First, verify that you are using the correct type of token:
- REST API calls that only do searches (e.g., the Browse API) can use an Application access token.
- REST API calls that get a user’s personal data must use a User access token.
User tokens typically expire within two hours. Therefore, if you’re using a tool like the eBay API Explorer, Postman, or SOAPui to test your requests and you’re pasting in a user token, please keep in mind that you’ll need to get a new user token every 2 hours or so.
To update a user token without signing into eBay every time, configure a refresh token, and then use it to get new user access tokens programmatically.
