  • method (str | None) – The Slack API Method to Call (https://api.slack.com/methods).

  • api_params (dict | None) – API Method call parameters (https://api.slack.com/methods). Optional

hook()[source]

Slack Hook.

abstract construct_api_call_params()[source]

Construct API call parameters used by the execute function.

Allow templating on the source fields of the api_call_params dict before construction.

Child classes should override this. Each SlackAPIOperator child class is responsible for having function set self.api_call_params with a dict of API call parameters (https://api.slack.com/methods)

execute(context)[source]

Derive when creating an operator.

Context is the same dictionary used as when rendering jinja templates.

Refer to get_template_context for more context.
