GET Certificates Metadata Compare

The GET /Certificates/MetadataClosed Metadata provides information about a piece of data. It is used to summarize basic information about data, which can make working with the data easier. In Keyfactor Command, the certificate metadata feature allows you to create custom metadata fields that allow you to tag certificates with tracking information about certificates./Compare method is used to compare the value of a metadata field in a certificate stored in Keyfactor Command with a provided value. This can be used to prevent exposing sensitive data while still providing functionality. For example, with this method, a metadata attribute can be used along with the certificate itself as a second authentication factor to a third-party application. This method returns HTTP 200 OK on a success with a response of true if the compared values match or false if they do not.

Tip:  The following permissions (see Security Roles and Claims) are required to use this feature:
/certificates/collections/read/
OR
/certificates/collections/read/#/ (where # is a reference to a specific certificate collection ID—see CollectionID, below)

Permissions for certificates can be configured at multiple levels. You can apply them system-wide—for all certificates—or use fine-grained control by assigning permissions at the certificate collectionClosed The certificate search function allows you to query the Keyfactor Command database for certificates from any available source based on any criteria of the certificates and save the results as a collection that will be availble in other places in the Management Portal (e.g. expiration alerts and certain reports). level. The appropriate level depends on how the certificates are accessed. See Certificate Collection Permissions for more information about system-wide versus more targeted permission models.

Table 322: GET Certificates Metadata Compare Input Parameters

Name In Description
certificateId Query Required. An integer containing the Keyfactor Command reference ID of the certificate containing the metadata value to be compared.
metadataFieldName Query Required. A string containing the name of the metadata field whose value should be compared.
value Query Required. A string containing the value for comparison.
collectionId Query

An optional integer that specifies the certificate collection (CollectionId) to validate whether the user has sufficient permissions to perform the action. If a CollectionId is not provided, the user must have appropriate permissions granted system-wide or via certificate store containers.

Providing a CollectionId allows the system to check the user's permissions at the certificate collection level. Permissions are evaluated in the following order:

  1. System-wide certificate permissions
  2. Granular certificate permissions

Use either ContainerId or CollectionId, not both. If both are specified, CollectionId takes precedence, and the ContainerId is ignored (defaults to 0).

See Certificate Collection Permissions for more information.
Tip:  See the Keyfactor API Reference and Utility which provides a utility through which the Keyfactor APIClosed An API is a set of functions to allow creation of applications. Keyfactor offers the Keyfactor API, which allows third-party software to integrate with the advanced certificate enrollment and management features of Keyfactor Command. endpoints can be called and results returned. It is intended to be used primarily for validation, testing and workflowClosed A workflow is a series of steps necessary to complete a process. In Keyfactor Command, it refers to the workflow builder, which allows you to automate event-driven tasks such as when a certificate is requested, revoked or found in a certificate store. development. It also serves secondarily as documentation for the API.
