* Note: Requires Chilkat v9.5.0.64 or greater.

* This 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.Rest')
loRest = CreateObject('Chilkat.Rest')

* Before sending REST API calls, the REST object needs to be
* initialized for OAuth1.
* See Xero 2-Legged OAuth1 Setup for sample code.

* Assuming the REST object's OAuth1 authenticator is setup, and the initial
* connection was made, we may now send REST HTTP requests..

* --------------------------------------------------------------
* This example will upload an image attachment to a receipt.

lcEndPoint = "Receipts"
lcReceiptID = "c4f40e59-c390-0001-caff-ce731c707d00"
* This JPG image can be downloaded from https://www.chilkatsoft.com/syncedImages/penguins.jpg
lcFilename = "penguins.jpg"

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbPath = CreateObject('Chilkat.StringBuilder')
loSbPath.Append("/api.xro/2.0/{Endpoint}/{Guid}/Attachments/{Filename}")
lnNumReplaced = loSbPath.Replace("{Endpoint}",lcEndPoint)
lnNumReplaced = loSbPath.Replace("{Guid}",lcReceiptID)
lnNumReplaced = loSbPath.Replace("{Filename}",lcFilename)

loRest.AddHeader("Content-Type","image/jpeg")

* Load the JPG image from a file.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loJpgData = CreateObject('Chilkat.BinData')
lnSuccess = loJpgData.LoadFile("qa_data/jpg/penguins.jpg")

* We could alternatively get it from a URL like this:
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loJpgDataFromWeb = CreateObject('Chilkat.BinData')
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')
lnSuccess = loHttp.QuickGetBd("https://www.chilkatsoft.com/syncedImages/penguins.jpg",loJpgDataFromWeb)
IF (lnSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loRest
    RELEASE loSbPath
    RELEASE loJpgData
    RELEASE loJpgDataFromWeb
    RELEASE loHttp
    CANCEL
ENDIF

* Upload with a POST
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbResponseBody = CreateObject('Chilkat.StringBuilder')
lnSuccess = loRest.FullRequestBd("POST",loSbPath.GetAsString(),loJpgData,loSbResponseBody)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    RELEASE loSbPath
    RELEASE loJpgData
    RELEASE loJpgDataFromWeb
    RELEASE loHttp
    RELEASE loSbResponseBody
    CANCEL
ENDIF

* A 200 response is expected for actual success.
IF (loRest.ResponseStatusCode <> 200) THEN
    ? loSbResponseBody.GetAsString()
    RELEASE loRest
    RELEASE loSbPath
    RELEASE loJpgData
    RELEASE loJpgDataFromWeb
    RELEASE loHttp
    RELEASE loSbResponseBody
    CANCEL
ENDIF

* Examine the XML response
? loSbResponseBody.GetAsString()

* A successful response looks like this:
