Why is the poll response synced as an alphanumeric ID value and not the actual responses?
You are seeing some poll responses as an alphanumeric ID value instead of the actual response in your Pendo schema.
You will need to open a support ticket with Pendo or reach out to your Pendo admin to understand what IDs match the correlating response value.
We use the endpoint,
https://app.pendo.io/api/v1/aggregation, to get pollEvent data. The Pendo API returns the value of poll response as a text or ID value. Fivetran will sync the data as passed from Pendo's API.
