--- title: "Creates or Updates MeshFaultInjection entity" method: PUT path: "/v1/mesh/control-planes/{cpId}/api/meshes/{mesh}/meshfaultinjections/{name}" tags: ["MeshFaultInjection"] --- # Creates or Updates MeshFaultInjection entity `PUT /v1/mesh/control-planes/{cpId}/api/meshes/{mesh}/meshfaultinjections/{name}` ## Path parameters - `mesh` string, required - `name` string, required ## Request body - MeshFaultInjectionItem — MeshFaultInjection allows you to test the resiliency of your services by injecting faults like delays, connection aborts, and response bandwidth limits into the traffic. This is useful for chaos testing and validating that your applications handle failures gracefully. - `type` 'MeshFaultInjection', required — the type of the resource - `mesh` string — Mesh is the name of the Kuma mesh this resource belongs to.
