Zoho Creator / eBay: Get all Active Products

Zoho Creator / eBay: Get all Active Products

Category: Zoho
Hits: 20633
What?
This is an article to document a function used in Zoho Creator to retrieve the Product IDs of all the active products in a client's eBay store.

Why?
The use-case was that I wanted to retrieve a list of all the listed active products in a fixed price item listing. The example below is a function which, if given the page number and the number of entries per page, returns these in JSON as a Zoho Map datatype.

How?
I'm not going to go into detail on how I create an access token to query the eBay Trading API as you can read this in my article: Joellipman: Zoho Creator: Push to eBay Listings. You will note that I use the access token function (one that regenerates an access token or reuses if not expired). Thereafter, I use the GetMyeBaySelling API Call with specific criteria to only return the active listings as well as specific fields so my function doesn't get overwhelmed with the amount of data in the response:
copyraw 
map API.fn_eBayQuery_GetActiveProducts(int p_Page, int p_PerPage)
{
	/*
    Function: fn_eBayQuery_GetActiveProducts()
    Purpose: Fetches current listings / active products
    Date Created:   2021-10-13 (Joellipman.com - Joel Lipman)
                    - Initial release
