eBay Buy API

Promoting eBay inventory and initiating eBay Guest Checkout on your site.

EPN requires written approval for this promotional method.


We are excited that you are considering integrating with the eBay Buy APIs!  The eBay Buy APIs let you create eBay buying experiences outside of eBay sites. The Buy APIs allow users to search for, select, and buy eBay items, all without leaving your own site. The eBay Buy APIs are available in sandbox today for anyone who has an eBay Developer’s account. Only those requesting access to eBay Guest Checkout API will be required to fill out the application for production access below.


The requirements to integrate with eBay’s Buy APIs can be found here:   https://developer.ebay.com/api-docs/buy/static/buy-requirements.html


Please note that the eBay checkout APIs are only designed for US sellers to US buyers at this time.


After reading these requirements, if you are ready to proceed with enabling eBay Guest Checkout on your site, please complete and submit the form below. All fields are required. If a question is not applicable to you, please reply "N/A" to that question.

Once you submit this application, you will receive an automated email response from eBay Partner Network’s Customer Support Team. Please respond directly to that email and attach the following:


  • Certificate of Attestation for PCI Compliance. Alternatively, we have partnered with Braintree to vault credit card information. If you would like to utilize Braintree, you will still be required to be PCI Compliant. https://articles.braintreepayments.com/reference/security/pci-compliance
  • Mock-ups of the user experience with screenshots at each stage in the checkout flow. Please call out which API calls you are using at each stage.
  • Data flow diagram of every API call you plan to implement into your application. Please explain what API capabilities are being called, the entities that are calling each API and the sequence in which they are being called.


After we receive your completed application, we will review it and respond within 10 business days.



You will be required to gain additional approval from the Developers Network Team in order to productionalize this API call. Meeting the  standard eligibility  is not a guarantee that production access will be granted.
