Azure OAuth2 Client Credentials Grant Flow

See more OAuth2 Examples

Demonstrates how to get an OAuth2 access token for an Azure Registered App using the Client Credentials Grant Flow.

Note: Your Azure app must be registered as a single-tenant app to use client credentials.

Go

    success := false

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

    http := chilkat.NewHttp()

    req := chilkat.NewHttpRequest()
    req.AddParam("client_secret","CLIENT_SECRET")
    req.AddParam("client_id","CLIENT_ID")

    // See Understanding Scopes in Azure OAuth2 Client Credentials Flow
    req.AddParam("scope","https://graph.microsoft.com/.default")

    req.AddParam("grant_type","client_credentials")

    // Note: Your Azure app must be registered as a single-tenant app to use client credentials.
    // Use your own tenant ID, for example 4d8fdd66-66d1-43b0-ae5c-e31b4b7de5cd
    url := "https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token"

    req.SetHttpVerb("POST")
    req.SetContentType("application/x-www-form-urlencoded")

    resp := chilkat.NewHttpResponse()
    success = http.HttpReq(url,req,resp)
    if success == false {
        fmt.Println(http.LastErrorText())
        http.DisposeHttp()
        req.DisposeHttpRequest()
        resp.DisposeHttpResponse()
        return
    }

    statusCode := resp.StatusCode()
    fmt.Println("Response status code = ", statusCode)

    json := chilkat.NewJsonObject()
    json.Load(resp.BodyStr())

    json.SetEmitCompact(false)
    fmt.Println(*json.Emit())

    // Sample successful output:

    // {
    //   "token_type": "Bearer",
    //   "expires_in": 3599,
    //   "ext_expires_in": 3599,
    //   "access_token": "eyJ0eX...K0jOERg"
    // }

    if statusCode == 200 {
        json.WriteFile("qa_data/tokens/azureClientCredentialsToken.json")
        fmt.Println("Success.")
    } else {
        fmt.Println("Failed.")
    }
