Create OpenSea item offers when a Google Sheets row changes
You track the NFTs you want and the price you are willing to pay in a sheet. When you revise that number, remembering to go re-bid on OpenSea is where it slips. Notis watches the row and updates your offer for you.
Trigger
Spreadsheet Row Changed
Triggers when a looked-up spreadsheet row changes. This trigger monitors a specific row (located by searching for a query value within a user-specified range) and fires when the row's values change, when the row appears, or when the row disappears.
Action
Create item offer
Create an offer to purchase a single nft (erc721 or erc1155).
Why this helps
Your bidding plan lives in a spreadsheet, but keeping actual OpenSea offers in step with it means constant manual re-bidding.
- Your live OpenSea offer always reflects the number in your sheet
- No more forgetting to update a bid after you change your mind
- Plan your buying calmly in a spreadsheet and let Notis execute
- One row edit replaces a trip to OpenSea every time
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and OpenSea to Notis once from the portal.
- 2Create a New Automation in the portal and name it something like Target price to OpenSea offer.
- 3Give Notis the instruction: when the target-price row for an NFT changes in my sheet, create a matching offer to buy that NFT on OpenSea.
- 4Choose the Spreadsheet Row Changed trigger and set the channel where Notis reports each offer.
- 5Edit one row as a test and verify the offer reflects your new price.
Questions about this workflow
How does Notis find the right row?
You describe how to locate the NFT, for example by a name or id in a column, and Notis watches that row for changes. No manual field mapping is involved.
Can it react to any cell in the row?
Yes. The trigger fires when the row's values change, and your plain-language instruction tells Notis to act on the price you care about.
Is there a record of each offer?
Notis sends a run report to your chosen channel every time it places an offer, so you have a clear trail.
