n8n LinkedIn Lead Enrichment with MasLeads API Workflow

Enrich LinkedIn leads on demand with MasLeads API—inside n8n

This n8n LinkedIn Lead Enrichment with MasLeads API workflow lets you manually submit a LinkedIn profile to the MasLeads API, automatically poll until the enrichment is complete, and then return the results (or stop with a detailed error if something goes wrong).

What this workflow does

• Manual trigger: Starts when you run the workflow manually in n8n.
• Input setup: Sets required inputs—LinkedIn URL, the enrichment field you want to retrieve (e.g., "email"), and an external ID.
• Account usage check: Calls the MasLeads API to check your account usage and available balance/credits.
• Create enrichment job: Submits the LinkedIn lead to MasLeads to create an enrichment job, using an idempotency key to avoid duplicate submissions.
• Wait-and-poll loop: Waits 30 seconds, checks job status, and repeats until the job completes.
• Fetch results: Once complete, requests the enrichment output from MasLeads and returns the enriched lead data.
• Failure handling: If the job is blocked or fails, the workflow stops and raises an error including the status details.

Use cases

• Sales and outreach ops: Enrich a LinkedIn profile to retrieve a specific field (such as email) before contacting a prospect.
• Lead management cleanup: Validate and augment lead records in your system using MasLeads enrichment results.
• Automation engineers: Add a reliable LinkedIn enrichment step into an existing n8n workflow, with clear status/error reporting.
