Cancel tasks API

The Lattice SDK now supports task cancellation through the CancelTask API available in both REST and gRPC. This API lets an operator request to cancel, giving you greater control over task lifecycle management.

The cancellation behavior depends on the task’s current state:

  • Tasks not yet sent to an agent cancel immediately and transition to a terminal state.
  • Tasks already sent to an agent receive a cancellation request that the agent can accept or reject based on the task’s execution state.

For more information on using the CancelTask API in your integration, see Cancel tasks in the Lattice SDK guide.

For API reference details, see CancelTask (REST) and CancelTask (gRPC).
