Steps to generate your CAPI token

1

Sign in to Meta Events Manager

Sign in to Meta Events Manager at business.facebook.com/events_manager.
2

Find or create your pixel

If you already have a pixel, you’ll see it listed in the Data Sources panel — proceed to the next step.If you need to create one:
  • Click the green Connect Data Sources button
  • Select Web
  • Click Next or Get Started
  • Follow the instructions to create a new Meta Pixel
3

Open the pixel overview

In the Data Sources list, click your pixel’s name. You’ll land on the pixel’s Overview page.
4

Navigate to the Settings tab

On the pixel Overview page, click the Settings tab in the left-hand menu.
5

Generate the access token

On the Settings tab, scroll down to the Conversions API section and click Generate access token.
6

Copy your CAPI token

Copy the value of the access token shown in the dialog. This is your CAPI token.
The token is shown only once — copy it immediately to a secure location. If you close the dialog without copying, you’ll need to generate a new one.
Token format: starts with EAA, approximately 190 characters long (e.g., EAAxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx...).
7

Add the token to Upstack Data

Sign in to Upstack Data at app.upstackdata.com and open your Meta destination under Event Destinations. Paste the token into the Conversions API token field.
Make sure the Check to enable sending events via Facebook Conversions API checkbox is selected.
The CAPI token is sensitive — store it securely. The token is tied to a single Meta ad account and cannot be reused across accounts.
8

Verify the destination is healthy

In the Upstack dashboard, the Meta destination card should show Healthy with a green status indicator within 5 minutes.If the status shows Unhealthy:
  • Confirm the token starts with EAA and was pasted in full (no truncation, no whitespace).
  • Confirm the Conversions API checkbox is selected.
  • Confirm the Pixel ID matches the pixel you generated the token for.
