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

# See Get Wish OAuth2 Access Token 
# for sample code showing how to obtain a Wish access token for desktop apps.

# This example assumes we previously obtained an OAuth2 access token for Wish.

# Note: In most OAuth2 implementations, the token endpoint is the same for both the
# refresh request and the exchange-code-for-token request (which happens when getting
# the OAuth2 token for the 1st time).   Wish uses a different URL for the refresh:
oauth2.TokenEndpoint = "https://merchant.wish.com/api/v3/oauth/refresh_token"

# The following uncommon option was added in Chilkat v9.5.0.85
oauth2.UncommonOptions = "EXCHANGE_CODE_FOR_TOKEN_USING_GET"

# Replace these with actual values.
oauth2.ClientId = "WISH-CLIENT-ID"
oauth2.ClientSecret = "WISH-CLIENT-SECRET"

# Get the "refresh_token"
oauth2.RefreshToken = jsonToken.StringOf("data.refresh_token")

# Send the HTTP request to refresh the access token..
success = oauth2.RefreshAccessToken()
if (success != True):
    print(oauth2.LastErrorText)
    sys.exit()

# 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.
