how can I fetch keyset (appID and certID) using sign-in credentials.

[ayugu-2205]

I am working on building an ebay market place integrator. I have my ebay sign-in credentials (username and password) and I want to fetch the keyset using sign-in credentials as response.

I have already created the keysets manually but now I want to fetch it automatically using API.

please suggest if anyone has any insight.

The keyset (appID+certID) is permanent, so once you create the keys, simply store them in a safe place on your server.

I need to fetch the keyset using username and password through API and want to make this process automated for all the credentials. I know how can I get the keyset manually but need help in API.

I'm not sure I understand the request. A developer needs only one static keyset. Are you trying to dynamically access the keysets of other developers? That would be unwise for other developers to expose their own keys in any manner.

Or are asking about the user token?  The first step is to present the user with a webpage where the user will log in and manually grant permission to access that user's account. This is done through a URL request as part of the Authorization Code Grant Flow.
