we face a problem regarding opt out and maybe someone here can help us out:
We have a matomo running under analytics.domain.tdl (piwik_ignore is set with this domain) We have a website under domain.tdl (here we use straight forward js tracking with opt out iframe, everything is fine) We have a react webapp under demo.domain.tdl. Here we want to track certain infos in the server using https://www.npmjs.com/package/matomo-tracker
In this webapp we wan’t to respect the opt out of a user, but we can not read the opt out cookie, cause it`s domain is analytics.domain.tdl not *.domain.tdl. We have found no way to change this.
The question now is, what information/param must be sent with the tracking call from the webapp to make the opt out effective and NOT track any call from a client, which has the opt out cookie set?
Any ideas are very welcome!
TIA and best regards
