Automatic TikTok Reels Integration

My ecommerce app is built entirely in Flutter and I publish fresh product-focused TikTok reels every day. I want those reels to appear in the app automatically—no manual uploads, no copy-pasting links—so customers can watch, then tap straight through to buy or start a chat enquiry.

Here is what I’m looking for:
• A clean integration that pulls every new reel from my TikTok account the moment it is live (TikTok API, webhooks, or a smart crawler—whatever is reliable and within TikTok’s terms).
• Flutter-friendly widgets or components that stream the videos smoothly inside the app, with autoplay and full-screen options.
• Clear in-video or adjacent call-to-action elements that route users either to the relevant product page for purchase or to a pre-filled enquiry chat.
• Lightweight backend or middleware (Firebase, Node, or similar) so I can manage API keys securely and set how often the feed refreshes.
• A concise setup guide so I can redeploy the solution when I push future app updates.

Acceptance criteria: reels sync automatically without crashes, thumbnails and captions load correctly, CTA links open the intended screens, and the integration adds minimal load time to the existing app.

If you’ve linked TikTok with Flutter apps before—or have a clever workaround that meets TikTok’s policies—let’s talk.
