# Trending post

<Warning>
  **Limited availability:** This trigger is rolling out to selected organizations. If you don't see **Trending Post** in the trigger panel, it isn't enabled for your organization yet — reach out to [support@overlap.ai](mailto:support@overlap.ai) to request access.
</Warning>

> Runs your workflow automatically when a post you published starts trending — outperforming your account's own typical views. The workflow receives the trending post's clip, so you can send a proven winner to your other platforms the moment it takes off.

<Info>
  ### Schema

  * **Input**: None (this is a trigger)
  * **Output**: The trending post's clip, ready for editing or export nodes such as **Post to Social**
</Info>

## What counts as trending

Overlap scores every recent post hourly against your account's own baseline — how the post's views, view velocity, and engagement compare with what your account typically gets on that platform. A post becomes trending when it clearly breaks out of that baseline.

This trigger watches those trending posts and fires your workflow with the underlying clip. On top of Overlap's own trending detection, a post must also be at least 3x the account's typical views and at least 1,000 views before it can fire — fixed floors that cannot be configured or loosened per workflow.

## Add the node

Open **Workflows** from the left sidebar and click **New** to open the workflow builder.

Choose **Trending Post** from the trigger panel — it appears only for organizations the trigger has been enabled for. Connect it to the rest of your workflow — the most common pattern is straight into **Post to Social** for the platforms you want the winner republished to.

## Settings

* **Which platforms to monitor** — select one or more platforms to react to. Leave everything unselected to watch all platforms.
* **Allow duplicate posting** — off by default, so the trending clip is never re-posted back to the platform it already trended on.

## How often it triggers

Each post triggers the workflow **at most once**. If the same clip later trends again as a separate post — for example, on another platform — that counts as its own event and can trigger the workflow again.

## How it pairs with Post to Social

The clip that reaches your **Post to Social** node is the exact clip that went trending — the same cut, not a re-edit. Enable **Prevent Double Posting** in the Post to Social node's cadence settings so the workflow never re-posts to a platform that clip is already on.

## Notes

* Trending detection runs hourly; the trigger check runs shortly after, so a trending post typically fires its workflow within the hour.
* Deactivating the workflow removes the trigger's subscription — it stops firing immediately.
* The trigger remembers which posts it has already fired for, across config edits.
