  1. The Conversion Leads integration assumes that you are already downloading your leads and storing the Meta Lead ID in your CRM. This section provides an overview of how to download leads with Zapier and store the Lead ID.
    If you are already downloading Meta leads and storing the Lead ID in your CRM, skip to Step 1: Implement Conversion Leads Integration.

  2. Log into Zapier and create a new Zap using Facebook Lead Ads as the trigger app and your CRM as the action app.
    In this example, you create a new Contact in HubSpot when a new lead on Facebook is generated.

  3. Connect your Meta ad account to Zapier, then select the applicable page and lead forms when prompted.

  4. Zapier stores the Lead ID in the lead's id field. You can see the Lead ID in a test trigger where Zapier pulls in a lead from Meta.

  5. In the Zapier action app, store the Lead ID by mapping it to the standard Lead ID field in your CRM, or a custom field if it does not exist. In this example, you map the Lead ID to the Facebook Lead ID field in HubSpot, which is a custom field you create in HubSpot.
