Inputs

Every action gets its data from an input. That's either request data / a previous action's output selected with input:, or a fetch from an external source.

Source	Use it for	Reference
http	Call any HTTP/REST API	HTTP requests
database	Query SQL and NoSQL databases	Databases
command	Run CLI tools, scripts, curl	Command
email	Send email over SMTP	Email

Select request data or an earlier action's output with the closed marker form:

actions:
  - name: CheckBody
    input: a|body|
  - name: Fetch
    http:
      url: https://api.example.com/users/a|params::id|
  - name: Use
    input: a|Fetch::email|
