Access and Security

Create an account here https://developer.ebay.com/my/keys and generate keys for production.

For example:

Navigate to user tokens https://developer.ebay.com/my/auth/?env=production&index=0 and select following options.

From the same page, generate the ebay redirect URL (called RU)

Copy the URL of the field "Your branded eBay Production Sign In (OAuth)" and open in a new browser in private mode and also save a copy of the URL for future use. Log in with your store user ID and password and you will be redirected to the following page

Copy the URL of the thank you page and assign it to a variable called "secureURL" and execute the following function.

public async Task<string> GetRefreshToken()
{
    string secureURL="replace with the URL of the thank you page";
    EbaySharp.Controllers.IdentityController identityController = new EbaySharp.Controllers.IdentityController();
    string refreshToken = await IdentityController.GetRefreshToken(ReplaceYourClientId, ReplaceYourClientSecret, 
        , secureURL, Replace with RU);
}

This method returns a refresh token which is valid for 18 months or If you change your user/id or password. You will need to re run this function after 18 months when refresh token has expired. We will use the refresh token and generate an access token.

IdentityController identityController=new IdentityController();
var clientCredentials = await identityController.GetClientCredentials(ReplaceYourClientId, ReplaceYourClientSecret, ReplaceWithRefreshToken , ReplaceWithScopes);

Provide scope separated by a space, for example https://api.ebay.com/oauth/api_scope https://api.ebay.com/oauth/api_scope/sell.marketing.readonly This method now gives you ClientCredentialsResponse object which contains an access token.

Using the EbaySharp

Initialize the instance with the access token.
