When working with Zapier, adding data to arrays needs some extra JavaScript to convert the data. Zapier calls arrays "Line Items" and formats them like so, [123,456,789]
whereas Siteglide API expects a JavaScript formatted array such as, ["123","456","789"]
To convert these two data types, use the screenshots and code below. In this example we are getting a pre-existing user and their Secure Zones, then adding in a new item.
The above javascript code and flow can be used for anywhere that you need to add an item to Line Items within Zapier
