GoogleApp
Use this lib to connect BJS with Google App Script​
Getting started
1. Go to https://script.google.com and create new project by button:
2. Paste the script from above into the script code editor and hit Save.
3.  From the Publish menu, select Deploy as web app…

4. Choose to execute the app as yourself, and allow Anyone, even anonymous to execute the script. (Note, depending on your Google Apps instance, this option may not be available. You will need to contact your Google Apps administrator, or else use a Gmail account.) Now click Deploy. You may be asked to review permissions now. Project version - always "New".
5. The URL that you get will be the webhook that you need use in this Lib. You can test this webhook in your browser first by pasting it. Note that depending on your Google Apps instance, you may need to adjust the URL to make it work. 
6. Install GoogleAppLib and WebhooksLib to bot
7. Create setup command:
/setup
1
// replace with your URL, obtained in step 4
2
Libs.GoogleApp.setUrl("https://script.google.com/macros/*******");

GACode - it is isolated function with Google App code. It can not have BJS code like Bot.sendMessage and etc. Only GA code!
But you can use variables and pass data with options for Bot.run method.
1
let myVar;
2
​
3
function GACode(){
4
   // Google App Script code here
5
   // Please note: this function is runs on GA not BB
6
   // ...
7
   
8
   myVar = 5; // Error! myVar is not defined in GA only in BB side
9
   
10
   // this will be works:
11
   let myVar;
12
   myVar = 5;
13
   
14
   Bot.sendMessage("ok")  // Error! It is BJS not GA code!
15
   
16
   let botName = bot.name; // Will be worked
17
   let myData = options.myData; // Will be worked if you pass 
18
   // options.myData with Bot.run(
19
   //    { command: "/thisCmd", options: { myData: "test" } })

Permissions
You need set permissions for Google App Script
Run Libs.GoogleAppLib.runin first time. You can have like such error:
Error on Google App script: "Exception"
"The script does not have permission to perform that action. Required permissions: (https://www.googleapis.com/auth/calendar || https://www.googleapis.com/auth/calendar.readonly || https://www.google.com/calendar/feeds)"
If you have such error you need set access rights.
Granting access rights via manifest file
Full help available here. From that help:
You can explicitly set the scopes your script project uses by editing its manifest file. The manifest field oauthScopes is an array of all scopes used by the project. To set your project's scopes, do the following:
1.Open the script project (script from step 2) in the Apps Script editor.
2.In the menu, select File > Project properties.
3.Select the Scopes tab.
4.Review the scopes your script currently requires and determine what changes need to be made. Click Cancel when finished.
5.If the manifest file appsscript.json isn't visible in the left nav bar, select the View > Show manifest file menu item.
6.Select the appsscript.json file in the left nav to open it.
7.Locate the top-level field labeled oauthScopes. If it is not present, you can add it.
8.The oauthScopes field specifies an array of strings. To set the scopes your project uses, replace the contents of this array with the scopes you want it to use. For example:
1
{
2
  "timeZone": "Asia/Tokyo",
3
  "dependencies": {
4
  },
5
  "webapp": {
6
    "access": "ANYONE_ANONYMOUS",
7
    "executeAs": "USER_DEPLOYING"
8
  },
9
  "exceptionLogging": "STACKDRIVER",
10
  "oauthScopes": ["https://www.googleapis.com/auth/script.send_mail",
11
                  "https://www.googleapis.com/auth/script.external_request",
12
                  "https://www.googleapis.com/auth/spreadsheets"],
13
  "runtimeVersion": "V8"
14
}
Copied!
9.​https://www.googleapis.com/auth/script.send_mail", "https://www.googleapis.com/auth/script.external_request - is mandatory scope
10.Save the manifest file using Ctrl+S or the Save file icon in the menu bar.
11.Publish your app again (see step 3)
​
Debugging
