## Configuration
To configure external pipeline validation:
1. Set the `EXTERNAL_VALIDATION_SERVICE_URL` environment variable to the external
service URL.
1. Enable the `ci_external_validation_service` feature flag.
To configure external pipeline validation, add the
[`EXTERNAL_VALIDATION_SERVICE_URL` environment variable](environment_variables.md)
and set it to the external service URL.
By default, requests to the external service time out after five seconds. To override

## External pipeline validation service
The [external CI/CD pipeline validation service](../../administration/external_pipeline_validation.md)
is available for use on self-managed GitLab instances, but is not in use on GitLab.com.
It is configured with [environment variables](../../administration/environment_variables.md)
on the instance.
To enable the feature on GitLab.com, enable the `ci_external_validation_service`
[feature flag](../feature_flags/index.md). The valid "Not accepted" response code
for GitLab.com is `406` only.
For more details, see the linked issues and MRs in the
[feature flag rollout issue](https://gitlab.com/gitlab-org/gitlab/-/issues/325982).
