Build a Facebook Chatbot in Python
Nowadays there are many articles like ‘build a chatbot without any code’. But somebody still feels comfortable with codes. I’ll tell you here about to build a Facebook Messenger chatbot rapidly with BotHub.Studio.
Creating a Facebook Messenger Bot
(You need to have a Facebook page to link a Facebook Messenger chatbot .)
Let’s create an app. Move to Facebook developer site.
Create a new app.
Enter a bot name and contact email.
Now you can see a dashboard like below. You can find an App ID and App Secret Code here.
Add a product to the app. Click
Set Up button in Messenger section.
Link it to your Facebook page. Then you can find a Page Access Token there.
Note three entries below to deploy your chatbot to hosting service later.
- App ID
- App Secret Code
- Page Access Token
Setup Hosting for Bot
First, create an account on BotHub.Studio, a chatbot hosting service for developers, and install CLI tool using the command below:
$ pip install bothub-cli
$ bothub configure
Create a project directory:
$ mkdir MyBot
$ cd MyBot
$ bothub init
A template code will be generated after
| |-- bot.py
| `-- __init__.py
Primary template code, specifically
bot.py contains an echo bot code which mimics a user message.
Now we use the facebook credentials you note:
$ bothub channel add facebook --page-access-token=<token> \
And deploy the project to server:
$ bothub deploy
Send a message to your chatbot and see it works well. Search your Facebook page name on Facebook Messenger, then you can talk to your chatbot.
