Update a Google Contact

See more Google APIs Examples

Demonstrates how to update a Google Contact. Rust

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

// --------------------------------------------------------------------------------------------------------
// Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.
// Once connected, the REST object may be re-used for many REST API calls.
// (It's a good idea to put the connection setup code in a separate function/subroutine.)
// --------------------------------------------------------------------------------------------------------

// It is assumed we previously obtained an OAuth2 access token.
// This example loads the JSON access token file 
// saved by this example: Get Google Contacts OAuth2 Access Token

let json_token = chilkat::JsonObject::new();

// ----------------------------------------------
// OK, the REST connection setup is completed..

// To update a contact, we'll first get the contact information,
// then we'll make changes to the XML and then PUT the update.
