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

    // Use your API key and secret here...
    apiKey := "o9rw6Gq0RnqlkfaSqtCMOA"
    apiSecret := "UslmE23Kjh7at9z3If1xAHEyLmPDNxvxQrjR"

    // Create a JWT to authenticate Zoom API requests.
    jwt := chilkat.NewJwt()

    jose := chilkat.NewJsonObject()
    success := jose.UpdateString("alg","HS256")
    success = jose.UpdateString("typ","JWT")

    // Build claims to look like this:
    // {"aud":null,"iss":"o9rw6Gq0RnqlkfaSqtCMOA","exp":1627651762,"iat":1627646363}
    claims := chilkat.NewJsonObject()
    success = claims.UpdateString("iss",apiKey)
    success = claims.UpdateNull("aud")

    // Set the timestamp of when the JWT was created to now.
    curDateTime := jwt.GenNumericDate(0)
    success = claims.AddIntAt(-1,"iat",curDateTime)

    // Set the timestamp defining an expiration time (end time) for the token
    // to be now + 1 month(3600 * 24 * 30 seconds)
    oneMonth := 3600 * 24 * 30
    success = claims.AddIntAt(-1,"exp",curDateTime + oneMonth)

    // Produce the smallest possible JWT:
    jwt.SetAutoCompact(true)

    strJwt := jwt.CreateJwt(*jose.Emit(),*claims.Emit(),apiSecret)

    fmt.Println(*strJwt)

    // Let's test the JWT to by sending the following request:

    // curl --request GET \
    //   --url 'https://api.zoom.us/v2/users?status=active&page_size=30&page_number=1' \
    //   --header 'authorization: Bearer { your_token }' \

    // Implements the following CURL command:

    // curl --request GET \

    //   --header 'authorization: Bearer { your_token }' \

    // Use the following online tool to generate HTTP code from a CURL command
