Lead webhook → ActiveCampaign + Notion

When a lead form submits, create or update a CRM contact in ActiveCampaign and append a row to a Notion database for your team to track. One webhook trigger drives both MCP calls in parallel after validation.

What you’ll build

Outcome: Marketing automation receives the lead immediately; sales sees the same submission in Notion with source and timestamp.

Prerequisites

project_contributor access
ActiveCampaign API URL and token
Notion integration token with target database shared to the integration
Notion database with properties: Name (title), Email (email), Source (select or text), Status (select, default New)
Inbound webhook subscription

Connectors to install

Adapter	Purpose
activecampaign	Create CRM contact and subscribe to list
notion	Log submission in team database

Build the workflow

Discover Notion database ID

Run mcp_call → notion_search and copy the database UUID for your leads table.

Create workflow

Name it lead-sync-ac-notion in Workflow Studio.

Validate input

lua_script requires email; normalize first_name, last_name, source.

Create ActiveCampaign contact

mcp_call → activecampaign_create_contact with optional field_values_json for custom fields.

mcp_call → notion_create_database_item in parallel (same depends_on as validate) or after AC — both are valid.

Subscribe to list (optional)

Add mcp_call → activecampaign_subscribe_or_unsubscribe_contact_from_list after contact creation.

Wire form webhook

Point your landing page form at the inbound webhook URL.

Validate input

{
  "id": "validate",
  "type": "lua_script",
  "name": "Validate lead",
  "script": "if not input.email or input.email == '' then error('email required') end\nreturn {\n  email = input.email,\n  first_name = input.first_name or '',\n  last_name = input.last_name or '',\n  source = input.source or 'website'\n}",
  "timeout_s": 10
}

ActiveCampaign contact

{
  "id": "create-contact",
  "type": "mcp_call",
  "name": "Create AC contact",
  "tool_name": "activecampaign_create_contact",
  "tool_args": {
    "email": "{{steps.validate.result.email}}",
    "first_name": "{{steps.validate.result.first_name}}",
    "last_name": "{{steps.validate.result.last_name}}",
    "field_values_json": "[{\"field\":\"1\",\"value\":\"{{steps.validate.result.source}}\"}]"
  },
  "depends_on": ["validate"],
  "timeout_s": 30
}

Replace field 1 with your ActiveCampaign custom field ID for lead source.

Notion log row

{
  "id": "log-notion",
  "type": "mcp_call",
  "name": "Log lead in Notion",
  "tool_name": "notion_create_database_item",
  "tool_args": {
    "database_id": "your-database-uuid",
    "properties_json": "{\"Name\":{\"title\":[{\"text\":{\"content\":\"{{steps.validate.result.first_name}} {{steps.validate.result.last_name}}\"}}]},\"Email\":{\"email\":\"{{steps.validate.result.email}}\"},\"Source\":{\"select\":{\"name\":\"{{steps.validate.result.source}}\"}},\"Status\":{\"select\":{\"name\":\"New\"}}}"
  },
  "depends_on": ["validate"],
  "timeout_s": 30
}

Use notion_retrieve_database to confirm exact property names and types before publishing.

{
  "id": "subscribe-list",
  "type": "mcp_call",
  "name": "Add to nurture list",
  "tool_name": "activecampaign_subscribe_or_unsubscribe_contact_from_list",
  "tool_args": {
    "contact_id": "{{steps.create-contact.result.contact.id}}",
    "list_id": "12",
    "subscribe": true
  },
  "depends_on": ["create-contact"],
  "timeout_s": 30
}

      "tool_args": {
        "database_id": "your-database-uuid",
        "properties_json": "{\"Name\":{\"title\":[{\"text\":{\"content\":\"{{steps.validate.result.first_name}} {{steps.validate.result.last_name}}\"}}]},\"Email\":{\"email\":\"{{steps.validate.result.email}}\"},\"Source\":{\"select\":{\"name\":\"{{steps.validate.result.source}}\"}},\"Status\":{\"select\":{\"name\":\"New\"}}}"
      },
      "depends_on": ["validate"],
      "timeout_s": 30
    },
    {
      "id": "subscribe-list",
      "type": "mcp_call",
      "name": "Add to nurture list",
      "tool_name": "activecampaign_subscribe_or_unsubscribe_contact_from_list",
      "tool_args": {
        "contact_id": "{{steps.create-contact.result.contact.id}}",
        "list_id": "12",
        "subscribe": true
      },
      "depends_on": ["create-contact"],
      "timeout_s": 30
    }
  ]
}

log-notion and create-contact both depend on validate, so they run in parallel after validation.

Idempotency

Duplicate webhook deliveries may create duplicate Notion rows. Mitigations:

Store submission_id in Notion and skip if notion_find_database_item finds a match
Use ActiveCampaign’s duplicate handling — update with activecampaign_update_contact when email exists

Variations

Add llm_call to score lead intent → activecampaign_add_tag_to_contact with hot / warm / cold.
Notify sales on Slack (when messaging tools ship) or Resend email for hot leads only.
Replace Notion with Google Sheets insert_row for a lighter log.
