I am using Dialogflow's Messenger from https://cloud.google.com/dialogflow/docs/integrations/dialogflow-messenger, and was trying to find a way to pass some custom payload to be used during fulfillment. Through HTML customizations, it is possible to pass a user-id which will be passed to DialogFlow through the queryParams.payload field. Is there a way to pass more info other than user-id, through another way?
I was exploring the use of AJAX interceptors to intercept the body of the XHR request to Dialogflow, and am able to intercept the body as {"queryInput":{"event":{"name":"WELCOME","languageCode":"en"}}}. I was wondering if it would be possible to add a custom payload and retrieve it through fulfillment, such as {"queryInput":{"event":{"name":"WELCOME","languageCode":"en"}},"queryParameters":{"payload":{"payloadkey":"payloadvalue"}}} to extract the custom payload.
Does anyone know a solution to this?

i have a Use Case where i need to receive image as input from user in dialogflow chatbot. This images is require to send in webhook request to rest end point as fulfillment.
I couldn't find anything which resembles to my requirement and also not sure whether it is supported in dialogflow or not.
Thanks in advance!
Dialogflow cannot take an image as input and map it to an intent directly. However, what you can do is process that image and send some text to dialogflow which will trigger specific intent and then proceed to perform the desired action.
You need to have a bridge between your user agent and Dialogflow, which will handle all the text/image request. It will do all the pre-processing and then call Dialogflow.
In this way, you need to send message to the messenger user using it's API's and call dialogflow using API/SDK as well.
Hope it helps.
Is it possible to create a Logic Apps custom action similar to the Request Response action? If so, can you please guide me how I would do this? The Request Response action is different from other actions as it doesn't call an API, but instead responds to the trigger.
I'd like to create a specific version of the Request Response action that forces a certain status code and response structure, so that people using the connector understand how to use it. The action is to be used in conjunction with a custom trigger, which is basically a webhook. The API that call the webhook requires the response to be in a specific format. Right now I can make it work with the Request Response action, but I need to make sure I return the correct JSON structure.
Update, try Azure Api-Management. Otherwise, I would validate that all values are present and if not I would reply which values are missing.
I want to trigger an intent/event in Dialogflow [from my webhook/server] and have Dialogflow send a request to my /webhook instead of just responding to the POST request that I made which triggered the event. Is that possible? I want to send the user a message based on their input in our web application, but the response types could vary greatly so I can't define the message and payload in the DF web panel.

Yes, Dialogflow can send information to a webhook - it refers to this as fulfillment.
Keep in mind that the JSON sent by Dialogflow will be in its format, not yours, and it expects a reply in its format as well. This reply will include the message to be sent back to the user (the response to the original POST request).
I’m coding a bot using PHP-BotMan for complexity reasons and using Dialogflow query api to extract and manipulate the informations from the response. I saw examples and hints from people here and on dialogflow forum suggesting using context or events, some of them mixing both. What is the better way to handle this?
The flow of the application is:
user messages bot
bot queries (text or/and #event?) dialogflow
internally process a reply or return dialogflow slotfilling* request
text response bot reply user with last reply or asking to fill slot
Also, how can I be sure that a slotfilling process is finished with “actionIncomplete” only having two values, NULL or TRUE? The dialogflow query response doesn’t show wich slotfilling parameters are required or not…
Thanks for the help!!
slotfilling is when dialogflow sends a text response requesting required parameters to finish an intent, adding those replied values to the context
I was trying something similar to your scenario, here are few points i found helpful:
When Slotfitting with webhook, i can't use the "Required" params field since i have to control the input parameters via webhook (query database to provide options). Which means actionIncomplete field is not useful anymore.
I personally prefer to use context as it can add/remove params which gives you more control.
Hence the dialog was designed to use webhook to check all required params before move on to next conversation flow. and pop quick replies menu to ease and restrict possible input from users.
HTH.
I'm trying out few examples in Api.ai console. I see there are examples where the agent responds by using the values that are extracted from the user query or from the context. But is there a way to display response that is formed using the output of the action performed?
For example -
User: Is my pizza order confirmed?
Action: check order status
Response: Yes, it's confirmed (or "No, it's not")
You will have to use some custom webhook to do this, either integrating with a 3rd party API or will a server side call of your own to a database- in this case the webhook would take the user's ID and query if their pizza is ready or not, and this would then be passed back to API.ai.
Here is an example using a 3rd party webhook to do what you are asking:
https://github.com/api-ai/apiai-weather-webhook-sample
Yes you can do this with webhooks.
Typically, you would save the status of the order in your db, then you could have an intent that would:
Understand the query of your user (Is my pizza order confirmed)
The intent would call your webhook
the webhook would return the status order.
Api.ai would then give the answer.
When you use webhooks you need to return the speech response, the displayText, optionally the data that your apps need, the contextOut and the source.
I guess you would also need to have implement some context in api.ai so that you could now who is asking about the satus of the order. You would then be able to use the sessionId
Matt is correct here. You must use a webhook. Unfortunately the documentation from API.AI is currently very poor. Here's a screenshot example of an incoming post request. My message function will return an object with a desired response. In this case, I am using a Telegram chat bot. If you are not using any messenger, you can drop the data key: value. FollowupEvent is also optional.
Node.JS code with Restify
On your API.AI intent, make sure to check off Webhook. If you end getting the text response 'Broken' here, then something went wrong and you should check your error codes.

And lastly, under the fulfillment tab, make sure to enable the webhook and point it at the right endpoint.
