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

# Sends the following PUT request:
# PUT https://marketplace.walmartapis.com/v2/inventory?sku={SKU}

sbUrl = chilkat2.StringBuilder()

# First we need to generate a signature for our request.
# The signature needs to be re-generated for each new Walmart HTTP request.

# header fields: WM_SEC.AUTH_SIGNATURE, WM_SEC.TIMESTAMP, and WM_QOS.CORRELATION_ID

# Note: Do not explicitly set the "Host" header.  Chilkat will set it automatically.

# The body of the PUT request will be XML that looks like this:

# 	    </wm:quantity>
# 	    <wm:fulfillmentLagTime>5</wm:fulfillmentLagTime>
# 	</wm:inventory>

# Build the XML request body:
originalAmount = 234
