Hi.
We’re currently working on an updated version of the eBook.
You’ll get free access to the eBook when it is released.
 
You can find the API key on the same menu we mention in the eBook, but you’ll need to scroll down until you see a small snippet of code. Inside that snippet, you can find some information about your projects, including the API key.
 
Let me know if you can find it, or if you need further help.
 
Regards,
Sara

Hi Sara,
sorry but I still can’t see the key. See attachment for what I see.

Find screenshot here for download.

It seems they completely changed that area now and you need to create an app first before getting access to the API key.
 
At the bottom of that page, click on the </> icon to create a web app.
 

1. Give a name to your app. For example “ESP IOT App”. Select Also set up Firebase Hosting. Click on Register App.
2. In the next section, a code snipet will show up. In the firebaseConfig variable, you can see the apiKey. Copy the API key. Then, click Next.
3. Click Next-
4. Continue to the Console

 
Now, you can see that on your project setting page, you have the firebaseConfig variable with the API key.
 
Let me know if you can get the API key.
 
Now, you don’t need to follow section 4) on page 128 because we already did it here.
 
Regards,
Sara
 
 

Hi Sara,
thanks a lot. I found the API-Key now. But I hope that the other firebase pages haven’t changed as this one.
