Hello everyone, I submitted an application for an API limit increase (Compatible Application Check) for my application, but it has been stuck in "In Progress" status for quite some time now with no updates from the eBay Developer Support team. Our application is currently ready for production, but the default limit of 5,000 calls/day is too restrictive for our merchant synchronization and automated optimization workflow. Here are a few details: Submission Date: [June 24 2026, 1:14:42 AM] Current Status: IN-PROGRESS API Calls Requested: [Inventory API / Trading API] I have tried updating the support ticket associated with the application, but have not received any response. Has anyone else recently faced significant delays with their Compatible Application Check? What is the current average turnaround time for limit increases? Is there a better way to escalate this or get in touch with the developer support team directly (other than standard support tickets)? Any advice or insights from fellow developers or eBay staff on this forum would be greatly appreciated.

After going through the registration flow, I'm redirected back to the register page with a message saying I don't have an account. The loop repeats no matter how many times I try.

Thanks yesterday at 7:44 PMjustgubbinsEstablished eBay seller seeking manual review of Developer Program registration Hello eBay Developer Team, I am requesting a manual review of my Developer Program registration. I have been an active eBay seller since 2023 and have built an established account with over 100 positive feedback ratings and excellent seller performance. I operate my eBay business under the name Just Gubbins . I am developing a private internal application that will use the official eBay APIs to: Research active and sold listings to make informed purchasing decisions. Calculate profitability and return on investment (ROI). Manage my inventory. Assist with creating and managing my own eBay listings. Improve the efficiency of my day-to-day eBay selling operations. This application is solely for managing my own eBay business. I do not intend to redistribute eBay data, provide data to third parties, or use the APIs in any way that violates the eBay API License Agreement. My Developer Program registration was rejected, but I was not provided with a reason. I would greatly appreciate a manual review of my application. If there is any information that needs to be corrected or additional verification is required, I would be happy to provide it. I am genuinely trying to build a legitimate tool for my own eBay business using the official APIs, and I would appreciate any guidance on how I can complete the registration successfully. Thank you for your time and consideration. 2 days agosonomaresaleNegotiation API Call For Previously Sent Offers? When offers are sent out via the Negotiation API the response on a successfully completed call looks like this: username offer: {'offers': [{'offerId': '#1#####', 'revision': '#2#####', 'buyer': {'maskedUsername': '********'}, 'creationDate': 'datetime string', 'lastModifiedDate': 'datetime string', 'offerDuration': {'value': 4, 'unit': 'DAY'}, 'offerStatus': 'PENDING', 'initiatedBy': 'username', 'offeredItems': [{'listingId': '#3#####', 'quantity': 1, 'discountPercentage': 'float'}], 'allowCounterOffer': False, 'offerType': 'SELLER_INITIATED_OFFER'}]} And when you go into the seller hub, find a specific listing you can view expired/pending/completed offers by going to the item and checking the dropdown "review all offers" and find a link looking like this: https://www.ebay.com/sio/offers/reviewOffer/#####?threadId=####&offerId=#### If you take some of the information from the response, you can get a URL that shows the specific offer that was sent out via the call, like this: https://www.ebay.com/sio/offers/reviewOffer/#3#####?threadId=#2#####&offerId=#1##### Is there an existing API call to find previously sent offers, even if it's one where you have to know the identifying information beforehand? My reason for wanting this information was to use historical data to better decide the price of offers being sent out. 2 days agoandersonassetgroupHelp With APIs for my Listing/ERP Application Hello, I've written an application that uses eBay's APIs to list/manage my stores inventory. My application connects and has all of the correct API/Auth rights setup. I'm using an AI to code the project and it set it up to where the listing is created in drafts, but not in the Listings Drafts, instead it is putting them in "Inventory > Offers". For the life of me, I cannot seem to find this menu option anywhere on eBay. I don't even see a menu option for "Inventory" Does anyone know where that menu location is?

Question: Where can I find that library? 3 days agoredticketApproved method for accessing sold/completed listing data for sell-through research? I am developing a reseller research application. We currently use the eBay Browse API successfully for active listing data. Before continuing development, I want to confirm the approved method for product-level sell-through research. The proposed feature would compare sold/completed listings for a specific product or search term with current active listings over a defined period. Is there an approved eBay API, restricted API, licensed data source, or other authorized method to access sold/completed listing data for this use case? We do not want to scrape eBay or use eBay marketplace data in a prohibited manner. We are specifically seeking the correct authorized path and confirmation that this type of product-level sell-through research is permitted. Thank you. 3 days agomotzifr_85Client credentials OAuth token request returns 401 after resolving "Non Compliant" keyset status — personal read-only Browse API tool Hi eBay Developer Support team, I'm building a personal-use, read-only tool that only calls the Browse API's item_summary/search to monitor public listings (electronics categories) for my own private price-watching. No OAuth user sign-in, no listing/order management, no eBay member personal data is requested, stored, or displayed to anyone else. My Production keyset was initially shown as "Non Compliant" / "Your Keyset is currently disabled" due to the Marketplace Account Deletion notification requirement. I applied for and was granted the exemption ("I do not persist eBay data"), and the Application Keys page now shows the keyset as active (no disabled banner, App ID/Cert ID visible, no errors on that page). However, requesting an application access token via the client_credentials grant (POST to the identity/v1/oauth2/token endpoint, Basic Auth with my App ID/Cert ID, scope=https://api.ebay.com/oauth/api_scope) still consistently returns 401 Unauthorized, hours after the exemption was approved. I've seen several other recent posts here about accounts/keysets being flagged by a separate "internal eligibility and risk controls" review for very similar personal, read-only use cases. Could someone confirm whether that applies here too, or whether there's simply a longer propagation delay expected? Happy to provide any further details needed. Thank you! 3 days agosoldierofhopeDeveloper account registration and appeal auto-rejected — requesting manual review I'm an established eBay buyer/seller of nearly 20 years requesting API access to manage my own listings. I'm not building a 3rd app and will not access other users' data. I'm a US-based seller and am a local small business owner trying to scale via the platform he loves. I'll need the following APIs for these use-cases: - Sell Inventory API — to programmatically create eBay listings (createOrReplaceInventoryItem, createOffer, publishOffer) directly from my own seller account. This is for my own private internal inventory automation tool, not a third-party application. No other users' data is involved. - Sell Fulfillment API — to monitor order status so sold items can be automatically delisted from other platforms to prevent double-selling. - Sell Account API — to reference my existing business policies (payment, fulfillment, return) required by the Inventory API when publishing offers. - Taxonomy API — to programmatically identify the correct eBay cat ID for each item being listed. My username is soliderofhope, I am a US-based seller, my tool is private and internal-use only, and all listings are created and authenticated via my own account via OAuth. @ developer-support@ebay.com @ ebay.com Since this appears to be an automated risk-control flag rather than a reviewed decision, could someone from the team take a manual look and let me know what specifically triggered the rejection? Happy to provide any additional information needed. I have sent numerous emails to dev-relations@ebay.com to no response. Please advise.

Could someone help me confirm: 1. Whether this application/keyset has been approved for Sell API (sell.fulfillment) access in Production, or if further approval is required. 2. Whether there is a mismatch between the RuName used for consent and this App ID/Cert ID pair. Thank you for your help. 1 week agolast reply 5 days agory108098Developer account declined on risk/eligibility review — likely account-linkage timing issue (rneldner) Hello eBay Developer Support team, I submitted the "My account registration was rejected" form and received a reply letting me know that, following review, my developer account activation was declined against eBay's internal eligibility and risk controls, with an invitation to reapply later. I understand you can't share the specific evaluation details, but I think I may know the cause and would appreciate your guidance. Developer username: rneldner Registration email: rneldner@gmail.com Here's the likely issue: at the time I submitted my developer application, I did not yet have an active eBay member account. I previously had an eBay account that was terminated after a long period of non-use, and I only re-registered my eBay member account after submitting the developer application. So when the review ran, there was probably no active, verified member account to evaluate me against. My eBay member account is now active again, with a confirmed email and phone. Given that, could you advise on the best path forward — for example, whether I should reapply now that the account is active and linked, whether there's a waiting period you'd recommend, or anything specific I can do to satisfy the eligibility requirements? For context, the intended use is very low-risk: a single-user, personal tool for my own use as an eBay buyer in the US. It only uses the Browse API to search listings for specific Magic: The Gathering cards I'm trying to buy to complete my collection. Usage is read-only and on my own behalf — I don't store, redistribute, or display eBay data to anyone else — and the purpose is to help me find and purchase cards on eBay.
