Slack2Watson (1): Connect API Connect to Serverless OpenWhisk

‘Slack2Watson (1): Connect API Connect to Serverless OpenWhisk’ is part 1 of an application called Slack2Watson, which integrates a ChatBot into Slack and allows you to retrieve information about events via Slash Commands in Slack. In part 1, I will set up the ‘API Connect’ service and link the APIs in ‘API Connect’ to the OpenWhisk functions.

Integration is managed using API management in ‘API Connect,’ serverless or event-based APIs in OpenWhisk, and IBM Watson to create the Conversation bot. Some data is retrieved via Google Sheets API.

  1. Create API Connect API v1.0.0
  2. Publish the API
  3. Create an OpenWhisk action
  4. Connect API Connect to OpenWhisk
