I would like to know if there is a way using DialogFlow CX to get the chatbot to send a follow up message after a certain x period of time when a customer doesn't respond.
ie: Customer reaches out, chatbot responses, after 2 minutes, the chatbot will send a message like are you still there? message or something like that.
Thanks!
I dont know how to set this up if its possible.
In many ways, it depends on exactly what integration you're using and what that integration supports. While there is some support for this in Dialogflow CX, it probably isn't as automatic as you want.
If you're building using one of the telephony integrations, there are some agent settings that let you set the "No speech timeout" period. At the end of this period (5 seconds by default), if the caller hasn't said anything, then a no-input event will be triggered and you can use this to repeat the message, prompt if they're still there, or take other actions that may be contextually appropriate.
If you are using a text agent, there isn't any such timeout built in. However, if you can keep track of this on the client side (ie - in whatever is sending the messages to Dialogflow), then you can determine if there has been no input for the predetermined amount of time and send an event to Dialogflow that will trigger the reprompt.
For example, if you're using Dialogflow Messenger, you could setup a JavaScript event that sets a timeout when it gets a response from Dialogflow and clears it when the user sends a request. If it ever times out, it could bring up a message re-prompting the user.

I am using an exteranl API that do some work for 15min, when it finish it will call any URL you define in your initial request to send the results to.
Is it possible for dialogFlow to accept this result in 15min? Is there like a built-in async response handler in DialogFlow?
If you are calling external APIs via webhook, it would be subject to the maximum webhook timeout limit of 30 seconds. After the response timeout is exceeded, Dialogflow invokes a webhook error or timeout built-in event and continues processing as usual. Therefore, Dialogflow would no longer accept webhook responses more than the set timeout limit.
Note that conversational interfaces are meant to be designed as a continuous message exchange between the end user and the app/bot. If your web service requires more time for executing operations in the background and this cannot be optimized, consider redesigning the conversation flow in such a way that end users don't wait for the app/bot to reply for more than the set webhook timeout limit.
If you have your own custom application (integrated using APIs or Client Libraries), you can instead call/invoke the function that needs 15 minutes of work (let’s call this function_1) from your custom application.
Here’s a basic setup:
User enters a query from the interface of your custom application.
Your custom application sends the user query with the Detect Intent
request to the Dialogflow agent (using APIs or Client Libraries).
After your custom application receives a Detect Intent response from
the agent, you can create code to get the intent name or event name
from the detectIntentResponse.queryResult.match.intent.displayName
or match.event response json respectively and then call/invoke
function_1 based on the intent or event matched.
Once function_1 is finished processing, you can either send a direct response to the
user in your custom application’s interface or send a Detect Intent
request to your agent so it matches an Intent and sends the intent
response back to your custom application.
No, it won't be possible as you describe it. The only way to call external services is through webhooks, but these are thought as calls that return a very specific object which Dialogflow then returns as an answer to the user directly, so they are inherently synchronous.
What you could do instead is think of a workaround. I don't know the specific of what service you're calling, but you could set up a small server to handle the webhook response from dialogflow which doesn't do anything except trigger the call to the external api, and when you get the answer you could process it (put the relevant content inside a "fulfilment" object as per Dialogflow specification) and trigger an event in your agent through the dialogflow API.
so the final process could look something like this.
user asks for e.g. "pizza": the right intent is triggered and the route for that intent calls a webhook server
your webhook server receives the call from dialogflow and calls the external api asking for the list of all pizzas ever created. it returns an empty fulfilment to the server
when the webhook server receives the response after 15 mins it triggers an event in the agent (look into the dialogflow api for your programming language of choice: python, node, java) and injects some parameters in the request, which you can then use to form a sentence in the agent
when I was just starting out I found this very useful to get a grasp of what the platform expects you to do in terms of interacting with external services, take a look at the graph especially which I think makes it clearer
Whenever my app posts ephemeral message to Slack channel (in response to a query by a user), I am unable to get the timestamp of my Slack app response. As I want to delete it once the user has made a selection using one of the buttons. Although I have subscribed to 'message.channels' event, I don't get a notification to my app whenever my app posts in the channel (in response to the user input), therefore, I am unable to get the timestamp of the message which I'll use to delete it. All I want is the timestamp of the message posted by my app so that I can delete it but I am unable to receive the timestamp. Please help!
For e.g. in Giphy app for Slack. Let's say the user invokes the app by calling '/giphy [dog]' where 'dog' is just an example of a search term. The app responds by sending a gif and user can either send it, shuffle to the next one or cancel it. I want a similar capability of cancelling the app response but I need the timestamp of the message in order to do so therefore I am asking for help.
Thanks.
Your approach can not work, because Slack is handling ephemeral messages differently from "normal" messages. They are only visible by one user and can not be modified by API methods (e.g. deletion).
But of course its possible to replace ephemeral messages. Here is how:
Your app can just reply to the interactive message request from Slack with a new message. That new message will by default override the original message including ephemeral messages.
You can reply in two ways:
Directly reply to the request from Slack with a message within 3 seconds
Send a message to the response_url from the Slack request within 30 minutes.
See here for the official documentation on how to respond to interactive messages.
This approach works both with interactive messages and slash commands.

If I make a request to the gmail API for Users.messages.list it will return 100 of the newest messages.
If I make another request, 1 minute later and there are no new emails it will return the same 100 most recent messages.
If I make a third request, 2 minutes after the original and there is a reply to one of the 100 most recent messages it will still return the 100 most recent messages.
The problem with this is the it only returns the message id and thread id, not if there is a new reply or not. That would mean that I would have to check every message that I have locally stored, or every one of the 100 returned messages just to know if there was a reply to it or not.
The way that works, you couldn't "check" your email via the api because if you had stored 10000 messages and you were checking replies on all of them you would use up your entire API "number of requests" allocation in a single day!
What's wrong with you Google?
Sure I could use pop3 or imap but why when I could just use something like /list_recent?
You should definitely take a look at this part of the Gmail API documentation: https://developers.google.com/gmail/api/guides/push
Basically, it explains you how you can setup a "watch" over a Gmail account and receive notifications (new e-mail, deleted e-mail, labels added...) through Pub/Sub, the messaging queue protocol from Google.
The notifications will contain an historyId, which is a kind of milestone in the Gmail account. Using the /history endpoint, you'll then get the e-mails that were added and/or deleted since this history point. You have to store the latest historyId you handled somewhere in your app, so that you can query the right changes (and not miss anything) on the next notification.
If you don't need to react to changes in real-time, maybe you can call the /history endpoint periodically, but it will definitely be less efficient at scale.
It takes a bit of work to get this working but at the end of the day you get a very efficient system able to react about changes in real-time.
On facebook Chatbot or others platform we can send message directly to the user.
So for one question we can send multiple answer.
Now, that i'm developing for Google Home, I need to do the same.
I didn't find this opttion.
Dialogflow HTTP call to my server is the only output available.
So is there anything i missed to send message back to user in case I have a multiple messages answer?
(Or do I have to bufferise very message my hook creates before sending it back?)
Thanks
The conversation model for the Google Assistant is different - you can only send a message to the user in response to the user sending you a message. You can only send a single response, but it may have multiple parts (up to two Simple responses, containing messages, plus other features such as cards and carousels).
If you need to send multiple things back - you may need to rethink how you're doing it or how much you're sending back at a time. The Assistant is primarily for audible responses, and a long audible response is generally not a good UX.
Hey in my team's slack (messaging system for those who don't know) we have an automatic response, so that when anyone says "trump", slackbot automatically responds with "the wall just got ten feet higher". Now I want to make a counter that essentially allows slackbot to state "the wall just got ten feet higher, wall height:(have a updated value according to number of times "trump" has been stated)" So basically I want a way to have a value that updates the wall height but I am lost on how to do that within slackbot. Any help is much appreciated, thanks to all!
The default features provided by Slackbot only allows it to respond to keywords, but not much more. So to provide that additional feature you would need to develop a custom bot.
For your use case I would recommend building a so called internal integration for Slack using the Events API.
Internal integration allows you to add custom functions for your Slack team only (as opposed to a full fledged Slack app, that could also be installed and used for other Slack teams).
The Events API allows you to set up a bot that listens to messages and can react to keywords like "trump".
An alternative approach to the events API would be the outgoing webhook. However this function is now deprecated and should no longer be used. Also it only works with public channels.
To set this up you will need to develop a small webservice (e.g. in PHP) that listens on a webserver for requests from the events API, keeps count of how many times the keyword has been invoked in the past and sends an appropriate message back to your Slack team every time the keyword is used.
I can recommend reading the excellent official Slack API documentation if you want to learn more.
If you are familiar with PHP this can be done easily using the Slackbot Framework. It supports Events API allowing you to listen to messages in channels or direct messages (depending on the permission scopes of your APP). So all the conversations on Slack can be sent to your server and you can search for the specific keyword in every message. Then send back an appropriate message to Slack. In summary, the first step is to create an APP for your slack team at https://api.slack.com/apps?new_app=1. Next step is to install the Slackbot Framework which is explained here. Hope this is helpful.
That can also be done by integrating custom slack bot using Django. You'll have to subscribe events and based on events, Slack will send conversation message to the given url, and based on the event, you can write your logic to increase count and post message back to slack work space.
