(Swift) CardConnect Validate Merchant-Level Credentials

To test and validate merchant-level credentials, you can make a PUT request, including the merchant ID in the body of the request, to the base URL. The Gateway verifies that the MID matches the credentials provided in the header.

Note: This example requires Chilkat v11.0.0 or greater.

func chilkatTest() {
    var success: Bool = false

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

    let http = CkoHttp()!

    http.basicAuth = true
    http.login = "API_USERNAME"
    http.password = "API_PASSWORD"

    let json = CkoJsonObject()!
    success = json.update("merchid", value: "MERCHANT_ID")

    var url: String? = "https://<site>.cardconnect.com:<port>/cardconnect/rest/"

    let resp = CkoHttpResponse()!
    success = http.httpStr("PUT", url: url, bodyStr: json.emit(), charset: "utf-8", contentType: "application/json", response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    // If we get a 200 response status and an HTML response saying "CardConnect REST Servlet", then our credentials are correct.
    print("response status code = \(resp.statusCode.intValue)")

    print("response string:")
    print("\(resp.bodyStr!)")

    // Sample output:

    // response status code = 200
    // response string:
    // <html lang="en"><body><h1>CardConnect REST Servlet</h1></body></html
