func chilkatTest() {
    // Note: Requires Chilkat v9.5.0.65 or greater.

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

    // Load our previously obtained access token. (see PayPal OAuth2 Access Token)
    let jsonToken = CkoJsonObject()!
    jsonToken.loadFile("qa_data/tokens/paypal.json")

    // Build the Authorization request header field value.

    sbAuth.append(jsonToken.string(of: "token_type"))
    sbAuth.append(" ")
    sbAuth.append(jsonToken.string(of: "access_token"))

    // Make the initial connection.
    // A single REST object, once connected, can be used for many PayPal REST API calls.
    // The auto-reconnect indicates that if the already-established HTTPS connection is closed,
    // then it will be automatically re-established as needed.
    let rest = CkoRest()!

        return
    }

    // ----------------------------------------------------------------------------------------------
    // The code above this comment could be placed inside a function/subroutine within the application
    // because the connection does not need to be made for every request.  Once the connection is made
    // the app may send many requests..
    // ----------------------------------------------------------------------------------------------

    // Build the JSON request body containing the reminder information:
    let json = CkoJsonObject()!
    json.emitCompact = false
    json.update("subject", value: "Past due")
    json.update("note", value: "Please pay soon")
    json.updateBool("send_to_merchant", value: true)
    print("\(json.emit()!)")

    // The JSON created by the above code:

    // 	{ 
    // 	  "subject": "Past due",
    // 	  "note": "Please pay soon",
    // 	  "send_to_merchant": true,
    // 	}

    // Build a path using a previously-sent invoice ID.
    let sbPath = CkoStringBuilder()!
    sbPath.append("/v1/invoicing/invoices/invoice_id/remind")
    var numReplacements: Int = sbPath.replace("invoice_id", replacement: "INV2-ZG2H-HKAW-PMWU-N6ZR").intValue

    json.emitCompact = true

    let sbResponseBody = CkoStringBuilder()!

    rest.addHeader("Content-Type", value: "application/json")
    rest.addHeader("Authorization", value: sbAuth.getAsString())
    json.emitSb(sbRequestBody)

    success = rest.fullRequestSb("POST", uriPath: sbPath.getAsString(), requestBody: sbRequestBody, responseBody: sbResponseBody)
    if success != true {
        print("\(rest.lastErrorText!)")
        return
    }

    print("Response Status Code = \(rest.responseStatusCode.intValue)")

    // Did we get a 202 accepted response?
    if rest.responseStatusCode.intValue != 202 {
        print("\(sbResponseBody.getAsString()!)")
        print("Failed.")
        return
    }

    // If the 202 response is received, the response body would be empty...
    print("Success.")
