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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.HttpRequest')
loReq = CreateObject('Chilkat.HttpRequest')

loReq.Path = "/token"

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')

loResp.GetBodySb(loSbResponseBody)
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')

* Sample JSON response:

* {

*   "userName": "your_username",

* ----------------------------------
* Use the OAuth2 token in a request.
* For example...

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbXml = CreateObject('Chilkat.StringBuilder')
lnSuccess = loSbXml.LoadFile("c:/someDir/someXmlFile.xml","utf-8")
IF (lnSuccess = 0) THEN
    ? "Failed to load the XML file."
    RELEASE loHttp
    RELEASE loReq
    RELEASE loSbResponseBody
    RELEASE loJResp
    RELEASE loSbXml
    CANCEL
ENDIF

* Get the OAuth2 token and use it for authentication
loHttp.AuthToken = loJResp.StringOf("token")

lcDestUrl = "https://your_api.azurewebsites.net/destinationUrl"

    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loReq
    RELEASE loSbResponseBody
    RELEASE loJResp
    RELEASE loSbXml
    CANCEL
ENDIF

lnRespStatusCode = loResp.StatusCode

IF (lnRespStatusCode >= 400) THEN
    ? "Response Header:"

    RELEASE loResp
    RELEASE loHttp
    RELEASE loReq
    RELEASE loSbResponseBody
    RELEASE loJResp
    RELEASE loSbXml
