Send JSON REST Request, Get JSON Response

See more REST Examples

Demonstrates sending a RESTful JSON request, and receiving a JSON response. This example will create a bucket in Google Cloud Storage (which involves sending and receiving JSON). Xojo Plugin

Dim success As Boolean
success = False

// This example will create a bucket in Google Cloud Storage.

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

Dim gAuth As New Chilkat.AuthGoogle
// Obtain an access token as shown in one of the following examples:
// See Get Access Token using a Service Account JSON Key
// See Get Access Token using a P12 File

// Provide the authentication credentials (i.e. the access key)

// Build the JSON request body for creating a bucket.
// The only required property is the "name", but we'll add more
// to make a better example..
