Response Structure

The response returns a string of type application/json with the following body parameters:


Parameter	Description
`response`	Indicates the status of the update operation. Type: String or Object.
`message`	Success or error message. Type: String.
`appStatusCode`	Application-specific status code for the response. Non-null for failure responses. Type: String.
`tags`	Additional information in case of a failure response.

Status Codes


HTTP Status	appStatusCode	Description
`200 OK`	null	CA policy updated successfully.
`400 Bad Request`	`MANDATORY_POLICY_NAME`	Policy name is missing or empty. Remediation: Provide a value for `policyName` (2–64 characters).
`400 Bad Request`	`KEY_DETAILS_VALIDATION_FAILED`	Validation failed for the key details in the policy. Remediation: Verify that `keyDetails` contains valid algorithm, bit length, and hash algorithm values.
`400 Bad Request`	`CRL_SIGN_MUST_PRESENT_IN_KU_FOR_CRL_PUBLISH`	`crlPublish` is set to `true` but `crlSign` is not included in `ku`. Remediation: Add `crlSign` to the `ku` array.
`400 Bad Request`	`INVALID_OCSP_SIGNING_CERTIFICATE_ALGORITHM`	EC is not a valid algorithm for `defaultOcspSigningCertificate`. Remediation: Use a non-EC classical algorithm.
`400 Bad Request`	`INVALID_OCSP_CSR_GENERATION_TYPE`	HSM is not a valid value for `defaultCsrGenerationForOcspSigningCertificate`. Remediation: Use `AppViewX`.
`401 Unauthorized`	`AVX_GW_003`	Authentication failed — invalid credentials. Remediation: Provide a valid `username` and `password` or a valid `sessionId`.
`403 Forbidden`	`USER_POLICY_WRITE_ACCESS_RESTRICTED`	The authenticated user does not have write access to CA policies. Remediation: Contact your AppViewX administrator to grant the required permissions.
`404 Not Found`	`USER_POLICY_NOT_FOUND`	No CA policy found with the specified name. Remediation: Use the `List CA Policies` API to confirm the exact `policyName`.

Understanding the sample URL

IP/HostName/TenantName: Replace with the actual IP address, hostname, or tenant name based on the specific configuration in AppViewX.
- IP: A unique identifier assigned to each device connected to a computer network that uses the Internet Protocol for communication
  The IP address will be included in the endpoint URL for an on-prem deployment.
- HostName: A human-readable label assigned to a device (host) on a network
  The hostname will be included in the endpoint URL for an on-prem deployment.
- TenantName: An identifier label for a tenant given to indicate which tenant's data the API request will access/modify
  The tenant name will be included in the endpoint URL for a SaaS deployment.
GWPORT: AppViewX gateway port
A gateway port refers to a network port through which data is sent and received to communicate with a gateway in an on-prem deployment.
Example: 31443
avxapi: Path parameter value (static) that is part of the endpoint's URL
Endpoint: Endpoint of the API, for example: execute-hook
gwsource: Source or origin of a gateway, for example: external.
