Maybe I don’t get it, but shouldn’t it be possible to update a contact also via call to …/mtc/event/ with parameters? I could call this URL with ID or email in parameters, but still the cookie has priority and creates a new anonymous contact - or ads to the current user in the cookie? Thanks! ---

Hi, Are you asking about javascript tracking? ---

Nope. Its by calling an URL direkt: ```auto https://mauticbaseurl/mtc/event?email=leaduser@theirdomain.dom&page_title=decision&tags=direkt ``` It already creates the page hit event and ads the tag. However - not mapped to the Mautic user, but a new anonymous user. ![image](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/7/7ff3bd81840f827e88c57fc00212fd383084fc67.png) Whats the use case? I want to send a mail within the campaign to a Mautic User to make a decision. I can easily create that URL for the button. But as long as I can’t map the call to a defined lead contact, its not working the way I thought it could 😉 (Workaround is to call a prefilled form in kiosk mode. I’d still prefer the initial idea, as it could then directly continue in the campaign, based on the Mautic User decision.) ---

I think the idea is to call the tracking gif which displays the image + reads the cookie and identifies the user. ---

The tracking.gif definitely uses the cookie and thus its not possible to link the parameters with the concerned contact. (I tried it with the tracking.gif too.) As far as I understand my research, the call to the …/mtc/event with parameters should work too. Just not sure, if the user should be selectable by email (or ID) via the parameter. Its not working. ---

The tracking.gif will update the person who opens the gif. Are you trying to update another person based on ID? Why not to make an API call? ---

Hi, because I looking for a low level solution, where a campaign sends a mail to e.g. a sales person for them to to a decision, which influences the campaign for a particular lead. Its not the first time this requirement comes up from my clients… It would be easy to generate this link within a simple button. If I work with the API just for this scenario, I need to have one more active component to be setup and maintained 😉 So did I missunderstand the Call to /mtc/event/ ? I was successful with “page\_hit” and “tags”. But not with matching the contact ID / email.
