(SQL Server) Get OAuth 2.0 Access Token using G_SvcOauthAccessToken2

Obtains an OAUTH2 access token from the Google OAuth 2.0 Authorization Server using the G_SvcOauthAccessToken2 method. This is for Server to server applications using Google API's that need an access token. See https://developers.google.com/accounts/docs/OAuth2ServiceAccount

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

// Important: See this note about string length limitations for strings returned by sp_OAMethod calls.

    -- See Global Unlock Sample for sample code.

    DECLARE @http int
    EXEC @hr = sp_OACreate 'Chilkat_9_5_0.Http', @http OUT
    IF @hr <> 0

    -- When a service account (Client ID) is created at https://code.google.com/apis/console/
    -- Google will generate a P12 key.  This is a PKCS12 (PFX) file that you will download
    -- and save.  The password to access the contents of this file is "notasecret".
    -- NOTE: The Chilkat Pfx API provides the ability to load a PFX/P12 and re-save
    -- with a different password.

    -- Begin by loading the downloaded .p12 into a Chilkat certificate object:

    -- desired duration with a max of 3600 seconds (1 hour).

    -- (see https://developers.google.com/accounts/docs/OAuth2ServiceAccount
    -- iss: The email address of the service account.
    -- scope: A space-delimited list of the permissions that the application requests.
    -- sub: The email address of the user for which the application is requesting delegated access.
    -- numSec: The number of seconds for which the access token will be valid (max 3600).

    -- The "sub" param is required if there is an email address, such as for a

    -- can authorize an application to access user data on behalf of users in the Google Apps domain.
    --
