This article will offer a step by step approach to creating a Facebook messenger chatbot that will run on aws lambda.

The only tools you will need are nodejs, a text editor and a browser.

If you are in a hurry, and know your way around lambda, api gateway and facebook apps, you can get the code for the lambda function for a fully functional bot here, and the swagger api definition to import into api gateway here.

If you want a step by step walkthrough of how you set it all up, here we go…

Duration is calculated from the time your code begins executing until it returns or otherwise terminates, rounded up to the nearest 100ms. The price depends on the amount of memory you allocate to your function. You are charged $0.00001667 for every GB-second used. In…
