If this results in a new root certificate being used, the [Root Rotation](/docs/connect/ca#root-certificate-rotation) process will be triggered. | Method | Path | Produces | | ------ | --------------------------- | ------------------ | | `PUT` | `/connect/ca/configuration` | `application/json` | The table below shows this endpoint's support for [blocking queries](/api/features/blocking), [consistency modes](/api/features/consistency), [agent caching](/api/features/caching), and [required ACLs](/api#authentication). | Blocking Queries | Consistency Modes | Agent Caching | ACL Required | | ---------------- | ----------------- | ------------- | ---------------- | | `NO` | `none` | `none` | `operator:write` | ### Parameters - `Provider` `(string: )` - Specifies the CA provider type to use. - `Config` `(map[string]string: )` - The raw configuration to use for the chosen provider. For more information on configuring the Connect CA providers, see [Provider Config](/docs/connect/ca). - `ForceWithoutCrossSigning` `(bool: )` - Indicates that the CA change should be force to complete even if the current CA doesn't support cross signing. Changing root without cross-signing may cause temporary connection failures until the rollout completes. See [Forced Rotation Without Cross-Signing](/docs/connect/ca#forced-rotation-without-cross-signing) for more detail. ### Sample Payload ```json { "Provider": "consul", "Config": { "LeafCertTTL": "72h", "PrivateKey": "-----BEGIN RSA PRIVATE KEY-----...", "RootCert": "-----BEGIN CERTIFICATE-----...", "RotationPeriod": "2160h", "IntermediateCertTTL": "8760h" }, "ForceWithoutCrossSigning": false } ``` ### Sample Request ```shell-session $ curl \ --request PUT \ --data @payload.json \ http://127.0.0.1:8500/v1/connect/ca/configuration ```
