctly in your platform, and the same process can be repeated without errors or double charging. I am waiting for your kind response. Thanks

@tyronet2

You need to fix a Shopify app Billing API flow where one-time charges fail, incorrect billing behavior appears, and merchants are not getting a reliable approval experience. I have experience building ecommerce platforms, payment integrations, API workflows, and backend systems that handle transactions and external service communication. At Poundit Inc, I worked on ecommerce systems with payment flows, backend integrations, and automated business processes. I can review your Shopify app code, trace the Billing API setup, validate app configuration and callback handling, and implement a clean one-time charge flow. I will check why recurring billing events are appearing, prevent duplicate charge scenarios, and make sure charge status synchronization between Shopify and your SaaS platform works correctly. My approach will be to reproduce the issue using the test store, fix the billing logic, verify the approval flow, and provide clear hand-off notes explaining the changes.
