I used the supplied PHP tracking API wrapper library to do a bulk tracking event and I get the response:
{“status”:“success”,“tracked”:0,“invalid”:1375}
Interestingly it worked before, but it stopped working after doing a version upgrade and migrating to a different location. Need some guidance how to possibly troubleshoot that problem.
I did some tests with Postman and with debugging. Doing a single request tracking works perfectly. I take the same token and put it into a bulk tracking request and I get the error:
WARNING! token_auth = e5a057fc50c248349ba596aeeecd2798 is not valid, Super User / Admin / Write was NOT authenticated []
I raised an issue on Github and they confirmed a bug:
Seems there is no bugfix that far, and I continue to avoid bulk tracking. They say there is a token that allows GET parameters ( Secure use only = No ) that is supposed to be working. I did not try to investigate that, but I see when you create the token, you can deselect: Only allow secure requests. Try it out if that makes it work.
