Hello Fellow makers , really need your help here I’m having an issue with google cloud visions, this is your basic whatsapp scenario and it says there is an issue with my API but on google my API is working and billing is enabled , please help am i maybe pasting the wrong key … its been 2 hours

Hi there,

For the “API key not valid” issue, it appears that you are using a Server key, but you need to use a browser key.
The Vision API Getting Started page has detailed screenshots.

Can you please refer and see if you managed to get it through?
