10/28/2026, 3:09 PMdiscover_schema endpoint operates on the source, not the destination. Calling it with a destination ID is likely why you're not seeing updates — it's designed to discover the source schema. [Forum Post] • For data activation destinations, schema is managed by mapping source fields to destination fields within the connection's Mappings tab. The destination schema (e.g., HubSpot fields) is typically fetched from the destination connector itself when the connection is set up. [Add a Connection] What you can try: 1. Navigate to your connection in the UI. 2. Click the Mappings tab — this is where schema configuration lives for data activation connections. 3. If you need to update mappings, modify them there and click Submit. If the destination schema (e.g., new fields added to your destination) isn't reflecting in the Mappings tab, the knowledge sources don't explicitly document a way to force-refresh the destination schema via API. I'd recommend reaching out to Airbyte support or checking the Airbyte community for guidance specific to your destination connector. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.Alasdair Ellis
