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. Swift

func chilkatTest() {
    var success: Bool = 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"
    // }

    let json = CkoJsonObject()!
    success = json.loadFile(path: "qa_data/tokens/ebay-access-token.json")
    if success == false {
        print("Failed to load the existing ebay access token JSON.")
        return
    }

    let oauth2 = CkoOAuth2()!

    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.string(of: "refresh_token")

    // Send the HTTP POST to refresh the access token..
    success = oauth2.refreshAccessToken()
    if success == false {
        print("\(oauth2.lastErrorText!)")
        return
    }

    // Load the access token response into the JSON object 
    json.load(json: 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(path: "qa_data/tokens/ebay-access-token.json")

    print("OAuth2 authorization granted!")
    print("New Access Token = \(oauth2.accessToken!)")
