Add Block
In your Gutenberg editor, find the Business Reviews Block and insert it, just like others block.


Requirements
After adding the block, you will see the requirement for Authorization or Access Token.
- To show Google Place Reviews, you have to enter Google Place API Key and Google Place ID.
- To show Yelp Reviews, you have to enter Yelp API Key and Yelp Business URL.
- To show the Facebook Page Reviews, you have to Login with Facebook and access the Page.
Don’t worry you don’t need to put all the authorizations at a time. If you want to show Google Place Reviews you just have to add Google Place API Key and Google Place ID. If you want to show Yelp Business Reviews you just have to add Yelp API Key and Yelp Business URL. Or if you want to show Facebook Page Reviews you just have to authorize the Facebook Page.
Insert the authorization keys in Editor Header Settings. After inserting the keys you must have to click on Save Information to save the info.

After, adding the authorization keys, you will see the reviews are showing.
