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

loHttp = CreateObject('Chilkat.Http')

loHttp.BasicAuth = 1

* Build and send the following JSON:

* {
*   "merchid": "MERCHANT_ID",
*   "retref": "112989260941",
*   "signature": "BASE64_GZIPPED_BMP_DATA"
* }

loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("merchid","MERCHANT_ID")
loJson.UpdateString("retref","106631225001")

* Load the .bmp containing a 200px x 100px signature.
loBd = CreateObject('Chilkat.BinData')
lnSuccess = loBd.LoadFile("qa_data/bmp/signature.bmp")
* Gzip compress.
loGzip = CreateObject('Chilkat.Gzip')

* Add to the JSON in base64 format
loJson.UpdateString("signature",loBd.GetEncoded("base64"))
