My problem is that I am trying to cache some values on dialogflow and perform a different action if the values exists.
Is there any way to check the existence of say session entity or entity or context or anything else and then perform different actions based on whether they exist or not. In one case the action needs to be a webhook fulfillment, in the other case it needs to be a text reply without any webhook

I would like to know if I could extract output context(one that is set using the dialogflow console) from the fulfillment request.
This is important for me to programmatically handle the query since same set of user utterance could trigger different event handlers depending upon the previous statement/conversation utterance of the user.
I found answer to my question to extract the context that one sets using the dialogflow console in Python is
We are implementing our customized chatbot using dialog flow. When user enters any text, our javascript code sends this text to our python server and the server interacts with google dialog flow and server gets complete response. I just have couple of questions as below.
When server gets the response from dialog flow, it will process the
response and sends some response to UI. Do we still need to have
fulfillment enabled as our server is getting response? Basically if
server is interacting with dialog flow and getting response, what is
the use of webhook?
Is there anyway to enforce the dialog flow intents require at least
one of entities? I went through Can I make Dialogflow intents require atleast one of the trained entities? which says to enable webhook fulfillment for that intent and if no entities were provided, re prompt the user for at least one of a list of entities. So in my case, if webhook is not needed, do I need to do it in the server once server receives response or is there anyway dialog flow will automatically enforce the condition with out server taking the responsibility?
In your case, no, you don't need to use webhook fulfillment.
You may still wish to use it, however, if you want to separate business logic (which would be in the webhook) from UI/UX logic (which would be in your python server and in the javascript client). But there is no requirement that you separate things this way.
Similarly, you can use your python code to enforce "at least one of" the parameters matching - you're moving that logic from the webhook into your existing server.
Either way, this is a bit kludgy. One alternative if you have different entity types is to have multiple Intents, one for each possible type, and to mark the parameter as required. This way the Intent will only match if the parameter is provided. If you then need to report each of these Intents as the "same" Intent, you can add that logic to your python code.
I am trying to enable implicit invocation ("deep links") for my actions which are based on DialogFlow conversational model.
I cannot figure out how to make implicit invocation recognize session entities.
For example, I have an intent which is triggered by the following training phrase:
What is the status of the panel <xxx>?
where <xxx> is mapped to a session entity.
Session entities are pushed to DialogFlow servers upon the first intent request (that is, when receiving the first webhook call for the conversation).
While the intent works well AFTER invoking the app via Ok Google, talk to <invocation words>, I cannot make THIS work:
Ok Google, talk to <invocation> and ask what is the status of the panel <xxx>
because when the intent webhook request is called, the session entity parameter is simply empty, since session entities get populated after DialogFlow matches the intent and calls the webhook.
Is there a way to have session entities pushed somewhere in between?
How do you manage to have deep links work with session entities?
I am trying to wrap my head around using Dialogflow for developing and integrating an SMS chatbot with our custom CRM. The creation of an Intent is pretty powerful and straight forward. However, I am trying to understand best practices for something. If I have an intent used to return the price of a service at a certain location, I can model that very easily within dialog flow. However, when an SMS message comes in, it will be from a new customer or a known existing customer for a certain location. For existing customers, we already know the location and therefore don't want them to have to specify the location value in the intent. Prior to sending the inbound SMS message to the client API to match the intent, how can I pre-set the "location" parameter value in the intent so it does exists even if that inbound SMS message did not include it? For example a known customer in Dallas would just have to say "how much is a xxx" instead of "how much is a xxx in Dallas".
Can you use the API to set a parameter value prior to calling the API to try and match the intent? If so, how do you get do that without a session ID? The reason the "location" is needed is because when we get to the fulfillment, the prices for the same service are different based on the location so I will need to be known but we don't want to make existing customers say the location.
Maybe another option is to have a Location intent with an event that we can trigger through the API. this would have an output context on it called location and fulfillment that sets the parameter value. But even then I struggle with understanding how to pass in values like location, phone number, etc into dialogflow from the calling application so dialogflow has those parameter values to use in fulfillment.
Reading documentation, watching videos and starting to test client API v2
This is certainly possible. What you would want to do is use the Dialogflow API for this. Here you can find the languages for which Google has created client libraries: https://cloud.google.com/dialogflow/docs/reference/libraries/overview
As soon as you have any 'if' in your code you should use the fulfillment: https://dialogflow.com/docs/fulfillment
How I would handle this:
Client sends SMS
You check in your back-end if this user is known. If known -> don't ask location, else you ask the location
Match the user query against the Dialogflow client library
Dialogflow will return the intent if (any) is matched
You should define and implement any logic before calling the Dialogflow library.
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.
