Sync ABM Lists to LinkedIn Ads

Prerequisites

• LinkedIn Campaign Manager account
• ABM target company list (from Attio or Clay)
• LinkedIn Marketing API access

Steps

1. Prepare your ABM list. Create a CSV with company names (required), company domains (recommended), and optionally company LinkedIn page URLs. Export from Attio using the MCP or API.

2. Upload via LinkedIn Marketing API. Use the API to create a matched audience:

   POST /v2/dmpSegments
   { "name": "Q1 Target Accounts", "type": "COMPANY", "destinations": [{"destination": "LINKEDIN"}] }
   

   Then upload the company list. LinkedIn matches companies to profiles -- this takes 24-48 hours. Aim for 80%+ match rate.

3. Improve match rate. If match rate is low, add more data points: include both company name variations and domains. Re-upload with enriched data.

4. Automate Attio-to-LinkedIn sync. Build an n8n workflow: Schedule Trigger (weekly) -> Attio MCP (export target account list) -> Code node (format as CSV) -> HTTP Request (upload to LinkedIn Marketing API). This keeps your LinkedIn audience in sync with your CRM.

5. Create targeted campaigns. Use the matched audience in campaign targeting via the API. Layer job function and seniority filters on top to reach only decision-makers at target accounts.

6. Measure ABM campaign performance. Track via the LinkedIn API: impressions, engagement, and pipeline generated from target accounts. Sync to PostHog via n8n for unified reporting alongside organic metrics.
