# Retrieve the objectives of a plan solution



## OpenAPI

````yaml /openapi.yaml get /plans/{planId}/solution/objectives
openapi: 3.0.3
info:
  title: Kardinal Builder API
  version: 1.0.0
  description: >
    This document specifies the REST API of Kardinal for builder users.


    Every endpoint applies to the single agency carried by the access token
    (either the sandbox

    agency or the production agency), which is why no agency id appears in the
    paths. An access

    token that does not grant access to exactly one agency is rejected with a
    `403`.
