Send to n8n sends data to an n8n webhook to trigger workflows.
Before you start
Account: none. There is nothing to connect.
You need: the URL of the n8n webhook that should receive the data. It is required. The row needs no particular column.
Important: Send to n8n writes outside Loopster. With Auto-run on, new values in the first column trigger the row workflow, so data can be sent without you clicking run. Add the column without running it and test one row first. See Run columns safely: Auto-run, test one row, then run the rest.
Do I need to connect n8n?
No. n8n has no account to connect in Loopster.
How do I send rows to n8n?
Click Add column, then Add enrichment.
Open the Export tab. Under Automation, click Send to n8n.
Paste the webhook URL into the URL setting.
Check the body. It starts as
{}. Change it to the data you want to send. Where a field offers a column list when you press/or@, click a column to use its value. See Map an enrichment's inputs.Click the arrow next to the main button and choose Add column without running.
Click the play button on one row, then double-click the cell to read the result.
Check the result in n8n too.
To run the rest, click the play button on the column header and choose Run all N empty rows in the Run column dialog.
How do I check it worked?
Double-click a cell.
The details show the fields of the result. Hover a field and click Add to column to put it in its own column. See Put a result's fields into their own columns.
Also check the result in n8n.
Troubleshooting
Quick answer
Auto-run is off, or the column was added without running.
A required input or setting has no value (the panel footer warns).
The cell says Error: open it and read the message.
Nothing happens, or the cells stay empty
What you see: The column exists, but no row has run.
Why it happens: Auto-run is Off (the app says "New rows and values will not run on their own"), or you chose Add column without running.
What to do: Click a row's play button, or use the column header's Run column dialog. See Why didn't my column run?.
The footer says "Select a column for … before running"
What you see: A warning such as "Select a column for … before running." in the panel footer.
Why it happens: A required input or setting (marked with *) has no value. An input can be empty even when a suggestion names a column.
What to do: Click the input, press / and pick a column from the list. Do not close the list with Esc: a / or @ is then left in the field as plain text.
My cells say Skipped
What you see: Skipped in the cells.
Why it happens: Skipped means "Did not run because of filters or missing dependencies."
What to do: Double-click the cell and read the message. Check that every input is mapped to a column, and look under Run Settings for Add run condition ("Only run if this formula resolves to true.").
My cells say Unsatisfied
What you see: Unsatisfied in the cells.
Why it happens: Unsatisfied means "Enrichment ran correctly, but output didn't match expected format."
What to do: Double-click the cell and read the message. Check the input values in that row, and test one row before you re-run many. See What a cell's message means.
A cell says Error
What you see: The cell says Error, and the footer shows a count such as "1 cell failed".
Why it happens: Error means "Crashed, something went wrong." The message is in the cell it happened in.
What to do: Double-click the cell and read the message. Check n8n before you re-run, because a re-run runs the action again.
The result did not change after I edited an input
What you see: A finished cell keeps its old result after you change an input.
Why it happens: With Auto-run on, Keep existing results is ticked: "Only errored, empty and new cells run. A completed answer is left alone even when one of its inputs changes."
What to do: Double-click the cell and click Re-run this cell, or click the play button on the column header and choose Overwrite all N rows in the Run column dialog. Read the line under each option first. Either one runs the action on n8n again.
n8n got the same data twice
What you see: Repeated changes or duplicate entries in n8n.
Why it happens: This action writes outside Loopster. Re-run this cell and Overwrite all N rows run it again, so n8n may receive the data again.
What to do: Test one row first and check it in n8n. Keep Auto-run off until the first row looks right.
What does it cost?
Send to n8n is free. The panel shows Free, and the Run column dialog says Spends nothing from your wallet. See Your wallet and keeping spend under control.
