Connector Types

Connectors are the Cloudomation Engine functions that allow your flow scripts to interact with the outside world - anything and everything outside of the Engine platform. Whenever you want to issue a command to a program, run a script on a remote system, or get query a database - all that is performed through connectors.

There are different connector types, each for a particular type of endpoint / protocol.

Connectors are called through the Engine function this.connect(). Each call creates a separate execution of type "connection", with its own inputs and outputs.

For example, you can call a REST API using the Engine REST connector type:

import flow_api

def handler(system: flow_api.System, this: flow_api.Execution, inputs: dict):
    inputs = {
        'url': 'https://httpbin.org/post',
        'method': 'post',
        'data': 'payload',
    }
    child_execution = this.connect(connector_type='REST', **inputs, run=False)
    child_execution.run_async()
    # do other stuff
    child_execution.wait()
    outputs = child_execution.get('output_value')
    this.log(outputs)
    return this.success('all done')

The inputs required and outputs supplied by a connection depend on the connector type. Below your find documentation on each of the currently available connector types.
