Sorry, being a software engineer for 20 years, let me paste here strings so someone would not have to get it from a screenshot :slight_smile:

Hey @wizard_files3 ,

The API Key you used to generate the Web SDK signature is not the same API Key that you shared.

Double check you are using a JWT App API Key and Secret to generate the Web SDK signature. :slight_smile:
