Pipedream Anthropic (Claude) steps in n8n

Pipedream's Anthropic app is small: a Chat action and a helper that lists models. Most workflows that use Claude on Pipedream do it in a Node.js code step with the Anthropic SDK or a plain fetch. Both paths have a clear home in n8n: the native Anthropic node, or a Code / HTTP Request node with the Anthropic credential.

The n8n Anthropic node

n8n-nodes-langchain.anthropic:

Resource	Operations
Text	Message a Model
Document	Analyze Document
Image	Analyze Image
File	Upload File, Get File Metadata, List Files, Delete File
Prompt	Generate Prompt, Improve Prompt, Templatize Prompt

For agent-style workflows, n8n also has the Anthropic Chat Model sub-node that plugs into the AI Agent node. There is no Anthropic trigger.

What maps where

Pipedream (app anthropic)	In n8n	Status
Chat	Anthropic → Text → Message a Model	manual, 1 node
List Model Options	not needed; pick the model in the node	drop
Code step with @anthropic-ai/sdk	Code node; SDK listed as an npm package in the report	automatic, review
Code step with fetch('https://api.anthropic.com/v1/messages') and this.anthropic.$auth.api_key	Code node; key becomes the variable ANTHROPIC_API_KEY	automatic
Code step using axios from @pipedream/platform	Code node using this.helpers.httpRequest	automatic

The npm question matters here. n8n Cloud does not allow external npm modules in the Code node; self-hosted n8n allows them only when NODE_FUNCTION_ALLOW_EXTERNAL lists the package. If a code step imports @anthropic-ai/sdk, either allow it on your server or replace the step with the Anthropic node or an HTTP Request node. The report flags each case.

Credentials

1. Create a key in the Anthropic Console.
2. n8n: Credentials → New → Anthropic, paste the key. A custom header is optional.
3. On n8n Cloud you can use "Use Gateway credits" instead of your own key.

Pipedream never exports the key, so this step is always manual.

Typical migration: summarise long emails

Pipedream: Gmail New Email → code step (Anthropic SDK, messages.create) → Slack. n8n: Gmail Trigger → Anthropic (Message a Model, system prompt copied from the code) → Slack. Three nodes, no npm package to allow.

Pitfalls

• Output shape. Pipedream's Chat action and the raw API return content[0].text; the n8n node returns its own structure. Check the expressions in the steps after it with one test run.
• Rate limits. Anthropic limits requests per minute and input and output tokens per minute per model class, with a token bucket. A 429 may carry retry-after; a spend-limit 429 does not. Loops over many items need a Wait node or batching.
• Model names. Copy the exact model ID the Pipedream step used; aliases change over time.
• Long documents. For PDFs use Document → Analyze Document instead of pasting text into the prompt.

How to move your Anthropic workflows

1. Export the workflows from Pipedream.
2. Upload on /convert; the free report shows which Claude steps are code (automatic) and which are actions (manual).
3. Download the n8n JSON: 1 workflow is free; full export: $3 per workflow, $19 minimum — coming soon.
