Create Popup
Create a saved popup and get the one-line script tag that deploys it. The popup
is published by default, so the script is live as soon as it is added to the
site. Trigger, targeting, audience, and duplicate handling stay server-side, so
the deployed script carries no API key.

When the popup opens:
{ "type": "delay" | "scroll" | "exit-intent" | "click" | "manual", "delaySeconds": 0-3600, "scrollPercent": 1-100, "clickSelector": "#join" }. A click trigger requires a clickSelector.object
Where it may show:
{ "domains": [], "paths": [], "excludedPaths": [], "device": "all" | "desktop" | "mobile" }. Empty arrays mean no restriction.object
Optional run window:
{ "startsAt": "2026-09-01T00:00:00Z", "endsAt": "2026-09-08T00:00:00Z" }. endsAt must be later than startsAt.object
How often one visitor sees it:
{ "maxDisplays": 1-100, "windowDays": 1-365 }.object
Media panel and urgency treatment:
{ "style": "none" | "accent" | "header" | "rail" | "image" | "countdown", "placement": "top" | "left" | "center" | "right", "imageUrl": "https://...", "imageAlt": "...", "countdownMinutes": 1-10080 }. The image style requires an https imageUrl - the image panel is
painted as a background, so a missing or blocked image would leave an empty
column beside your content.object
Visual theme overrides:
accentColor, backgroundColor, textColor,
mutedTextColor, cardColor, borderColor (all #rrggbb), borderRadius
(0-32), headingFontFamily, bodyFontFamily, density.object[]
Complete replacement for the popup’s content blocks. The popup must keep
exactly one required email field and one submit button. See Content
blocks for each kind’s
properties.
