Hey @tommy

My question is How Long is the tk parameter valid?

WebSDK no tk length limitation , the limitation is the url max length.

Thanks @tommy!

Please could someone update the documentation to show the latest SDK version, otherwise new developers will be using an outdated SDK :slight_smile:
