Google Drive API

Setting up your Credentials

For "What data will you be accessing?", enter "User Data".

5. Click on "What credentials do I need?"

6. For "Authorized JavaScript origins:", enter the name of your server, i.e "https://www.nsbasic.com"

7. Click on Create client ID

8. On Credentials screen, select Create credentials.

9. Choose API Key

10. Choose Browser key

11. Create. Note: It may take up to 5 minutes for settings to take effect

12. Your credentials screen should now look like this: File:Credentials

13. Copy credentials: Client ID. It will look something like this: 304468290387-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com Copy this into the CLIENT_ID variable in your Google Drive App.

14. Copy API key. It will look something like this: AIzxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Copy this into the API_KEY variable in your Google Drive App.

Getting the list of files on your Google Drive

1. Click on "List Files". The files on your Google Drive will appear, along with their File IDs.

2. Get the FILE_ID for your spreadsheet from the File_Id column. Put that in the top of the app: it is hardcoded in the sample. You're welcome to use better ways to select the FILE_ID in your own app.

Reading and Writing Spreadsheets

1. Restart the app and click on Get Spreadsheet. The contents of the spreadsheet will appear.

2. You can now modify the spreadsheet in your code.
