# [BETA] Delete an existing context field

DELETE https://app.unleash-instance.example.com/api/admin/projects/{projectId}/context/{contextField}

**[BETA]** This API is in beta state, which means it may change or be removed in the future.

Endpoint that allows deletion of a custom context field. Does not validate that context field is not in use, but since context field configuration is stored in a json blob for the strategy, existing strategies are safe.
