Do I need a paid Zapier plan to use FishOut with Zapier?

Yes, on the Zapier side. Webhooks by Zapier is a premium app and a Free Zapier account cannot use a Catch Hook. The FishOut side is on every plan including Free, so if you would rather not pay Zapier, a plain webhook to your own endpoint does the same job.

How quickly does a mention reach my Zap?

As soon as the AI read is done and it clears the relevance floor. FishOut pushes to the Catch Hook, instantly rather than batched, which makes it an instant trigger — it does not wait for Zapier’s polling schedule, which is 15 minutes on Free and 2 minutes on Professional. The real ceiling is how often FishOut collects: hourly on every plan, and every 15 minutes on Reddit, Hacker News and Bluesky for keywords you mark Fast on a paid plan.

How many Zapier tasks will this use?

One per successful action step. The trigger itself is free — Zapier does not charge for receiving the hook — so the cost is whatever you do with the mention. That is why the relevance floor matters here in a way it does not on a chat channel: a floor of 40 instead of 70 can multiply the bill on a Zap you set up once and forgot about.

What happens if my Zap fails?

On a paid Zapier plan, Autoreplay retries the step up to five times over about ten and a half hours before emailing you. Watch for the other rule too: Zapier turns a Zap off by itself if it errors 95% of the time across seven days and has run more than 20 times in that window.

Can I verify the payload came from FishOut?

Not with a signature on the Zapier channel: like Slack and Discord, Zapier’s Catch Hook URL is itself the shared secret, so FishOut does not sign Zapier deliveries. If you need HMAC-SHA256 verification, add a webhook channel instead and point it at your own endpoint — or at a Catch Raw Hook, which hands you the headers and the raw body to verify in a Code step.

Is the Catch Hook URL a secret?

Zapier says to treat it as a password. It is hard to guess, but anyone holding it can trigger your Zap and burn your tasks. It stays the same for the life of the Zap unless the Zap is transferred to a different Zapier account, because the URL embeds the owner’s id.

Brand mentions into a Zap, already filtered

Zapier is the answer to "can it talk to the thing we use", where the thing is a CRM, a spreadsheet or a task tracker. FishOut posts to a Catch Hook, which makes it an instant trigger rather than a polled one — worth understanding, because it is the difference between seconds and a quarter of an hour.

[01] WHAT LANDS THERE/ A ZAP

A mention, as it arrives in Zapier

Rendered by the code that sends it, from a sample Reddit post. Never the post body.

POST — catch hook

{
  "version": 2,
  "id": "mention.scored:wrq_sample:reddit-shared-inbox",
  "type": "mention.scored",
  "organizationId": "org_acme",
  "projectId": "prj_default",

      ],

      "replyCall": "reply_now",
      "replyHint": "answer",

    }
  }
}

Zapier receives the same version 2 envelope as a webhook, unsigned — the Catch Hook URL is the secret. relevance, labelNames, replyCall and subject are all there to filter and map on. The post body is deliberately absent; links.self fetches it with your own API key.

[02] CONNECT IT/ SETUP

Point FishOut at a zap

4 steps, a few minutes end to end.

1
Add a Catch Hook trigger
In the Zap editor, make Webhooks by Zapier the trigger and choose Catch Hook for a parsed body, or Catch Raw Hook if you want the headers and the unparsed payload — which is what you need if you want to read our event-id headers.
2
Copy the hook URL
It appears in the Test tab with a Copy button. The URL is tied to the Zap and does not change, unless the Zap is transferred to another Zapier user — the URL carries the owner’s id. Zapier’s own advice is to treat it as a password.
catch hook url
```
https://hooks.zapier.com/hooks/catch/1234567/f8f22dgg/
```
3
Paste it into FishOut and set a floor
Under Settings → Notifications, add a Zapier channel, paste the URL and set a relevance floor. This is the channel where the floor is about money as much as noise: every successful action step downstream is a Zapier task. Zapier channels send each mention instantly rather than batching it into a digest.
4
Build the rest of the Zap
Send a test from FishOut so Zapier can learn the payload shape, then map the fields you care about — relevance, labelNames, replyCall, subject, platform, url — onto whatever comes next. The post body is not in the payload; fetch links.self with an API key if you need it. Free Zapier accounts are limited to a two-step Zap, so a filter plus an action needs a paid plan.

Then set the floor

On Zapier the relevance floor is a budget as much as a noise control. Triggers are free — Zapier does not charge for the poll or the catch — but every successful action step downstream is a task, so a floor of 40 rather than 70 can quietly multiply your monthly bill by a Zap you set up once and forgot. Set it where the downstream action is actually worth taking, and filter on labelNames or replyCall inside the Zap for anything finer.

[03] WHAT IS IN IT/ FIELDS

What Zapier receives, field by field

Built from the event’s envelope and nothing else, so a retry renders exactly the message the first attempt would have.

Field		How
relevance, relevanceReason	Shown	Filter on it in a Filter step if you want a second, Zap-side floor.
labelNames, labels	Shown	Display names and stable ids, in the same order.
replyCall, replyHint	Shown	Ids such as reply_now and answer; null where the platform has no Reply call.
title, url, authorHandle, postedAt	Shown	The title is the platform’s own, unclipped up to 300 characters.
links.self, links.app	Shown	The REST resource, and the mention in the FishOut inbox.
Post body	Never	Never sent: the envelope does not carry it.

[04] EVERY EVENT/ INSTANT

One request per event, by default

A machine wants every event and can group them itself, so Zapier channels send each one as it happens. The same event can arrive twice after a retry: key on the envelope id, which is also the x-fishout-event-id header. Opt into the digest if you would rather receive a mention.digest per window.

Request headers

[05] WHAT WILL BITE YOU/ LIMITS

Zapier’s limits, not ours

These are Zapier’s constraints and failure modes, checked against its own documentation. Its pricing and plan structure move often enough that we link to it rather than quote it. Failures are tracked per channel, so one broken destination never stops the others.

Webhooks by Zapier is a premium app and needs a paid Zapier plan. A Free Zapier account cannot use a Catch Hook at all — the FishOut side is on every plan including Free, but the Zapier side is not. [source]

Because FishOut pushes to the hook, this is an instant trigger and skips Zapier’s polling schedule entirely. That schedule is 15 minutes on Free and 2 minutes on Professional, so the difference is not academic. [source]

Triggers do not consume tasks — only successful action steps do. It is the step after the trigger that costs, which is what makes the relevance floor a billing setting here. [source]

A Zap is capped at 100 steps, and a Free Zapier account is limited to two — one trigger and one action. A filter counts as a step but not as a task. [source]

The maximum payload is 10MB for a trigger and 2MB for a Catch Raw Hook, headers included. A FishOut event is a couple of kilobytes, because the post body is never in it. [source]

On a paid plan Zapier replays a failed step up to five times, backing off from 5 minutes to 6 hours — about ten and a half hours end to end — before it emails you. Autoreplay is not available on Free. [source]

Zapier turns a Zap off automatically if it errors 95% of the time over seven days and has run more than 20 times in that window. A Zap that silently switched itself off is a common reason alerts stop. [source]

In the channel’s delivery history
You see	It means	Do this
http_404 / http_410	The Zap or its hook no longer exists, or the Zap is off.	Turn the Zap on, or copy the new Catch Hook URL into the channel.
redirect_not_followed	The URL answered with a redirect, which FishOut never follows.	Paste the hook URL exactly as Zapier shows it.
invalid_destination	The URL is not a hooks.zapier.com Catch Hook.	Use Webhooks by Zapier → Catch Hook, or a webhook channel for anything else.
