Get a single variable

Get the details of a single variable. If there are multiple variables with the same key, use filter to select the correct environment_scope.

GET /projects/:id/variables/:key
Attribute Type Required Description
id integer/string Yes ID or URL-encoded path of the project
key string Yes The key of a variable
filter hash No Available filters: [environment_scope]. See the filter parameter details.
curl --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/1/variables/TEST_VARIABLE_1"

    "protected": false,
    "masked": true,
    "raw": false,
    "environment_scope": "*",

Create a variable

Create a new variable. If a variable with the same key already exists, the new variable must have a different environment_scope. Otherwise, GitLab returns a message similar to: VARIABLE_NAME has already been taken.

POST /projects/:id/variables
Attribute Type Required Description

protected boolean No Whether the variable is protected. Default: false
masked boolean No Whether the variable is masked. Default: false
raw boolean No Whether the variable is treated as a raw string. Default: false. When true, variables in the value are not expanded.

curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" \
     "https://gitlab.example.com/api/v4/projects/1/variables" --form "key=NEW_VARIABLE" --form "value=new value"

    "value": "new value",
    "protected": false,
    "masked": false,
    "raw": false,
    "environment_scope": "*",
    "description": null

DELETE /projects/:id/variables/:key
Attribute Type Required Description
id integer/string Yes ID or URL-encoded path of the project
key string Yes The key of a variable

curl --request DELETE --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/1/variables/VARIABLE_1"

The filter parameter

When multiple variables have the same key, GET, PUT, or DELETE requests might return:

There are multiple variables with provided parameters. Please use 'filter[environment_scope]'.

Use filter[environment_scope] to select the variable with the matching environment_scope attribute.

For example:

  • GET:

    curl --globoff --header "PRIVATE-TOKEN: <your_access_token>" \
         "https://gitlab.example.com/api/v4/projects/1/variables/SCOPED_VARIABLE_1?filter[environment_scope]=production"
  • PUT:

    curl --request PUT --globoff --header "PRIVATE-TOKEN: <your_access_token>" \
         "https://gitlab.example.com/api/v4/projects/1/variables/SCOPED_VARIABLE_1?value=scoped-variable-updated-value&environment_scope=production&filter[environment_scope]=production"
  • DELETE:

    curl --request DELETE --globoff --header "PRIVATE-TOKEN: <your_access_token>" \
         "https://gitlab.example.com/api/v4/projects/1/variables/SCOPED_VARIABLE_1?filter[environment_scope]=production"
