API endpoint parameters

I'm trying to use the WFM public API to access some of our team's custom report templates. I was told over the Support channel that I should hit the API endpoint using a url similar to this:

/v1/reports/{templateId}/data

However, I'm unsure what is supposed to be used in place of the {templateId} placeholder. I tried using the name of the custom report (in this case “Tier 1”) but the API did not recognize that object and threw an error:

Requesting: https://[REDACTED].zendesk.com/wfm/public/api/v1/reports/Tier 1/data?startTime=1762837201&endTime=1762837201 Error 422 - {"message":{"templateId":["Invalid uuid","Template with this ID does not exists"]},"success":false}

I tried using “Tier 1” as well as “Tier%201” in case the space was the problem, but got the same error. It seems like we need to use the uuid for the custom report template. There is no documentation online about how to directly reference a custom report template or find the uuid for a report template. How do I get this uuid to get this API string working properly?
