        A utility API that can be used to validate the user configuration before activating a certificate issuer. Verifies that the certificate issuer is accessible and can be used to generate certificates by Device Management. <br> **Note:** The API requests the 3rd party CA to sign a test certificate. For some 3rd party CAs, this operation may make use of the account quota. <br> **Example usage:**  ``` curl -X POST \\ -H 'authorization: <valid access token>' \\ -H 'content-type: application/json;charset=UTF-8' \\ https://api.us-east-1.mbedcloud.com/v3/certificate-issuers/01621a36719d507b9d48a91b00000000/verify ```   # noqa: E501
