Content-to-Merchant API Migration

@shayankhan333

Hi, I will re-engineer your product feed from the Google Content API to the Merchant API in Python, porting authentication, product insert/update, batch calls and error reporting, then run a full sync so every SKU matches your back-office. I can start today. For OAuth 2.0, I will handle rate limits and pagination carefully and resolve any disapproved items before hand-off. Questions: 1) How many SKUs and custom attributes are in the current feed? 2) Is the scheduling on cron, Cloud Scheduler, or something else? Looking forward to discussing further. Regards, Shayan.

Hi, I can handle the migration from Google Content API to the Google Merchant API while keeping the existing product feed reliable and data-accurate. I have experience working with **Python, REST/JSON, OAuth 2.0, Google APIs, product feeds, batch processing, rate limiting, pagination, and error handling**, including integrations that require syncing large datasets reliably. My approach would be: 1. **Audit** – Review the current Content API implementation, authentication, product attributes, batch operations, scheduling, and error handling. 2. **Migration** – Implement the Merchant API equivalent in Python, including OAuth 2.0, batching, pagination, rate limits, retries, and structured logging. 3. **Validation** – Run a complete synchronization, compare SKUs and attributes against the back-office source, identify disapproved/mismatched products, and resolve discrepancies. 4. **Handover** – Provide concise documentation covering API flows, configuration, scheduling, troubleshooting, and maintenance. I’d keep Python unless there is a clear technical benefit to switching to Node.js. Estimated timeframe: **4–7 business days**, depending on the size of the feed and complexity of the existing Content API implementation. I can start by auditing the current integration and provide a clear migration plan before making production changes.

Switching from Google Content API to Merchant API can trip on attribute validation that the old flow ignored. I'll audit the calls, map custom attributes to the Merchant schema, and use the google-api-python-client library to stay in Python. OAuth token refresh will be wrapped in a retry loop so the schedule survives Google throttling. A common pitfall is assuming a single page response; the Merchant API paginates results, so missing nextPageToken can leave half the catalog unsynced. I'll add a loop that respects the five‑request‑per‑second limit and logs any disapproved SKUs for quick review. Ready to start immediately and will leave concise hand‑off notes for your team.

The current Content API loop uses a fixed page size that can drop items when the Merchant API enforces stricter pagination. I’ll audit the Python code, map each Content call to its Merchant counterpart, and rewrite the auth flow to use OAuth 2.0 refresh tokens. You’ll receive a drop‑in script that pushes every SKU exactly as it appears in your back‑office. A common mistake is assuming the Merchant API will accept the same custom attribute names, which often triggers silent disapprovals. I’ll add a validation step that flags mismatched attributes before the batch upload, so the final sync matches the back‑office catalog without surprises.

Hi, You need your existing Google Content API product feed migrated to the Merchant API without data loss or SKU mismatches. I can audit the current Python implementation, map its authentication, product fields, batch calls, scheduling, and error handling, then rebuild the equivalent Merchant API flow. The migration will cover OAuth 2.0, pagination, rate limits, product insert/update operations, full synchronization, error handling, and validation against your back-office data. End-to-end testing and concise handover documentation will also be included. Once I review the existing Content API code and feed structure, I can confirm the migration approach and timeframe. Best regards, Akif S

Hi! I can help migrate your existing Google Content API product feed to the Merchant API while keeping the current product data and synchronization flow reliable. 1. I’ll first audit the Python implementation, documenting authentication, product insert/update calls, batch processing, custom attributes, scheduling, and current error handling. 2. I’ll then migrate the integration to Merchant API using the appropriate Google API libraries, OAuth 2.0, pagination, rate-limit handling, and robust error reporting. 3. I’ll perform a full synchronization and compare Merchant Center data against your back-office SKUs to identify mismatches, missing products, or disapproved items. 4. I’ll fix synchronization issues and provide concise handover documentation covering the new API flow and maintenance. I have experience with Python, REST/JSON APIs, OAuth authentication, API integrations, data validation, and automation. I’ll keep the implementation maintainable and avoid unnecessary changes to your existing system. Question 1: Can you provide the current Content API code and a sample of the back-office product data for the initial audit? Question 2: Are there any custom attributes or feed rules that must remain exactly unchanged during the migration? I can start with the audit and provide a clear migration plan and estimated timeframe after reviewing the existing implementation.

Having worked extensively with RESTful APIs, including Google’s API libraries, I am well-versed in the inner workings of Content and Merchant APIs. My thorough understanding of PHP, MySQL, and Node.js further complements this knowledge base. Although my specialization is not specifically in the migration you require, I have successfully completed numerous similar projects that involved working with different platforms and APIs. For this project, I would begin by conducting a detailed audit of the existing Content API implementation to thoroughly understand its unique attributes and scheduling set-up. I would then take a systematic approach to building an equivalent flow for the Merchant API, taking into consideration important factors like OAuth 2.0, rate limits, and pagination to ensure a smooth transition that doesn't compromise any dataset accuracy. Considering the complexity of this project and the importance of maintaining data integrity throughout the process, I anticipate this will be a diligent undertaking that could be completed within [estimated timeframe]. I believe my skill set and experience make me an ideal candidate for your requirement, as I bring deep knowledge about PHP, MySQL, and RESTfulAPIs combined with my meticulousness from previous projects. Looking forward to hearing from you soon!

Hello, I’m a Senior Full-Stack Developer experienced with Python, REST APIs, OAuth 2.0, JSON, Google APIs, data synchronization, and production integrations. I can audit your existing Content API implementation and migrate the feed to the Google Merchant API while preserving SKU accuracy and business data. My approach: Audit the current Content API calls, authentication, custom attributes, batching, scheduling, and error handling. Rebuild the integration using the Merchant API with OAuth 2.0, pagination, rate-limit handling, retries, and robust error reporting. Keep Python unless there is a clear technical advantage to another stack. Run a complete synchronization and compare Merchant Center data against your back-office source to identify discrepancies. Investigate and resolve rejected/disapproved products where caused by the integration. Provide concise documentation covering API configuration, synchronization, error handling, and maintenance. I have strong experience building API-driven integrations and data synchronization systems, including authentication, third-party APIs, webhooks, batch processing, and production troubleshooting. Estimated timeframe: 3–5 business days, depending on the complexity of the existing Content API implementation and number of SKUs. I can start by reviewing the current integration and producing a short migration plan before making production changes. Best regards, Michel

I've completed three Google Merchant Center integrations in the past 18 months, including a Content API to Feeds API transition for an e-commerce platform with 50K+ SKUs. My approach: (1) I'll audit your current Content API implementation, document all custom attributes and scheduling dependencies, then map them to Merchant API equivalents. (2) Build the OAuth 2.0 flow with rate-limit handling and pagination, migrate your dataset in batches with checksum validation to guarantee zero data loss. (3) Run full sync tests, identify and resolve disapproved items, deliver comprehensive runbooks and monitoring setup so your team maintains it independently. I'll stick with Python unless you prefer Node for specific performance gains, which I don't see here. Expected timeline is 12-14 days for full delivery including testing and documentation.

Hi, I can migrate your feed from the legacy Google API to the Merchant API in Python while ensuring zero data loss across your SKU catalog. Must clarify I've yet to work on these kinds of projects. My Approach (mostly 2-3 days of working): ->Audit & Mapping: Map your current Content API batch calls, payload schemas, and custom attributes to the Merchant API products resource. ->Build & Optimize: Update authentication (OAuth 2.0 / Service Account) and port batch upsert routines with exponential backoff for quota management. ->Validation: Reconcile all live SKUs against back-office data, fix disapprovals, and deliver clear hand-off documentation. Ready to review your existing codebase and begin immediately.

Hello, I can help migrate your existing Google Content API product-feed integration to the Google Merchant API while keeping the existing product data and back-office workflow intact. I will first audit the current Python implementation, document the existing API calls, authentication flow, product attributes, batch operations, scheduling, and error handling. I will then map these requirements to the Merchant API and implement the equivalent integration with OAuth 2.0, pagination, rate-limit handling, retries, and proper error reporting. After implementation, I will perform an end-to-end synchronisation and compare the Merchant Center data against your back-office records to verify that every SKU, attribute, price, and relevant product field is transferred correctly. Any API errors or product disapprovals identified during testing will be investigated and resolved where they are caused by the integration. I can continue with Python to minimise unnecessary changes to your existing codebase, unless there is a clear technical advantage to using Node.js. I will also provide concise hand-off documentation covering the new API flow and maintenance requirements. I am available to start immediately and can complete the migration and testing within a focused development cycle. Best regards, Sugam

@bohdanmelnykua

Hi! I've handled OAuth-based Google API integrations before, including batch product syncs with rate-limit and pagination handling. I'd start with a quick audit of the current Content API calls and custom attributes, then port the auth and batch logic to Merchant API and validate everything with a full sync against your back-office data. Is the current setup on the legacy Content API v2.1, or a mix of versions I should check first?

@ladoborton

Hi — I've done exactly this migration before: moving Google Content API product feeds onto the new Merchant API, with all the auth, sync and error-handling rebuilt from scratch. How I'd approach your three steps: 1. Audit the current Content API code — map every call, custom attribute and scheduled job so nothing gets lost. 2. Rebuild on Merchant API — OAuth 2.0 flow, proper handling of rate limits and pagination, then migrate the dataset with a dry-run first so there's zero data loss. 3. Prove accuracy — full sync, reconcile every SKU against your back-office, catch and fix any disapproved items, and hand over clean maintenance notes for your team. I work in Node.js and Python, so I can keep your current Python code or port it to Node — whichever gives you the cleaner long-term result. Strong background in REST/JSON and Google's official API client libraries. Estimated timeframe: 4–6 working days depending on how many custom attributes the current feed uses. One question to scope it precisely: roughly how many SKUs and custom attributes are in the feed today? Happy to start with the audit so you can see the plan before committing to the full build.
