Easily Add Actions to Flows from Public Web Services (Pilot)
External Services can now import a limited number of specifications for public web services. Supported services include Jira, Dropbox, Instagram, Twitter, Mailchimp, eBay, Walmart, GoToMeeting, Trello, and Medium. Activate as many as 25 actions at a time for each API. Add the actions to your flow from the Action element in Flow Builder. External Services also includes support for the OpenAPI 3.0 specification and a new selector that lets you activate and deactivate specific API operations.
