Create a variable

The `filter` parameter

Introduced in GitLab 13.2.

Feature flag removed in GitLab 13.4.

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"
