Connect Weld to 1,000+ Apps with n8n

Installation

Install directly from your n8n instance. Works with both n8n Cloud and self-hosted.

1. 1

   Open Community Nodes

   In n8n, go to Settings → Community Nodes → Install.

2. 2

   Enter the package name

   Type n8n-nodes-weld and click Install.

3. 3

   Restart if self-hosted

   n8n Cloud handles this automatically. Self-hosted instances may need a restart for the nodes to appear.

Authentication Setup

Every Weld node requires a Weld API credential. You only need to set this up once.

1. 1

   Create an API key

   Log in to Weld, go to Settings → API Keys, and click Create Key. Copy the key (it starts with weld_).

2. 2

   Add credential in n8n

   In n8n, open any Weld node → click the credential dropdown → Create New. Paste your API key into the "API Key" field.

3. 3

   Test the connection

   n8n will automatically verify your key by checking your credit balance. A green checkmark confirms it works.

Available Nodes

Each platform has its own dedicated node with tailored input fields, URL validation, color-coded icons, and AI agent descriptions.

Per-Platform Scraper Nodes

Each node supports three operations: Create, Get, and Get Results.

Weld Jobs (Management Node)

The Weld Jobs node handles cross-cutting job management and credit operations.

Quickstart: Scrape LinkedIn Profiles

Build a workflow that scrapes LinkedIn profiles and outputs the data as individual n8n items.

1. 1

   Add a Weld LinkedIn Profiles node

   Search for "Weld LinkedIn" in the node palette and add it to your canvas.

2. 2

   Select Create operation

   This is the default. It creates a new scrape job.

3. 3

   Enter profile URLs

   Paste LinkedIn profile URLs, one per line. E.g. https://linkedin.com/in/satyanadella

4. 4

   Enable "Wait for Completion"

   Toggle this on to have the node poll until the job finishes and return each profile as a separate output item.

5. 5

   Connect to your destination

   Wire the output into Google Sheets, Airtable, a database, Slack — or any of n8n's 1,000+ integrations.

// Example output item (one per profile)
{
  "_jobId": "k57a8b3c9d0e1f2g3h4",
  "_scraperId": "linkedin-profiles",
  "name": "Satya Nadella",
  "headline": "Chairman and CEO at Microsoft",
  "location": "Redmond, Washington",
  "about": "...",
  "experience": [...],
  "education": [...]
}

Operations Reference

Create (Scraper Nodes)

Get / Get Results

Wait for Completion

When enabled, the node polls your job status at the configured interval until the job completes, then fetches all results and outputs each record as a separate n8n item.

1. 1

   Create job without waiting

   Use a scraper node with "Wait for Completion" off. It returns immediately with a jobId.

2. 2

   Schedule a check

   Use a Schedule Trigger (e.g. every 2 minutes) connected to a Weld Jobs → Get node.

3. 3

   Branch on status

   Use an IF node to check if status === "completed", then fetch results with Weld Jobs → Get Results.

If the job doesn't complete within the max wait time, the node returns a timeout object with the jobId so you can check later.

AI Agent Compatibility

When used with n8n's AI Agent node, the LLM can select the correct scraper based on the user's request. Each node's description is written to minimize ambiguity — the agent won't confuse LinkedIn Profiles with LinkedIn Posts.

Error Handling

The nodes handle transient failures automatically and surface clear error messages for issues you need to fix.

Automatic Retries

HTTP 5xx, 429 (rate limit), and network errors are retried up to 3 times with exponential backoff (2s, 4s, 8s).

Continue on Fail

Enable Continue on Fail in node settings to convert errors into output items with an error field instead of stopping the workflow.
