How to Integrate Grinfi with Clay: Two-Way Data Exchange in 6 Steps

Clay and Grinfi are two powerful automation tools for sales teams. They perfectly complement each other: Clay for data enrichment and customization, Grinfi for smart outreach and funnel management.

While we’re waiting for the official integration with Clay, you can already set up a fully automated two-way lead exchange – here’s how to do it.

Sending Leads from Grinfi to Clay for Enrichment

Step 1. Create a Webhook in Clay

In your Clay workspace, open the table where you want to receive leads, and create a new webhook through the Actions → Webhook.

You will receive a unique URL – this will be used in Grinfi.

Step 2. Create a Webhook in Grinfi

Go to Grinfi Webhooks and click “Create Webhook”. Paste the URL you got from Clay.

Select a trigger – for example, Contact Export (Custom Call), which is the standard export webhook.

Step 3. Start Sending

You can:

• send manually from CRM using the “Export” button
• or set up automatic sending in an automation workflow

In Clay, the lead will land in the selected table – and you’ll be able to launch enrichment: social profiles, email lookup, company data, name adjustments, and more.

Step 4. Create Custom Fields in Grinfi (Optional)

If you added new fields in Clay (for example, a custom message or extra company info), create corresponding fields in Grinfi here: Grinfi Custom Fields

If you only updated standard fields (name, company, industry) – no additional steps are required.

Step 5. Create an API Key in Grinfi

On the Grinfi platform, go to Grinfi API Keys and create a new key for Clay.

Step 6. Configure a POST Request in Clay

In Clay:

• Open the HTTP API section
• Create HTTP API (Headers) account

Key: Authorization
Value: Bearer {Your Grinfi API Key}

• Create a new action with the POST method
• Endpoint: https://leadgen.grinfi.io/leads/api/leads/upsert
• The request body should look like this:

{
  "list_uuid": "YOUR LIST UUID",
  "lead": {
    "linkedin_id": "LinkedIn Profile",
    "first_name": "First Name",
    "last_name": "Last Name",
    "headline": "",
    "position": "Job Title",
    "company_name": "",
    "domain": "Company Domain",
    "email": "",
    "raw_address": ""
  },
  "custom_fields": {},
  "update_if_exists": true,
  "move_to_list": false
}

⚠️ IMPORTANT! The variables here are not just text. You need to select the correct variable by starting to type “/”
