Fetch OpenSea collection offers from a filtered Google Sheets range
Your filtered view already isolates the collections that matter this week. Notis takes it further by pulling every active OpenSea offer for whatever the filter surfaces, so you can gauge demand without touching OpenSea.
Trigger
Filtered Range Values Changed
Polling trigger that monitors Google Sheets filtered ranges for value changes. Uses snapshot-based diffing to detect when values matching a data filter change. Emits the matched values when changes are detected.
Action
Get all offers by collection
Get all active, valid offers for the specified collection. this includes individual and criteria offers.
Why this helps
Your filter shows you what to focus on, but checking real buyer demand still means manual OpenSea trips for each collection.
- See real buyer demand for whatever your filter surfaces
- Offers refresh automatically as your filtered view changes
- Skip the repetitive OpenSea checks for each collection
- Let your existing filter drive where Notis looks
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and OpenSea to Notis once from the portal.
- 2Create a New Automation named something like Filtered view to OpenSea offers.
- 3Tell Notis: when the values in my filtered range change, fetch all active OpenSea offers for the matched collection and report them.
- 4Select the Filtered Range Values Changed trigger and choose the channel for results.
- 5Change your filter so the range updates, then confirm the offers come back.
Questions about this workflow
Does this include criteria offers?
Yes. Notis fetches all active offers for the collection, including individual and criteria offers.
How does the filter connect to the automation?
Notis watches your filtered range and reacts when its matched values change, using your instruction to know which collection to look up.
Can I get just a summary?
You can ask Notis in plain language to summarize the offers rather than list them all, and it will report accordingly.
