* This example assumes 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.Http')
loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl -X POST \
*   https://api.cc.email/v3/activities/add_list_memberships \
*   -H 'Accept: application/json' \
*   -H 'Authorization: Bearer {access_token}' \
*   -H 'cache-control: no-cache' \
*   -H 'content-type: application/json' \
*   -d '{
*   "source": {
*     "contact_ids": [
*       "{contact_id1}",
*       "{contact_id2}",
*       "{contact_id3}",
*       "{contact_id4}",
*       "{contact_id5}",
*       "{contact_id6}"
*     ]
*   },
*   "list_ids": [
*     "{list_id1}",
*     "{list_id2}"
*   ]
* }'

* Generate Code to Create JSON

* The following JSON is sent in the request body.

* {

*     "contact_ids": [
*       "{contact_id1}",
*       "{contact_id2}",

*   "list_ids": [
*     "{list_id1}",
*     "{list_id2}"
