API Error with website integration

[Spatterson1]

I am new to Imap and not very technically savvy, so please work with me.

I used the HTML code provided to embed a google map made here on my website. It worked for a week, but now I am suddenly getting this error: "This page didn't load Google Maps correctly. See the JavaScript console for technical details."

Upon googling articles, etc. It appears that it is a google maps API error: MissingKeyMapError.

I obtained an API key from google maps, but do not know where to put it in the code or if I need to add something additional (remember I'm a novice)... please help... I need this up and working for a client.
