This folio describes how you can create new apps that receive, process, and respond to events from Google Conversation:

  • Receive messages and other kinds of events generated by Google Chat
  • Send outcome responses and other letters into Google Chat

Endpoint types

Events from Google Chat are delivered to your app via an endpoint, of which there are different types:

  • HTTPS endpoints present your app as a web service. You'll demand to gear up a web server to apply as an interface for your app's implementation. Your app can answer synchronously or asynchronously to these events.
  • Google Cloud Pub/Sub endpoints apply a topic on Google Cloud Pub/Sub to relay an event to your app's implementation. This is useful when your implementation is behind a firewall. Apps that use pub/sub endpoints tin simply answer asynchronously.
  • DialogFlow endpoints allow your app utilize the natural language processing (NLP) capabilities of DialogFlow. Please encounter DialogFlow documentation for details.

For a uncomplicated, straightforward app architecture, try implementing a app using an HTTPS endpoint (a web service, essentially) that responds synchronously, always enclosing its payload in the HTTPS Post response. This approach does not involve authorization, so it doesn't demand a service business relationship. Come across the elementary app implementation section below for an example of this style of app.

You may need to take a more than complex approach if your app is backside a firewall or sends unsolicited messages such as alarms or other notifications to Google Chat.

tl;dr... A very uncomplicated app implementation

The following lawmaking implements a uncomplicated app in Python using the Flask web framework.

          #!/usr/bin/env python3 """Example app that returns a synchronous response."""  from flask import Flask, request, json   app = Flask(__name__)   @app.route('/', methods=['Post']) def on_event():   """Handles an outcome from Google Conversation."""   result = request.get_json()   if result['type'] == 'ADDED_TO_SPACE' and non event['space']['singleUserBotDm']:     text = 'Cheers for calculation me to "%south"!' % (consequence['space']['displayName'] if issue['space']['displayName'] else 'this chat')   elif consequence['type'] == 'MESSAGE':     text = 'Yous said: `%s`' % upshot['message']['text']   else:     return   return json.jsonify({'text': text})   if __name__ == '__main__':   app.run(port=8080, debug=True)

Because it's a web service, the app presents an HTTPS endpoint and doesn't demand to employ Cloud Pub/Sub to relay events to it. And because information technology always returns its response payload within the JSON response, it doesn't need to authenticate using a service business relationship.

Treatment events from Google Chat

This section describes how to receive and procedure events that your app receives from Google Chat.

Registering the app

Before your app can receive events from Google Conversation, you must specify its endpoint in the Chat API configuration tab when you publish your app.

In one case you've registered the endpoint and published your app, Google Chat volition recognize events addressed to your app and dispatch them to the specified endpoint.

Verifying app actuality

Once you've registered your HTTPS app, you demand a way for your implementation to verify that the request is actually coming from Google.

Google Conversation includes a bearer token in the Say-so header of every HTTPS Request to a app. For instance:

          Mail service Host: yourappurl.com Authority: Bearer AbCdEf123456 Content-Blazon: awarding/json User-Agent: Google-Dynamite

The string AbCdEf123456 in the example higher up is the bearer authority token. This is a cryptographic token produced past Google. You can verify your bearer token using an open source Google API customer library:

  • Java: https://github.com/google/google-api-java-client
  • Python: https://github.com/google/google-api-python-client
  • .NET: https://github.com/google/google-api-dotnet-client

All bearer tokens sent with requests from Google chat will have chat@organization.gserviceaccount.com as the issuee, with the audience field specifying the target app'south project number from the Google API Console. For example, if the request is for a app with the projection number 1234567890, then the audience is 1234567890.

You should verify that the request is coming from Google and is intended for the target app. If the token doesn't verify, the app should respond to the request with an HTTPS response code 401 (Unauthorized).

Java

              import java.io.IOException; import java.security.GeneralSecurityException; import java.util.Collections;  import com.google.api.client.googleapis.auth.oauth2.GoogleIdToken; import com.google.api.customer.googleapis.auth.oauth2.GoogleIdTokenVerifier; import com.google.api.client.googleapis.auth.oauth2.GooglePublicKeysManager; import com.google.api.client.http.apache.ApacheHttpTransport; import com.google.api.client.json.JsonFactory; import com.google.api.client.json.jackson.JacksonFactory;  /** Tool for verifying JWT Tokens for Apps in Google Chat. */ public class JWTVerify {   // Bearer Tokens received by apps will always specify this issuer.   static String CHAT_ISSUER = "chat@arrangement.gserviceaccount.com";    // Url to obtain the public document for the issuer.   static String PUBLIC_CERT_URL_PREFIX =       "https://www.googleapis.com/service_accounts/v1/metadata/x509/";    // Intended audience of the token, which volition be the projection number of the app.   static String AUDIENCE = "1234567890";    // Become this value from the request's Authorisation HTTPS header.   // For instance, for "Authorization: Bearer AbCdEf123456" use "AbCdEf123456"   static String BEARER_TOKEN = "AbCdEf123456";    public static void master(String[] args) throws GeneralSecurityException, IOException {     JsonFactory factory = new JacksonFactory();      GooglePublicKeysManager.Architect keyManagerBuilder =         new GooglePublicKeysManager.Architect(new ApacheHttpTransport(), factory);      Cord certUrl = PUBLIC_CERT_URL_PREFIX + CHAT_ISSUER;     keyManagerBuilder.setPublicCertsEncodedUrl(certUrl);      GoogleIdTokenVerifier.Architect verifierBuilder =         new GoogleIdTokenVerifier.Builder(keyManagerBuilder.build());     verifierBuilder.setIssuer(CHAT_ISSUER);     GoogleIdTokenVerifier verifier = verifierBuilder.build();      GoogleIdToken idToken = GoogleIdToken.parse(mill, BEARER_TOKEN);     if (idToken == null) {       System.out.println("Token cannot be parsed");       Organisation.go out(-1);     }      // Verify valid token, signed by CHAT_ISSUER.     if (!verifier.verify(idToken)         || !idToken.verifyAudience(Collections.singletonList(Audience))         || !idToken.verifyIssuer(CHAT_ISSUER)) {       System.out.println("Invalid token");       System.leave(-one);     }      // Token originates from Google and is targeted to a specific client.     Arrangement.out.println("The token is valid");   } }

Python

              import sys  from oauth2client import client  # Bearer Tokens received by apps will always specify this issuer. CHAT_ISSUER = 'chat@system.gserviceaccount.com'  # Url to obtain the public certificate for the issuer. PUBLIC_CERT_URL_PREFIX = 'https://world wide web.googleapis.com/service_accounts/v1/metadata/x509/'  # Intended audition of the token, which will be the projection number of the app. Audition = '1234567890'  # Get this value from the request's Potency HTTPS header. # For case, for 'Authorization: Bearer AbCdEf123456' employ 'AbCdEf123456'. BEARER_TOKEN = 'AbCdEf123456'  effort:   # Verify valid token, signed by CHAT_ISSUER, intended for a third party.   token = customer.verify_id_token(       BEARER_TOKEN, AUDIENCE, cert_uri=PUBLIC_CERT_URL_PREFIX + CHAT_ISSUER)    if token['iss'] != CHAT_ISSUER:     sys.exit('Invalid issuee') except:   sys.exit('Invalid token')  # Token originates from Google and is targeted to a specific client. print 'The token is valid'

Event payload

When your app receives an event from Google Chat, the effect includes a request body: this is the JSON payload that represents the event. The request torso always includes the following data:

  • type: A string that specifies the type of the outcome.
  • eventTime: A string containing the event timestamp.

Additional information contained in the request body depends on the outcome type. The post-obit example shows a possible payload:

          {   "blazon": "Message",   "eventTime": "2017-03-02T19:02:59.910959Z",   "space": {     "proper noun": "spaces/AAAAAAAAAAA",     "displayName": "All-time Dogs Give-and-take Infinite",     "type": "ROOM"   },   "message": {     "name": "spaces/AAAAAAAAAAA/messages/CCCCCCCCCCC",     "sender": {       "name": "users/12345678901234567890",       "displayName": "Chris Corgi",       "avatarUrl": "https://lh3.googleusercontent.com/.../photo.jpg",       "email": "chriscorgi@example.com"     },     "createTime": "2017-03-02T19:02:59.910959Z",     "text": "I mean is there any practiced reason their legs should be longer?",     "thread": {       "name": "spaces/AAAAAAAAAAA/threads/BBBBBBBBBBB"     }   } }

Run into the event formats reference for details of the different event types and their asking formats.

Processing the event

When your app receives an outcome from Google Chat, what information technology does with that outcome is completely implementation dependent. The app may look up some information from a data source, tape the result information, or merely about anything else. This processing behavior is essentially what defines the app.

In virtually cases, an app will not only process the information contained in the event, just will generate a response back to the thread that issued the effect. The following diagram describes a typical interaction with an app in a Chat space:

There are 3 kinds of events shown in the above diagram: ADDED_TO_SPACE, Bulletin, and REMOVED_FROM_SPACE. An app can't respond after being removed from a space, only it can answer to the other 2 types.

Responding synchronously

An app can respond to an event synchronously by returning a JSON-formatted message payload in the HTTPS response. The deadline for a synchronous response is 30 seconds.

A synchronous response from an app is e'er posted in the thread that generated the event to the app.

Responding asynchronously

If an app needs to reply to a user bulletin beyond the xxx-second deadline (for example, it may demand to report back subsequently completing a long-running chore), it tin can respond asynchronously. This is exactly like sending a spontaneous message equally described in the into an existing thread department.

Lightweight apps that don't apply service accounts cannot respond asynchronously.

Retry

If an HTTPS request to your app fails (e.g. timeout, temporary network failure, or a non-2xx HTTPS status lawmaking), Google Chat will additionally retry delivery twice, with at to the lowest degree a 10-second delay between each retry. Equally a result, an app may receive the same message upwardly to three times in certain situations. No retry is attempted if the asking completes successfully but returns an invalid bulletin payload.

App-initiated messages

This section describes how apps can ship arbitrary messages into a space.

Many apps send messages only in direct response to an effect that they receive from Google Chat. All the same, some apps might send messages when triggered by other things, for example:

  • A fourth dimension-based warning like a agenda upshot
  • A modify in state of some relevant information
  • The completion of a remote procedure

This department describes how to transport these messages from your app to Google Chat.

Into an existing thread

To send a message every bit a respond in an existing thread, specify the thread's ID in the message payload every bit shown below:

{   "text": "...",   "thread": {      "name": "spaces/SPACE_ID/threads/THREAD_ID"   } }

The specific THREAD_ID is available in the payload of Message events that your app receives from Google Chat. Keep track of this ID so that the app can inject messages into the thread.

As a new thread

To ship a message into Google Chat as a new thread, your app should omit the thread ID, as shown below:

https://chat.googleapis.com/v1/spaces/SPACE_ID/messages

Requests must specify Content-Type: application/json in the request header. See the Google Chat API Message Format reference for the JSON format of Google Chat messages. The following case shows a simple request using cURL:

          curl -10 Post \     -H 'Content-Type: application/json' \     'https://chat.googleapis.com/....' \     -d '{"text": "Hello!"}'

Thread key

In many cases, apps may want to mail service multiple messages related to the same entity into the aforementioned thread. For example, a bug tracker integration may want to post all notification messages related to the same bug into the same thread.

To attain this, apps can specify an arbitrary thread key in each request. Messages posted with the aforementioned thread key volition be grouped into the aforementioned thread. For example, the example bug tracker integration above might utilise the bug ID equally office of a consistent thread key. The first notification message for a bug will and then create a new thread; all subsequent messages for the aforementioned bug will be posted into that same thread.

The thread cardinal is specified in the threadKey query parameter in an entering HTTPS request. For instance:

https://chat.googleapis.com/v1/spaces/SPACE_ID/letters?\     threadKey=ARBITRARY_STRING

Thread keys are also scoped to a specific app; if 2 different apps happen to both post messages using the same thread primal, those two messages will non be grouped into the same thread.
