(Chilkat2-Python) GeoOp Exchange Refresh Token for New Access Token

Demonstrates how to use the /oauth2/token endpoint to exchange it for a new access token once the current access token has expired.

Note: This example requires Chilkat v9.5.0.65 or greater.

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

# This example also assumes that OAuth2 access and refresh tokens were previously fetched.
# and saved in a JSON file.  

# First get our previously obtained refresh token.
# { .... "refresh_token":"e6dqdG....mzjpT04w==", .... }
