See more eBay Examples

This example shows how to get a new eBay REST API access token when the original is close to expiration. JavaScript

var success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The previously fetched eBay access token looks like this:

// {
//   "access_token": "v^1.1#i^1# ... HwSAAA=",
//   "expires_in": 7200,
//   "refresh_token": "v^1.1#i^1# ... FXjEyODQ=",
//   "refresh_token_expires_in": 47304000,
//   "token_type": "User Access Token"
// }

var json = new CkJsonObject();
success = json.LoadFile("qa_data/tokens/ebay-access-token.json");
if (success == false) {
    console.log("Failed to load the existing ebay access token JSON.");
    return;
}

var oauth2 = new CkOAuth2();

oauth2.TokenEndpoint = "https://api.sandbox.ebay.com/identity/v1/oauth2/token";

// Replace these with actual values.
oauth2.ClientId = "EBAY_CLIENT_ID";
oauth2.ClientSecret = "EBAY_CLIENT_SECRET";

// Get the "refresh_token"
oauth2.RefreshToken = json.StringOf("refresh_token");

// Send the HTTP POST to refresh the access token..
success = oauth2.RefreshAccessToken();
if (success == false) {
    console.log(oauth2.LastErrorText);
    return;
}

// Load the access token response into the JSON object 
json.Load(oauth2.AccessTokenResponse);

// Save the new JSON access token response to a file.
// The access + refresh tokens contained in this JSON will be needed for the next refresh.
json.EmitCompact = false;
json.WriteFile("qa_data/tokens/ebay-access-token.json");

console.log("OAuth2 authorization granted!");
console.log("New Access Token = " + oauth2.AccessToken);
