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

* Use a previously obtained user token.  The token should look something like this:
* "v^1.1#i^1#r^0#p^3#I^3#f^0#t^H4sIAAAAAAAAAOVXa2wUVRTu9k ... 89xuCWYREAAA=="
lcAccessToken = "EBAY_ACCESS_TOKEN"

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* This example uses the sandbox.  
* Change "api.sandbox.ebay.com" to "api.ebay.com" to use the production system.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbUrl = CreateObject('Chilkat.StringBuilder')
loSbUrl.Append("https://api.sandbox.ebay.com/sell/inventory/v1/inventory_item?limit=_LIMIT&offset=_OFFSET")
lnNumReplaced = loSbUrl.Replace("_LIMIT","100")
* The offset indicates the page number.  Offset 0 gets items 0-99 (if limit=100),
* Offset 1 gets items 100-199, etc.
lnNumReplaced = loSbUrl.Replace("_OFFSET","0")

* Add our access token to the request, which is a header
* having the following format:
* Authorization: Bearer <userAccessToken>
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbAuth = CreateObject('Chilkat.StringBuilder')
loSbAuth.Append("Bearer ")
loSbAuth.Append(lcAccessToken)

* The response should be JSON, even if an error.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
