Zapier has had the ability to search and update existing records in other apps like Google Sheets, Airtable etc. for a while now. It would be great to see the ability to update an existing Knack record via Zapier action enabled.
This would also need a search Action as well - to locate the record you need to update.
I agree. This would be great. The more SAAS that pops up, the more valuable this feature becomes. I can think of multiple use cases in my own circumstances!
