When using the HTTP Events API ([https://developers.hubspot.com/docs/methods/enterprise\_events/http\_api](https://developers.hubspot.com/docs/methods/enterprise_events/http_api)), it looks like it’s possible to specify an email which attaches the event to a contact. Is it possible to do this with the JavaScript Events API ([https://developers.hubspot.com/docs/methods/tracking\_code\_api/javascript\_events\_api](https://developers.hubspot.com/docs/methods/tracking_code_api/javascript_events_api))?

I tried doing the following, but it didn’t work.

```auto
 _hsq.push(["trackEvent", {
 id: "User has visited your website",
 value: 0,
 email: 'drichied@njmonthly.com'
 }]);

```

Hi [@dwebrich](https://community.hubspot.com/u/dwebrich),

When paired with the [Identify a visitor](https://developers.hubspot.com/docs/methods/tracking_code_api/identify_visitor) method, the [JavaScript event](https://developers.hubspot.com/docs/methods/tracking_code_api/javascript_events_api) you create can be associated with a contact via email.

For example:

```auto
 function getParameterByName(name) {
 var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
 return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
 }

 var _hsq = window._hsq = window._hsq || [];
 _hsq.push(["identify",{
 email: getParameterByName("email")
 }]);
 _hsq.push(["trackEvent", {
 id: "User has visited your website",
 value: 0
 }]);

```

@IsaacTakushi

Is there generic API version or in python for sending events to Hubspot ?

Thanks,

Hi, @sanjaydojo.

There is an [HTTP Events API](https://developers.hubspot.com/docs/methods/enterprise_events/http_api). Is that what you’re looking for?

Hi @IsaacTakushi ,

Thank you for your great help.

Is it possible to associate it with the property other than email?

Thanks,

Sanjay

Hey, @sanjaydojo.

You can pass other contact property values by appending `&{property}={value}` to the request URL, but you do need `email` to identify the contact.

Per the documentation, you can use an external ID in the `id` parameter, but you will need an email value in at least one call to associate this external ID with a contact. Once that happens, you can use only the `id` value going forward.

Hi @IsaacTakushi,

Thank you again for your great help.

Is there a way of preventing the pixel on Website from sending custom events to Hubspot?

Thanks,

Sanjay

Hi, @sanjaydojo.

It’s not possible to stop event details from being passed to HubSpot after [this method](https://developers.hubspot.com/docs/methods/tracking_code_api/javascript_events_api) is called, so you’ll have to implement JavaScript logic around the `trackEvent` function to only fire it when you want it.
