Body Params
string
required
\S

A flow slug in the format workflow-slug/flow-name. An optional version can be appended (workflow-slug/flow-name:version). If no version is provided, the latest version is used. Cannot be blank.

input
required

Input data for a flow. Can be either an array (for positional arguments) or an object (for named parameters).

string
length between 1 and 255

A client-generated key that makes starting a task run safe to retry. Repeating a request with the same key within 24 hours returns the task run that the first request started instead of starting another one; the repeated request's input is ignored. Keys are scoped to a workflow. Omit the key to always start a new run.
