How does Unleash parse UserId?

[Thomas-Rice]

Hi,
I have a general question. I'm looking at using unleash & was wondering how userIds are interpreted? Does unleash look at headers / cookies etc or are userIds passed in another way?

Hey @Thomas-Rice!

So it depends a little on what you mean by that. It sounds like you're asking about how the SDKs handle userIds (please shout if I'm wrong about that!).

It depends on which type of SDK you're using, for the server side SDKs, the userId is passed into the SDK itself as part of the Context, in that case, the userId never leaves your servers, everything is evaluated locally.

For the Client Side SDKs, they're also part of the context property, but that context is destructed into a set of URL parameters, you see see a sample in action here. So, effectively userId is passed as a URL param.

Did that answer your question?

Hi @sighphyre
Thank you very much for the information!
I believe I understand, it's passing in UserIDs via parameters/values via url/json :)

Nothing but a pleasure, happy Unleashing
