At Tealium this is called EventDirect and yes you can perform this task with Tealium Collect Pixel. You will be responsible for making sure you have a Server End Point to receive the data which is in JSON format.
All you have to do is add the tag and then when you configure the Tag in TiQ, enter your own Server instead of the Tealium datacloud.tealiumiq.com server.
Tealium has two products AudienceStream and DataAccess, which can accept the JSON object and either process it or store it for you. Please reach out to your Tealium Account Manager if you would like more information on purchasing either of these products. However, you can write your own server side code to injest the JSON network request sent from the browser. We do not currently have any code that we can share for you to run serverside.
