One of my training course students asked me this question about their Dialogflow Messenger bot: Your videos and courses helped me a lot to understand dialogflow. To finish my project i’m facing a specific issue, to return a dynamic hyperlink through fullfilment or webhook. First of all, I don’t recommend using the fulfillment library for…
In my webhook tutorials, I usually directly construct the JSON and send it back to Dialogflow. Obviously, this has the major benefit of explaining what happens under the hood, as someone pointed out on my YouTube channel: THANKS THANKS THANKS! For days i have been trying to find a video where people show how to…
In this tutorial I will explain how you can debug your Python Flask webhook for your Dialogflow bot using ngrok. I use the PyCharm professional IDE (you can also download the free PyCharm community edition) in this tutorial. 1 Create a new Pure Python project You can just start with a regular old Python project….
One of the things that I have mentioned before is that you need to have a programmer on your team if you would like to build a non-trivial Dialogflow bot. At the same time, all Dialogflow bot makers would still benefit from understanding the basics of webhooks. This tutorial will be helpful if you are…
This tutorial was a series of posts which was first published in October 2017. There have been many updates in Google Cloud after this tutorial was first created, so it may not be the best learning resource for this topic. A couple of things to note: almost certainly, the interface will look different today and…
I got a question recently on this topic. Now this isn’t an actual answer to this specific question. Rather, I will explain the approach you should use to handle these kinds of messages in general. At the same time, I think the general answer is becoming more important now because of an important reason. Static…
Some time back, I put up a survey on my website asking readers what they find most challenging about learning Dialogflow. The most challenging topic, not too surprisingly, was webhooks a.k.a fulfillment. This prompted me to write an article about why it is so hard to find good documentation for Dialogflow webhooks. And unfortunately it…
Are you tired of Dialogflow fulfillment tutorials which seem to be out of date by the time you read them? What if I said there is a way to understand how Dialogflow fulfillment works without using code? Since there is no code, there is very little chance for this approach to become obsolete. Use a…
Wondering which language to use for your Dialogflow webhook? In this article, I discuss some things you need to consider before choosing it. 1 NodeJS is asynchronous While NodeJS is clearly exploding in popularity, if you are not already proficient in NodeJS, you might want to use it to build a toy project first before…
I got this question in a comment recently: I have been asked this question a few times, so this might be a good opportunity to clarify. The inline editor uses Firebase cloud functions The code editor inside the Dialogflow console, also called as the Inline Editor, is actually used only for writing Firebase cloud functions….
NOTE: the code samples that the Dialogflow team used to provide have either been deleted or moved to some completely different GitHub project. I don’t have the bandwidth at the moment to retrace my steps and get the old code. So I suggest you skip this tutorial and find other material elsewhere. Recently Dialogflow announced…
Yeah, I cannot help exaggerating sometimes. 🙂 But this one is not much of an exaggeration. Why webhook development is a big pain in the backside Not just Dialogflow webhooks, but the way webhooks work in general, you might believe that the best way to debug these webhooks is to sprinkle your code with very…
