DeleteCertificate

Removes an installed certificate, identified by its hash data.

Version: OCPP 2.0.1
Direction: CSMS → Charge Point
Functional block: Security

Deletion is by hash rather than by name, so the request is unambiguous even when several certificates share a subject.

Request

Field	Type	Required	Description
`certificateHashData`	CertificateHashDataType	Required	`hashAlgorithm`, `issuerNameHash`, `issuerKeyHash` and `serialNumber`.

json

[2, "19223201", "DeleteCertificate", {
  "certificateHashData": {
    "hashAlgorithm": "SHA256",
    "issuerNameHash": "3d8f...",
    "issuerKeyHash": "9b21...",
    "serialNumber": "0a1b2c3d"
  }
}]

Response

Field	Type	Required	Description
`status`	DeleteCertificateStatusEnumType	Required	Result.
`statusInfo`	StatusInfoType	Optional	Reason code.

json

[3, "19223201", {
  "status": "Accepted"
}]

Values

DeleteCertificateStatusEnumType

Value	Meaning
`Accepted`	Deleted.
`Failed`	The station could not delete it.
`NotFound`	No certificate matched the hash.

Implementation notes

Deleting the root that validates your own CSMS certificate disconnects the station permanently. Install the replacement first, confirm with GetInstalledCertificateIds, then delete.

NotFound usually means the certificate was already removed. Treat it as success.
