Hi there, I have experience integrating OpenCart 3.x stores with eBay using solutions like OpenBay Pro, official marketplace integrations, and custom API setups depending on the store requirements. I can fully configure the sync so products, inventory, and orders move reliably between OpenCart and eBay while keeping the setup stable, upgrade-safe, and easy for you to manage once your eBay store becomes active. I can handle the complete setup including product publishing with variations and images, inventory synchronization, cron/API configuration, and end-to-end order testing to ensure orders from eBay appear correctly inside your OpenCart admin. I’ll also provide simple handover notes so you can manage listings and basic troubleshooting yourself after delivery. Kindly send me a message to discuss more. Thanks

Hi, I will set up the full bidirectional sync between your OpenCart 3.x store and eBay — product listings with images/variations, live inventory counts, and order import back into your OpenCart admin. My recommendation is OpenBay Pro since it is natively supported in OpenCart 3.x and handles the eBay Trading API callbacks well. I will configure item specifics mapping per eBay category to avoid listing policy violations — a common issue when category fields do not match eBay's required item specifics, which causes silent listing failures or suppressed visibility in search. Questions: 1) Which eBay marketplace are you targeting — eBay US, UK, or another region? 2) How many SKUs and product variations will need to sync initially? Looking forward to discussing further. Best regards, Kamran

I’ve implemented OpenCart 3.x integrations with eBay using both OpenBay Pro and direct API based solutions, including bi directional sync for listings, stock levels and order imports. For your setup, I’ll configure the most stable and upgrade safe approach based on your current extensions, hosting environment and long term maintenance needs. I’ll ensure sample products publish correctly with images, categories and variations preserved, and that test eBay orders flow cleanly into OpenCart with accurate customer and payment data. The integration will be fully configured, tested and ready for launch the moment your eBay store is activated. I’ll also provide concise hand over notes covering product publishing, sync monitoring and basic troubleshooting so you can manage day to day operations confidently. Regarding inventory sync frequency, I can support near real time updates depending on the API and cron limits available on your server, but I’d like to confirm your preferred interval before final configuration.

The cutoff in your description suggests the eBay account status is blocking the API handshake. This usually happens when OAuth tokens expire or the merchant ID isn't linked correctly in the OpenCart module. I've handled several PHP based eCommerce integrations involving MySQL and external APIs. The focus here should be verifying the API credentials and ensuring the cron jobs for inventory sync are actually running. Most OpenCart 3.x eBay modules fail at the initial authentication step rather than the data sync itself. I can troubleshoot the connection logs and get the status active. Do you have a specific error message showing in the OpenCart admin panel?

I’ve connected OpenCart 3 stores to eBay before, syncing listings, inventory, and orders smoothly. The key is selecting a reliable integration—OpenBay Pro often works well for many clients, but a custom API script can offer more control if your setup is unique. I’ll start by installing and fully configuring the chosen module or script, making sure it’s licensed and ready to go. Then I’ll publish a few sample products with images, categories, and variations from your OpenCart to eBay, confirming they appear correctly. Next, I’ll set up inventory sync so stock updates on either platform reflect both ways within the expected intervals. Finally, test orders will be placed on eBay to verify they show up in your OpenCart admin with all the right customer and payment info. Do you prefer an off-the-shelf module like OpenBay Pro, or would a custom API integration better fit your needs? Also, do you have a preferred schedule or method in mind for inventory syncing (cron job vs webhook)? Once we’re done, I’ll provide clear hand-over notes so you can add products and handle common sync issues easily. Ready to get your eBay store live and fully synced.

@OscarMozo

Hi, I can help you You want your OpenCart shop and your eBay account to talk to each other. New or changed products in OpenCart should show on eBay with images and options. Stock should match in both places. Orders from eBay should appear in OpenCart with all the right details. It should be stable, safe on updates, and ready to switch on when you go live. This will take a few days, I've been doing this type of work for years. I have short walkthrough videos on my Freelancer profile showing similar work. 1) What do you have set up now in OpenCart and eBay, including any modules, categories, and product options? 2) What should the final listing layout look like on eBay, including shipping, returns, and price rules? Ideally, we have a call and go through the details together so I can make sure I understand everything correctly, address any questions, and give you a quote and timeline. Would that work? Best, Nicolas

@vladang

You’re already at the point where the risky part isn’t opening the eBay store — it’s making sure inventory and orders don’t drift once traffic starts coming in. On OpenCart 3.x, I’d first verify which integration path makes the most sense based on your catalog structure and variation complexity. If OpenBay Pro covers it cleanly, I’d rather use that than over-engineer a custom bridge, but I’ve also worked with direct API syncs when modules became unreliable after updates. The first thing I’d do is set up a controlled sync environment with a few representative products, especially variants, so category mapping, images and SKU handling are validated before the store goes live. Then I’d wire inventory + order sync through cron with logging in place, so failed API calls or duplicate order pulls are easy to trace instead of silently breaking. I’ve handled similar PHP/OpenCart integrations before where the main issue ended up being edge-case stock mismatches after partial refunds, so I usually account for that early. I can get this connected, tested and ready for launch.
