Tutorial: Build a Serverless API Back-end for Slack
See the original posting on DZone Python
Webhook backends are a popular use case for Serverless functions. FaaS (Functions-as-a-service) offerings make it relatively easy to provide an HTTP endpoint which hosts the Webhook logic which can be as simple as sending an email to something as entertaining as responding with funny GIFs!
In this tutorial, we will explore funcy a Serverless webhook backend which is a trimmed down version of the awesome Giphy for Slack. The (original) Giphy Slack app returns a bunch of GIFs for a search term, and the user can pick one of them. Funcy tweaks it a bit by simply returning a (single) random image for a search keyword using the Giphy Random API.
