Innovid's Flashtalking ad server accepts HTML5 creatives prepared for Creative Manager. A zip carries a root manifest.js declaring the entry file, dimensions and click count, and the HTML binds exits through the Flashtalking HTML5 API (current 2.10). We avoid external CDNs by default; Flashtalking hosts a set of common libraries but its allowlist is not published. No total ZIP size cap is stated: ad weight is judged per size against IAB initial-load and subload thresholds.
Also known as Flashtalking, FlashTalking, Flashtalking by Mediaocean, Innovid Creative Manager.

Official requirements Also from Flashtalking (Innovid): Flashtalking-HTML5 API 2.10 (CDN), Flashtalking-hosted HTML5 example, GroupM Nexus trafficking spec (Flashtalking HTML5 section), Innovid Creative Development training, Innovid display specification (no stated total-ZIP cap), Flashtalking Creative Manager help — Uploading Creatives (sign-in required), Flashtalking Standard Ads spec (sign-in required), Innovid Help Center (sign-in required).
Flashtalking (Innovid) requires its own library in the document. Foldwrap adds it automatically on export.
<script src="https://cdn.flashtalking.com/frameworks/js/api/2/10/html5API.js"></script>Path is versioned as /api/<major>/<minor>/html5API.js. Version 2.10 is current and 2.9 still resolves; the GroupM spec's /api/v2/10/ path returns 404. The API version baked into a creative must keep matching the version declared in manifest.js.
These are the rules Foldwrap checks a package against before it is delivered to Flashtalking (Innovid). Each is derived from the requirements above, so a constraint Flashtalking (Innovid) does not state is not checked and is not listed.
Foldwrap runs these checks on every package it exports for Flashtalking (Innovid), and names the creative and the constraint when one fails.
Every figure above, with the document it came from and the date we read it.
The HTML and manifest.js files must be located in the root directory of the HTML5 creative.

Do not link to external CDNs. Instead, package a minified version of the library with the rest of your files... There is an allowlist of CDNs, a denylist of CDNs, and a selection of commonly used libraries hosted by Flashtalking.
