Step 2: Connect the Transcript Fetch Service

Pull the TikTok captions using Dumpling AI and store the raw VTT text in the response body.

1. Open Dumpling AI Transcript Fetch and set URL to =https://app.dumplingai.com/api/v1/get-tiktok-transcript.
2. Set Method to POST and enable Send Body.
3. Under Body Parameters, set videoUrl to {{ $json['Tiktok Video URL'] }}.
4. Under Options → Response, set Response Format to text and Output Property Name to body.
5. Credential Required: Connect your httpHeaderAuth credentials.

Step 3: Set Up Transcript Cleaning and Parallel AI Analysis

Clean the VTT captions and run two AI analyses in parallel for insights and marketing rewrite.

1. Open Clean VTT Caption Text and set Mode to runOnceForEachItem.
2. Paste the provided JavaScript into JS Code to strip timestamps and return transcript.
3. Confirm the parallel routing: Clean VTT Caption Text outputs to both GPT-4 Insight Extraction and GPT-4 Marketing Rewrite in parallel.
4. In GPT-4 Insight Extraction, keep the Text prompt that references {{ $('Capture TikTok URL & Product').item.json['Keyword '] }} and {{ $json.transcript }}.
5. In GPT-4 Marketing Rewrite, keep the Text prompt that references {{ $('Capture TikTok URL & Product').item.json['Keyword '] }}, {{ $('Capture TikTok URL & Product').item.json['Product '] }}, and {{ $json.transcript }}.
6. Open GPT-4 Model for Research and set Model to gpt-4o-mini.
7. Credential Required: Connect your openAiApi credentials in GPT-4 Model for Research.
8. Open GPT-4 Model for Rewrite and set Model to gpt-4o-mini.
9. Credential Required: Connect your openAiApi credentials in GPT-4 Model for Rewrite.
10. 🧠 Agent Tools Hub and 🧠 Agent Tools Hub 2 are tool sub-nodes for the agents—if you add credentials for tools later, attach them to the parent agents (GPT-4 Insight Extraction and GPT-4 Marketing Rewrite), not the tool nodes.

Step 4: Configure Insight Parsing and Google Sheets Output

Parse the AI insight sections and append/update a Google Sheet with both insights and rewritten script.

1. Open Split Insight Sections and keep the provided JS Code and Instructions to extract pain points, outcomes, triggers, and quotes.
2. Open Update Sheets with Insights and set Operation to appendOrUpdate.
3. Set Document to the file named TikTok URL and Sheet to Sheet1 (gid=0).
4. Under Columns → Mapping, confirm the field mappings:
   • Video URL → {{ $('Capture TikTok URL & Product').item.json['Tiktok Video URL'] }}
   • New Script → {{ $json.output }}
   • Pain points → {{ $('Split Insight Sections').first().json.painPoints}}
   • Desired outcomes → {{ $('Split Insight Sections').first().json.desiredOutcomes }}
   • Original Transcription → {{ $('Clean VTT Caption Text').item.json.transcript }}
   • Interesting direct quotes → {{ $('Split Insight Sections').first().json.quotes}}
   • Triggers or motivating events → {{ $('Split Insight Sections').first().json.triggers }}
5. Set Matching Columns to Video URL so rows update on the same TikTok link.
6. Credential Required: Connect your googleSheetsOAuth2Api credentials.

Step 5: Test and Activate Your Workflow

Run a manual test to confirm the transcript fetch, AI outputs, and sheet updates work end-to-end.

1. Click Execute Workflow and submit the Capture TikTok URL & Product form with a valid TikTok URL, keyword, and product.
2. Verify Dumpling AI Transcript Fetch returns a body field and Clean VTT Caption Text outputs a transcript.
3. Confirm the parallel branch completes: GPT-4 Insight Extraction and GPT-4 Marketing Rewrite both return outputs.
4. Check Update Sheets with Insights for a new or updated row that includes insights and the rewritten script.
5. Toggle the workflow to Active so the form trigger runs in production.
