Export Conversions to Meta Ads with Vendo

Learn how to export conversions to Meta Ads from Mixpanel using an existing Meta Pixel, select an attribution model, and configure key settings for optimal performance.

How It Works

Vendo reads conversion events from Mixpanel
An attribution model matches conversions to Meta Ads clicks using the fbclid
Attributed conversions are sent to Meta via the Conversions API

Prerequisites

A Meta Business account connected in Vendo
A Meta Pixel or Dataset created in Meta
Your website captures and stores the fbclid click ID

Required Information

Mixpanel Conversion Event Name
Meta Dataset ID
Meta Access Token
Meta Conversion Name

1. Mixpanel Conversion Event Name

Select the event in Mixpanel that represents your conversion, such as “Purchase Completed” or “Lead Qualified.”

2. Meta Dataset ID

To use the Conversions API, you need either a Meta Dataset ID or Meta Pixel ID.

Log in to your Facebook Business Manager account
Navigate to the homepage and use the left-hand menu to click on the Data Sources tab
Copy your Dataset ID

3. Access Token

To use the Conversions API, you need to generate an access token, which is passed as a parameter in each API call.

Choose the Pixel you want to implement
Select the Settings tab
Find the Conversions API section and click on the Generate access token link under Set up manually
Follow the instructions in the pop-up

4. Meta Conversion Name

Meta requires conversions to be associated with predefined events. Select the conversion event name that is most relevant to your goals (e.g., Purchase, Lead, or Add to Cart).

Add the Conversion to a Campaign

Once your custom conversions are being tracked:

Create a new campaign and ad set in Meta Ads Manager
Select Website Conversion as the campaign objective
Choose the Conversion API event you’ve created to optimize your campaign

Configuration

Setting	Description	Default
Mixpanel Conversion Event	Source event to track	Required
Dataset ID	Meta Dataset or Pixel ID	Required
Access Token	Conversions API access token	Required
Meta Conversion Name	Event name sent to Meta	Required

Attribution Models

Choose how conversion credit is distributed. See Attribution Models for details on each model.

Click ID Tracking

Meta automatically appends the fbclid parameter to landing page URLs. Ensure your website captures and stores this parameter so Vendo can match conversions to ad clicks.

Conversion Payload

Each conversion sent to Meta includes:

Event Name — The configured conversion event name
Event Time — ISO 8601 timestamp

User Identifiers — Customer identifiers required by Meta (hashed where applicable)

Sync Details

Conversions are exported on a schedule and honor your lookback window

Troubleshooting

Authentication errors — Regenerate the access token and reconnect
Dataset ID not found — Verify you copied the correct Dataset or Pixel ID
No conversions exporting — Confirm fbclid capture and event name mapping

Verify Setup

Trigger a conversion event in Mixpanel
Check Vendo integration logs for a successful export
Confirm the conversion appears in Meta Ads Manager after processing time
