Why n8n teams add DumplingAI
Data built for n8n workflows
Run OCR and image analysis on demand without maintaining vision pipelines.
Combine extracted text with n8n’s Function, AI, and Code nodes to classify, moderate, or summarize visuals.
Distribute alt text and annotations to destinations like Notion, databases, Slack, or vector stores instantly.
Integration overview
How the n8n + DumplingAI workflow fits together
Use the HTTP Request node to call DumplingAI’s Image Extraction endpoint with your asset, then pass the OCR text, labels, and descriptions deeper into the workflows.
Integration steps
- 1
Add the HTTP Request node
Insert an HTTP Request node after your trigger so you can call DumplingAI inside the workflow.
- 2
Configure the DumplingAI request
Switch the node to POST, attach your Header Auth credential, and define the JSON body in the Body Parameters section. Pass a publicly accessible image URL or encoded binary data and specify whether you need text, labels, or both.
- 3
Distribute the annotations
Send the response into Set, Function, or AI nodes before handing it off to other services. Hand the extracted text and tags to moderation flows, alt-text generators, or asset management tools.
Workflow ideas
Automations powered by Image Extraction data
Mix DumplingAI with n8n’s native actions to uncover new growth, enablement, and operations workflows.
Auto alt-text generator
Scan new creative assets, extract descriptive text, and push suggested alt copy into destinations like Notion, databases, Slack, or vector stores.
Content moderation guardrails
Run screenshots through the endpoint, flag risky terms with n8n’s Function, AI, and Code nodes, and alert review teams automatically.
Product catalog ingestion
Extract specs from packaging photos and append structured data to product records without manual transcription.
Technical checklist
Best practices before you deploy
Authentication
Store the DumplingAI API key in an n8n Header Auth credential and reference it wherever you need it.
Request payload
Send a reachable image URL or encoded binary plus optional toggles for OCR, labels, and descriptions.
Scaling & retries
Leverage the Error Workflow or Wait/Retry nodes to recover from transient failures. Use Split In Batches or Rate Limit nodes when you iterate over large queues.
Resources

Answers before you connect n8n to DumplingAI
How do I store the DumplingAI API key in n8n?
Store the DumplingAI API key in an n8n Header Auth credential and reference it wherever you need it.
Can I analyse multiple images in one workflow?
Use Split In Batches or Rate Limit nodes when you iterate over large queues. Loop through image batches with branch nodes or batching features.
What if the image cannot be fetched?
Confirm the URL is public or uploadable. DumplingAI returns descriptive errors so you can retry with valid assets.
