Hello, Your BigCommerce app and integration issues point to a deeper problem: the store is likely losing conversions at the transaction layer, not just showing isolated bugs. I’ve handled payment and platform integration fixes across PHP, API, and eCommerce workflows, so I can trace where the payment flow or social integration is breaking and stabilize it cleanly. I’ll review the app logic, payment gateway behavior, and integration callbacks/webhooks, then map a clear fix plan before changing anything critical. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Which exact integration flow is failing most often: checkout, webhook callback, or post-authorization sync? I’ll also verify whether the issue is in the app configuration, API auth, checkout flow, or post-payment sync so we solve the actual cause, not just the symptom. Could you share which BigCommerce app/gateway is affected, and whether the failures happen at checkout, webhook callback, or after authorization? Are the social/platform integrations using native connectors or custom API endpoints? Do you have error logs or a recent change that may have triggered the issue? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

I can start immediately by tracing the BigCommerce app and integration issues from the storefront through API requests, checkout, gateway responses, and webhook callbacks. I’ll first reproduce the failed transaction, inspect browser/server logs and BigCommerce configuration, then isolate whether the problem is caused by app permissions, API authentication, checkout settings, payment-gateway handling, or an integration-side error. For payment processing, I’ll verify checkout and order status flows, validate request/response handling, and fix any PHP or JavaScript issues preventing successful transactions. I’ll also review the social media and platform integrations, test their API callbacks and data synchronization, and correct failures in the existing implementation without disrupting working features. Where needed, I’ll use BigCommerce REST/GraphQL APIs and add clear error handling and logging so future failures are easier to identify. I’ll provide a concise resolution plan after the initial review, implement the fixes, and test successful and failed scenarios across the relevant integrations. I have 10+ years of full-stack experience and extensive background with e-commerce, payment gateways, APIs, PHP, JavaScript, and troubleshooting. Is the transaction problem limited to one payment gateway, or does it affect all available payment methods? Muhammad Saad

Hi, I'm Denis, a full-stack developer who has worked on BigCommerce integrations and payment processing systems. I understand you need to resolve issues with payment processing and social media integrations so transactions and workflows run smoothly. Payment processing problems often stem from misconfigured gateways, API timeouts, or mismatched data formats between BigCommerce and payment providers. I can review your current setup, identify where transactions are failing, and implement fixes at the gateway level or within the BigCommerce app logic. For social media integrations, I’ll check API keys, webhook configurations, and data synchronization between platforms to ensure feeds and interactions remain consistent. I’ve handled similar cases where payment failures were caused by outdated SDKs or incorrect order state management. Once we confirm the exact failure points, I’ll patch the code, test each integration thoroughly, and deploy with monitoring in place to catch regressions early. The main risks are unclear logs or undocumented third-party API changes, which can mask the real issue. I’ll add logging where needed and verify endpoints before making changes. I can start working right away. Let's connect and discuss the details. Thanks, Denis.

Hi, We’re an experienced team of BigCommerce developers and can help troubleshoot and resolve the app, payment, and third-party integration issues affecting your store. We’ll first audit the current setup, installed apps, payment configuration, API/webhook connections, and any custom scripts to identify the actual root cause rather than applying temporary fixes. We can then resolve payment transaction issues, check checkout functionality, and verify social media and other platform integrations end-to-end. We have strong experience with BigCommerce, APIs, payment gateways, custom integrations, JavaScript, and backend troubleshooting. We’ll also make sure the fixes are properly tested across desktop and mobile before considering the work complete. Two quick questions: Which payment gateway is currently failing, and do you have any specific error messages or failed transaction examples? Which social media/app integrations are currently causing issues, and are they failing completely or only for certain functions? We can start soon, review the existing setup first, and provide you with a clear action plan before making changes.

Having worked in the web development industry for over two decades, I've amassed a wealth of experience and expertise that I believe make me the ideal choice for your BigCommerce app integration project.

Specifically, on BigCommerce, my broad knowledge backed by experience enables me to leverage available tools/APIs to enhance functionality. A frequent problem is unpredictable behaviour arising from APIs not passing the expected data - I’ve seen this before. OnCollisionally making it difficult to perform some transactions which could result in costomers being lost-M sure you wouldn't want that. In addition to fixing the current issues on your platform, I am also focused on building sustainable solutions that stand the test of time as your business expands. This is to ensure you don't need a developer every other month. With your approval, I'd love to put my advanced proficiency with WooCommercê and Laravel to work so we can nip these problems efficiently on their bud. Let's get started on transforming your BigCommerce app integration woes into a pillar of strength for your e-commerce success.
