How to Create a Developer Account on eBay and Generate an Authorization Token

Integrating your application with eBay APIs requires creating a developer account on eBay's developer portal and obtaining an authorization token. This guide will walk you through the process step by step, helping you set up everything you need to interact with eBay’s vast e-commerce ecosystem.

Step 1: Sign Up for an eBay Developer Account

1. Visit the eBay Developer Program Website: Go to eBay's developer portal.
2. Sign Up for a Developer Account: Click on the Sign in button at the top right of the page. If you already have an eBay account, you can log in using those credentials. Otherwise, click on Create a Developer Account. You will need to fill in your account details, including your email address, password, and other required information like your company name (if applicable). Once you have completed the form, agree to the eBay Developer Program terms and click on Register.
3. Verify Your Email Address: After registering, eBay will send you an email to verify your account. Follow the link in the email to confirm your account.

Step 2: Create an eBay Application

Once your account is created and verified, you will need to create an application within the eBay Developer portal to interact with the eBay APIs.

1. Navigate to the Dashboard: After logging in, click on the Dashboard tab at the top of the developer portal.
2. Create an application: Under My Apps, click on Create a New Application. You will be asked to provide details for your application such as the App Name, environment (sandbox or production), and API scopes. Start by selecting the Sandbox environment to test your integration in eBay's testing environment.
3. Generate App Keys: Once the application is created, eBay will generate API credentials (App ID, Cert ID, and Dev ID) for both the sandbox and production environments. These credentials will allow your application to authenticate and interact with eBay APIs.

Step 3: Generate OAuth Authorization Tokens

To make authenticated requests to eBay's APIs, you will need an OAuth 2.0 token. Follow these steps to generate an authorization token:

1- Identify the URL

o??? Sandbox: https://auth.sandbox.ebay.com/oauth2/authorize

o??? Production: https://auth.ebay.com/oauth2/authorize

2- Identify the scope of access:

For example:

o??? https://api.ebay.com/oauth/api_scope

o??? https://api.ebay.com/oauth/api_scope/sell.fulfillment

o??? https://api.ebay.com/oauth/api_scope/sell.inventory

o??? https://api.ebay.com/oauth/api_scope/sell.finances

3- Create URL:

Part 1 - https://auth.sandbox.ebay.com/oauth2/authorize Part 2 – Get client id from keyset

?client_id=wasifali-wasif-SBX-ce57bb893-67df5ec1

Part 3 - response_type=code

Part 4 – Get RUNAME from highlighted part

redirect_uri=wasif_ali-wasifali-wasif—gxgyckdt

Part 5 – Create scope list with plus (+) delimiter as per your need scope=https://api.ebay.com/oauth/api_scope+https://api.ebay.com/oauth/api_scope/sell.fulfillment+https://api.ebay.com/oauth/api_scope/sell.inventory+https://api.ebay.com/oauth/api_scope/sell.finances

Part 6 - state=State

Part 7- Final URL

https://auth.sandbox.ebay.com/oauth2/authorize?client_id=wasifali-wasif-SBX-ce57bb893-67df5ec1&response_type=code&redirect_uri=wasif_ali-wasifali-wasif--gxgyckdt&scope=https://api.ebay.com/oauth/api_scope+https://api.ebay.com/oauth/api_scope/sell.fulfillment+https://api.ebay.com/oauth/api_scope/sell.inventory+https://api.ebay.com/oauth/api_scope/sell.finances&state=State

4.????? Get the user consent

o??? Run the final URL on browser and add the credentials and after successfully logged in copy the URL

5.????? Code extraction from URL

6.????? Create Basic Authentication for header

o??? Copy the client id and client secret and encode to base 64 for basic authentication

Example ??Client id : client secret

7.?Create Postman request for access token

o??? Header

o??? Body

Curl Request

curl?--location?--request?POST?'https://api.sandbox.ebay.com/identity/v1/oauth2/token'?\

--header?'Content-Type:?application/x-www-form-urlencoded'?\

--header?'Authorization:?Basic?d2FzaWZhbGktd2FzaWYtU0JYLWNlNTdiYjg5My02N2RmNWVjMTpTQlgtZTU3YmI4OTM0YWVlLTdkZDMtNDBiNy1iNzZkLWM5N2I='?\

--header?'Cookie:?dp1=bu1p/QEBfX0BAX19AQA**6aa2c730^;?ebay=%5Esbf%3D%23%5E'?\

--data-urlencode?'code=v^1.1#i^1#f^0#r^1#I^3#p^3#t^Ul41XzQ6NUI4NjBFNTVEQjU5NEExQzM2RDdFNEUzRjRFNzE5MDVfMl8xI0VeMTI4NA=='?\

--data-urlencode?'grant_type=authorization_code'?\

--data-urlencode?'redirect_uri=wasif_ali-wasifali-wasif--gxgyckdt'

o??? Response

8.??Refresh Token

o??? Duplicate the request of a postman

o??? Copy the refresh token which was generated in response of the previous request

o??? Change grant_type=refresh_token

o??? Add refresh_token on body and paste the refresh token
