Swift Requires Chilkat v11.0.0+

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.

Swift

func chilkatTest() {
    var success: Bool = false

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

    let http = CkoHttp()!

    let req = CkoHttpRequest()!
    req.addParam(name: "client_secret", value: "CLIENT_SECRET")
    req.addParam(name: "client_id", value: "CLIENT_ID")

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

    req.addParam(name: "grant_type", value: "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
    var url: String? = "https://login.microsoftonline.com/TENANT_ID/oauth2/v2.0/token"

    req.httpVerb = "POST"
    req.contentType = "application/x-www-form-urlencoded"

    let resp = CkoHttpResponse()!
    success = http.httpReq(url: url, request: req, response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    var statusCode: Int = resp.statusCode.intValue
    print("Response status code = \(statusCode)")

    let json = CkoJsonObject()!
    json.load(json: resp.bodyStr)

    json.emitCompact = false
    print("\(json.emit()!)")

    //  Sample successful output:

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

    if statusCode == 200 {
        json.writeFile(path: "qa_data/tokens/azureClientCredentialsToken.json")
        print("Success.")
    }
    else {
        print("Failed.")
