Send daily TikTok trend digests to Telegram using WayinVideo and GPT-4o-mini

Description

Add TikTok video URLs to a Google Sheet and every morning at 8AM the workflow automatically processes each one, skipping cleanly if nothing is queued. [WayinVideo](https://wayin.ai/api/) summarizes each video, then all summaries are combined and sent to GPT-4o-mini in one call which writes a 5-section daily digest — trend overview, per-video summaries, top 3 content patterns, action recommendations, and trending tags. A formatted Telegram message is sent to your team channel with auto-truncation at 4000 characters, and everything is logged to Google Sheets. Built for social media teams, content agencies, and brand managers who want to track what is trending in their niche every morning without watching hours of videos.

What This Workflow Does

- Stops cleanly when the queue is empty — An early IF check detects whether there are any pending videos and exits gracefully if there are none — no errors, no failed runs - Summarizes each TikTok video via WayinVideo — Each video URL is submitted to WayinVideo's Summarization API which returns a structured summary, key highlights, and tags - Combines all video summaries before writing the digest — An aggregation step collects every processed video into one combined text block so GPT sees all the content at once - Writes a 5-section daily digest in one GPT call — GPT produces a trend overview, one-line summaries per video, top 3 content patterns, 2–3 action recommendations, and top trending tags - Sends a formatted Telegram message with auto-truncation — The digest is built in Telegram Markdown with section headers and emoji icons, auto-truncated at 4000 characters if it is too long - Logs the digest to Google Sheets — Overview, top patterns, action recommendations, tags, and send status are saved to the Digest Log tab for your records - Marks all processed videos in the queue — Every Video Queue row is updated with Processed status and today's date so the same videos are never processed again
