Action
You define an action in Dialogflow ES intents to tell your webhook which branch of the custom business logic it should execute.

Contexts are used in Dialogflow ES to manage the state of the conversation as well as to guide the conversation along different paths even if the user says the same phrase. Dialogflow CX does not need/use contexts as it supports conversation state automatically There are two kinds of contexts in Dialogflow ES – input context…
Both Dialogflow ES and Dialogflow CX support entities and they also behave similarly. An entity represents a predefined categoy of objects and the basic idea is borrowed from the field of Natural Language Processing. Named entity recognition (NER)—also called entity chunking or entity extraction—is a component of natural language processing (NLP) that identifies predefined categories…
Events are used in both Dialogflow ES and Dialogflow CX as triggers – they trigger something like an intent or an intent transition route – which fire without any user utterance. The best example is the WELCOME event in ES which has a very specific role – it will automatically fire the intent which contains…
You can use follow up events in Dialogflow ES to trigger an intent from a webhook or from a REST API call. For example, it might be a good way to implement slot filling using webhooks. As you might imagine, this is a fairly complex feature and you need a programmer on your team to…
You can use follow up intents in Dialogflow ES to chain intents together in a conversation. I recommend that people avoid using follow up intents and instead define their own input and output contexts to simulate the behavior of follow up intents. This makes your bot more flexible and will also help you debug issues…
Both Dialogflow ES and Dialogflow CX have the concept of intents, but they don’t have the same behavior. An intent represents what the user wants. “Switch on the lights” “Order a pizza” etc. In the case of Dialogflow ES, the bot’s response is added into the intent itself. But in Dialogflow CX, an intent only…
Both ES and CX support the concept of parameters. If entities are the categories or types of proper nouns, parameters are the actual values. For example, “city” would be an entity type, and Dallas would be the parameter (entity value). Dialogflow ES and CX allow you to extract parameter values from a user utterance. For…
In Dialogflow ES you can set the default value of a parameter. This can be especially helpful in situations where you wish the assign some value to a parameter but the value is not extracted from user utterance. For example, you might build a Quiz Bot and want to assign a score of 1 or…
You can use the Simulator in both Dialogflow ES and Dialogflow CX to test your conversation without incurring any charges. Here is what the simulator looks like in Dialogflow ES: And this is what the Simulator looks like in Dialogflow CX: Given that Dialogflow CX is based on state machines, it provides a lot more…
An utterance is simply what the user says to the bot. Both ES and CX uses the phrase “training phrases” to specify user utterances. Here is what it looks like in ES:
You can use webhooks to add custom business logic in both Dialogflow ES and Dialogflow CX. You need to write some code running on a remote server to build webhooks, and the data sent to your webhook will be in a pre-specified format, and you need to ensure that the data returned from your webhook…
