We need case law to settle the matter but in general, the GDPR indicates that if you don't need to collect the data in order to perform the requested activity, you need explicit consent for collecting it, and will be held to a high standard in court if this every comes in to question.

Yes, but like the "cookie law" before it, it's absolutely fine to go ahead and do it if it's required (in the case of something like logging aggregate usage counts of APIs, that's easy to justify as a requirement for maintaining a reliable service; it's basic server monitoring).

Things like online stores using cookies to track a user's shopping cart across requests are completely fine, yet it seems like legal departments decided to be overly cautious and treat all cookies as potentially infringing. GDPR may be triggering similar reactions.

I wouldn't have a problem with that if marketing departments became equally cautious, but they seem to just slap on a banner and carry on as before :(

It's about data that can identify a user, not any data. A collection of actions with anonymized user IDs will not allow to identify the user (in most cases), so it's fine to keep it.

Very good to know.

Correct me if I'm wrong - seems like anonymizing the usage data complies with the GDPR, and thus the grandparent post still stands.

As long as you anonymise in a way that you can't de-anonymise it should be OK.

>>it seems/should

GDPR, I'm hoping that I don't have to bother my users with a "do you consent to" popup when the only thing I want to do is to log server-side the API calls so that I can see patterns in usage and such. If I were to show such a "do you consent to" popup users might mistakenly think I'm one of those techcrunchers with hundreds of data partners that all get to see your PII. I do not want to affiliate myself with those type of actors.

Anonymously of course. Should be fine, yeah?

Recital 26:

"The principles of data protection should therefore not apply to anonymous information, namely information which does not relate to an identified or identifiable natural person or to personal data rendered anonymous in such a manner that the data subject is not or no longer identifiable. This Regulation does not therefore concern the processing of such anonymous information, including for statistical or research purposes."

As long as it's not linked to a particular profile ("pseudonymous" doesn't count, it could still be linked), it's fine.
