API Availability & Access

The API is included for Organizations with a paid ULTIMATE PlanAPI Access is under Administration in the left-side navigation. The API Access button is disabled for workspaces that do not have the API enabled.

Token-Based Authentication

LP API access

The LiquidPlanner API supports token-based authentication which uses a unique token identifier to make authenticated API requests on behalf of a workspace member.

Org Admin access is required in order to view, create and manage tokens.

Creating Tokens

Navigate to Administration > API Access and use the Create New Token button. Assign the token to another workspace member by selecting them from the drop down menu in the Token Owner column. Members can have more than one token assigned.

Managing Tokens

The default name for a new token is “New API Token for [Username]”. The name field is customizable. Tokens are enabled by default. Uncheck the box to disable a token.

Token Owners

Only workspace members can be Token Owners. When an Organization has multiple workspaces, a Token Owner’s API authorization only applies in the workspaces where they are an active member.

  • API Tokens inherit the Token Owner’s access level.
    • Token Owners with Project Editor access or higher are able to make changes via their API Token.
    • Updates made with an API Token are recorded in Changes and attributed to the Token Owner.
  • Disconnecting a member disables their tokens. Disconnected token owners are listed in red in the Token Owner column.
