Referencing local variables in an http post call

[mseigal]

Hello,

My company is about to go live with Zoom. We are on track for day 1 contact center flows.

We would like to implement an authentication layer to verify callers against D365 contact values before they get routed to a human agent who will get a case pop.
We have a D365 dev who has published apis and they work fine. I have used these apis in the past with other tools that make use of the api schema such as n8n webhooks and postman. I have noticed that the call using json body parameters works as expected, only if I reference the collect input widget directly. (eg. Collect_SiteID.digits). If I try and reference a set variable path, the value is not passed the http call.

This is not an issue at the moment as we will only go live with the non human authentication layer in Jan 2026 at the earliest and I can get it to work. Zoom's documentation seems to suggest you can pass in variables. Why else would they be there? Is there any end to end resource that rinses this process. For example, there are thousands of videos aimed at intermediate users figuring out workflows in n8n, shell scripting, Siri shortcuts and Obsidian automation. Our company is a key player in the UK edtech market and we offer that depth of onboarding for new customers trying to master our SAAS platform. it would be greatly appreciated if some of Zoom's power features in terms of automation were documented this way.
