Meta rejects the Conversions API token

Reviewed on 5 October 2026
On this page

If the Conversions API shows Token rejected and you got a notice, Meta no longer accepts the purchases OnBio sends it from the server. Find the cause here and follow its steps.

The token expired or was revoked

How to recognise it

The status of Meta Conversions API says Token rejected. It happens when the token was generated with an expiry or when someone removed it in Meta's Events Manager.

Where to check it

You see it in Pixels, in the status of the Conversions API.

What to do
  1. 1. Generate a new token in Meta's Events Manager, in your pixel's settings.
  2. 2. Click Change token and paste the new one in Access token.
  3. 3. Click Turn on the Conversions API.

The token belongs to another pixel

How to recognise it

The token is valid, but you generated it for a pixel other than the one you saved in Meta pixel. Meta rejects the sends because they do not match.

Where to check it

You see it in Pixels, comparing the Meta pixel with the one in the Events Manager.

What to do

Generate the token from the same pixel you have saved in OnBio, or change the Meta pixel to the right one and click Save. Then paste the token with Change token and turn the API on.

You lost access to the pixel

How to recognise it

The Meta account that generated the token no longer has permission over the pixel, for example because it left your business account. The status says Token rejected even if the token is recent.

Where to check it

You see it in Pixels, and in Meta, in the pixel's permissions.

What to do

Ask in your Meta business account for admin access to the pixel, generate a new token with that account and paste it with Change token.

Frequently asked questions

Are purchases lost while the token is rejected?

The browser pixel keeps sending the purchases of those who accepted advertising. Only the server ones stop arriving, the ones that recover sales a blocker hides. Those that failed with the rejected token are not resent, so put in the new token as soon as you can.
