Variable sets API reference

A variable set is a resource that allows you to reuse the same variables across multiple workspaces and projects. For example, you could define a variable set of provider credentials and automatically apply it to a selection of workspaces, all workspaces in a project, or all workspaces in an organization.

You need Read variables permission to view the variables for a particular workspace and to view the variable sets in the owning organization. To create or edit variable sets, your team must have Manage all workspaces organization access.

Create a Variable Set

POST organizations/:organization_name/varsets

Parameter	Description
`:organization_name`	The name of the organization the workspace belongs to.

Request Body

Properties without a default value are required.

Key path	Type	Default	Description
`data.attributes.name`	string		The name of the variable set.
`data.attributes.description`	string	`""`	Text displayed in the UI to contextualize the variable set and its purpose.
`data.attributes.global`	boolean	`false`	When true, HCP Terraform automatically applies the variable set to all current and future workspaces in the organization.
`data.attributes.priority`	boolean	`false`	When true, the variables in the set override any other variable values with a more specific scope, including values set on the command line.
`data.relationships.workspaces`	array	`[]`	Array of references to workspaces that the variable set should be assigned to.
`data.relationships.projects`	array	`[]`	Array of references to projects that the variable set should be assigned to.
`data.relationships.vars`	array	`[]`	Array of complete variable definitions that comprise the variable set.

HCP Terraform does not allow different global variable sets to contain conflicting variables with the same name and type. You will receive a 422 response if you try to create a global variable set that contains conflicting variables.

Status	Response	Reason(s)
200	JSON API document	Successfully added variable set
404	JSON API error object	Organization not found, or user unauthorized to perform action
422	JSON API error object	Problem with payload or request; details provided in the error object

Variable Relationships

Add Variable

POST varsets/:varset_external_id/relationships/vars

Parameter	Description
`:varset_id`	The variable set ID

Request Body

This POST endpoint requires a JSON object with the following properties as a request payload.

Properties without a default value are required.

Key path	Type	Default	Description
`data.type`	string		Must be `"vars"`.
`data.attributes.key`	string		The name of the variable.
`data.attributes.value`	string	`""`	The value of the variable.
