Liner Zapier integrationAutomate Liner with Zapier.
The Liner Zapier integration gives you 0 triggers, 5 actions and 0 searches. Liner never starts a Zap on its own: another app does, then Liner answers a question with sources, runs a deeper research job or searches the web and academic papers for you.

What the Liner Zapier integration does for you
Liner is a search engine run by AI: it reads the web or scholarly sources and hands back an answer with its citations. Through Zapier, a question typed somewhere else can reach Liner without anyone copying and pasting it. The page of Liner on Zapier lists five actions and nothing else, and the app works on the free plan.
A sourced answer to every incoming question. A question lands in a form, and Run Quick Answer Agent returns a short factual reply backed by sources, ready to be sent on by the next step.
A research brief with citations. For a broader question, Run Deep Research Agent works through several steps and comes back with a report whose claims point to their sources.
A list of papers or pages, not an essay. Search Scholar returns academic results with their citation details, and Search Web returns public pages with title, snippet, URL, host and date.
What Zapier cannot do with Liner: start anything. There is no Liner trigger, so every Zap begins in another app, and there is no search step to look up a past answer either. So no later Zap can pick a result up again unless a step in the same run stores it somewhere. If you are still choosing a platform for this kind of workflow, see our n8n vs Zapier comparison.
Zapier words you will meet on this page
Seven terms, each in plain words. Once explained, they are used as is.
- Zap
- The automation you build in Zapier: one trigger, then one or more actions that run every time that trigger event happens.
- Trigger
- The event in an app that starts the Zap. Liner has none, so with Liner the trigger always comes from another app.
- Action
- What the Zap does once it has started. All five Liner operations are actions: they take a question and return results.
- Task
- The unit Zapier bills: one action your Zap completes successfully. The allowance on your plan is counted in tasks.
- Polling vs instant
- A polling trigger is checked by Zapier on a timer. An instant trigger is pushed by its app the moment the event happens.
- Filter
- A step that lets the Zap go on only when the incoming data meets your condition, and stops it there otherwise.
- Connection
- Your Liner account linked to Zapier once, then offered to every Liner step in every Zap you build.
What a Liner Zap really costs
Zapier bills tasks, and only successful actions create them. With Liner, that means every answer or search that comes back.
- Premium appNo, Liner runs on the free plan
- Free plan100 tasks a month, two-step Zaps
- Liner triggersNone, start from another app
- Failed actionNot billed
The trigger of the other app is free, however often Zapier checks it. Each Liner action that succeeds counts one task, and so does each later step: a form, a quick answer and an email reply cost two tasks per run. A failed action is not charged. The free plan gives 100 tasks a month and two-step Zaps only, which is enough for a trigger plus one Liner action. The grid below applies to the trigger app when its trigger is a polling one; an instant trigger ignores it.
Connect Liner to Zapier in three steps
- 01
Open your connections
In Zapier, open the Apps page of your account and click + Add connection. You need a Liner account first; anything you want the Zap to reach that you do not own also needs your access.
- 02
Pick Liner
Type Liner in the search box of the dialog and select it from the results. Then click Add connection; a new browser tab opens on the Liner sign-in screen, ready for your login.
- 03
Sign in and grant access
Log into Liner in that tab and allow Zapier to use the account. The connection is saved once, and each Liner step you add later offers it in its account menu.
Your first Zap: a sourced answer to every form question
GoalEach time someone asks a factual question through your form, Liner writes a short answer backed by sources, and your team chat receives it.
- 01
Pick the starting event
Create a Zap and choose your form tool with its new submission event as the trigger, since Liner has none. Test it: Zapier brings back the three most recent entries so you map from a real one.
- 02
Add Run Quick Answer Agent
Add a Liner step and pick Run Quick Answer Agent. Map the question field of the form into Question. That is the only field the action insists on.
- 03
Post the answer
Add a step in your team chat that sends the answer Liner returned. This third step makes the Zap multi-step, so it needs a paid plan; on the free plan, stop after Liner.
- 04
Test, then publish
Run each step once and read the answer that came back, sources included. When it looks right, publish the Zap to switch it on. Only questions sent after that moment will start it.
Liner actions
Liner gives you 5 actions. For each one: what it does for you, when to reach for it, and what to watch out for.

When a Liner Zap breaks
Zapier links no help article to Liner, and no app-specific limit is documented. What breaks comes from how Zapier itself works, mostly around the trigger app.
Four cases explain most surprises. When one hits, our Zapier troubleshooting page is the place to start.
Older questions are never answered
A Zap only reacts to what happens after you switch it on. Questions that were already in your form or sheet stay out, and processing them is a separate job.A Zap that answers itself forever
If the Zap writes Liner's answer into the very sheet its trigger watches, each new row sets it off again, and the task count drains fast.A sudden flood is held back
When the trigger app suddenly returns a huge batch, after a bulk import for example, Zapier's flood protection can hold those runs back.The same question is not sent twice
On a polling trigger, Zapier remembers what it has already seen, so an entry it handled once does not reach Liner a second time.
