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.
Schema
- Input: None (this is a trigger)
- Output: The trending post’s clip, ready for editing or export nodes such as Post to Social
What counts as trending
Overlap refreshes each social account’s platform-specific 90-day baseline daily, then scores every recent post hourly against that history. An account-platform pair needs at least 20 historical posts before Overlap can make a reliable comparison; until then, it does not fall back to a company-wide average and does not send a trending notification. A post needs two analytics snapshots between 15 minutes and 12 hours apart. It must add at least the greater of 50 views or 5% of the account’s median, and it must have at least the greater of 1,000 total views or 50% of that median. Passing those evidence checks is not enough by itself: the post must also either reach the account’s historical 90th-percentile view count or reach its median while gaining views at least 5× faster than the account’s normal daily pace. Qualifying posts are ranked by a standout index that compares their p90 overperformance and their recent velocity. Overlap selects at most two new standout posts per company in any rolling 24-hour window. A selection that cools off stops appearing as actively trending, but its slot remains occupied until that 24-hour window expires so customers cannot receive a stream of ordinary-post alerts. This trigger watches the selected trending posts and fires your workflow with the underlying clip. It does not apply another threshold after trending detection.Email alerts
When Overlap selects a trending post, every active member of the organization who has Email notifications enabled receives the standout-post email. The email includes the clip thumbnail, aspect ratio, title, description, and current view, like, and share counts. Its link opens the trending post directly on the Analytics post-detail page and preserves the Posts tab and views sort as the return destination. An organization receives at most two trending-post emails in any rolling 24-hour period, one for each distinct standout post. Overlap sends no more than one email per hourly scan, starting with the highest-ranked standout that has not already used a slot. Each post is permanently marked after successful delivery, so a post that remains trending beyond 24 hours is not emailed again. Delivery retries reuse the same provider idempotency key, so an uncertain retry does not create a duplicate message. Email delivery starts with posts newly selected after live alerts are enabled; previously selected trending posts are not backfilled. If a saved member address is rejected by the email provider as invalid, Overlap skips that address permanently for the post. Valid opted-in recipients still receive the alert, and the invalid address does not leave the organization’s notification queue stuck retrying.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.
- Which accounts to monitor — select one or more connected accounts to react to. Leave everything unselected to watch all connected accounts.
- Allow duplicate posting — off by default, so the trending clip is never re-posted back to the account it already trended on. A second account on the same platform still receives the repost.
How often it triggers
The trigger fires at most once per clip, per account it trended on:- A post triggers the workflow at most once, and a post that stops trending and later trends again does not re-trigger it.
- Re-posts of the same clip to the same account (for example, scheduled intermittent reposts) count as the same event — the trigger will not fire again for them.
- The same clip trending on a different account is its own event and triggers the workflow again.
- Posts this trigger itself created never re-trigger it, no matter how well they perform — including any later scheduled reposts of them. This is what keeps a winning clip from looping through the workflow indefinitely.
Watching it run
Opening the workflow shows the usual launcher — the URL box, upload target and project picker — with Previous Runs beneath it. When one of your posts trends the trigger supplies the clip itself, so nothing needs to be pasted for those runs. You can also drop in a video by hand. A pasted link or uploaded file is run through the workflow as a single clip spanning the whole video: it is normalized, then handed to Post to Social exactly as a trending clip would be, so it is reposted to every account the workflow is configured for. Its card in Previous Runs readsManual → {platforms it was posted to}.
Each card in Previous Runs is one repost:
- the badge counts the accounts that repost went out to, rather than clips found
- the line beneath reads
{platform it trended on} → {platforms it was reposted to}as icons - clicking a card opens the clip that was reposted
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, and your workflow fires as soon as a post is detected as trending — there is no separate waiting step in between.
- A company can have at most two newly selected trending posts in a rolling 24-hour window.
- Email alerts go only to organization members who have email notifications enabled, with at most two trending emails per organization in a rolling 24-hour period.
- A specific post produces at most one live trending email, even if it continues trending or qualifies again after the rolling window resets.
- If that first attempt doesn’t go through, the post is queued and retried automatically over the following hour, so a workflow isn’t lost to a temporary hiccup.
- Building the workflow while one of your posts is already trending fires it right away, rather than waiting for the next check.
- 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.
