Hi,

I try to track custom events. But I’ve got error messages in dataLayer during validation test.

_“The method ‘generate\_lead’ was not found in “\_paq” variable. Please have a look at the Piwik tracker documentation”_

_“The method ‘job\_offer’ was not found in “\_paq” variable. Please have a look at the Piwik tracker documentation”_

I think I used the right framework in Google Tag Manager. I also tried with Piwik Tag Manager.

Is there something I’m missing?

Have a great day,  
Olivier

Hi @olive,

Syntax for the custom event method is a bit different:

> **[API](https://developers.piwik.pro/en/latest/data_collection/web/javascript_tracking_client/api.html#trackEvent)**
>
> The following API allows the user to: track page views, track visits on multiple domains and subdomains, track e-commerce events (successful orders, cart changes, product and category views), track...

It should look something like this:  
`_paq.push(["trackEvent", "generate_lead", "Lead", "domaine"]);`

Hi Anthony,

Thanks! It seems better.

It should be like this, right?

Looks good. You can always use the tracker debugger to see whether any of the tracked events are being processed correctly.
