Refresh eBay Application Access Token

See more eBay Examples

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

// 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"
// }

let json = chilkat::JsonObject::new();
if json.load_file("qa_data/tokens/ebay-access-token.json").is_err() {
    println!("Failed to load the existing ebay access token JSON.");
    return;
}

let oauth2 = chilkat::OAuth2::new();

oauth2.set_token_endpoint("https://api.sandbox.ebay.com/identity/v1/oauth2/token");

// Replace these with actual values.
oauth2.set_client_id("EBAY_CLIENT_ID");
oauth2.set_client_secret("EBAY_CLIENT_SECRET");

// Get the "refresh_token"
oauth2.set_refresh_token(&json.string_of("refresh_token").unwrap_or_default());

// Send the HTTP POST to refresh the access token..
if oauth2.refresh_access_token().is_err() {
    println!("{}", oauth2.last_error_text());
    return;
}

// Load the access token response into the JSON object 
let _ = json.load(&oauth2.access_token_response());

// 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.set_emit_compact(false);
let _ = json.write_file("qa_data/tokens/ebay-access-token.json");

println!("OAuth2 authorization granted!");
println!("New Access Token = {}", oauth2.access_token());
