Autodesk APS Cost API: New Enhancements for Contracts and Attributes

Autodesk APS Cost API Enhancement

We’re excited to share some latest updates to the Autodesk Platform Services (APS) Cost API, bringing enhancements to contract workflows and custom attribute access control.


What’s New

MainContract Support in GET Associations

The associationType field now supports:

  • MainContract

This allows developers to retrieve associations linked directly to main contracts using existing GET actions endpoints, improving consistency across cost management workflows.


Extended Status Support for Main Contracts

The following statuses are now supported when updating main contracts via PATCH main-contracts/:id :

  • draft
  • ​pending
  • approved

This enables more complete lifecycle management of main contracts directly through the API.


Collaborator Access for Custom Attributes

A new field has been added to GET properties responses:

  • collaboratorAccess

This field indicates the level of access granted to collaborators for a custom attribute.

Possible values:

  • no_access
  • view
  • edit

This provides better visibility into permission models and allows applications to reflect and enforce access control more accurately.


Summary

With these updates, developers can:

  • Work more effectively with main contract associations
  • Manage contract lifecycle states more comprehensively
  • Gain clearer insight into collaborator permissions for custom attributes
