Need help in creating Certification Campaign using REST API

You can’t use the searchCampaignInfo object if you select the MANAGER campaign type. You will get a 400 Bad Request. I think the easiest way to generate a manager certification with specific identities is to use the searchCampaignInfo object and make the reviewerId your manager and the identityIds array the list of specific reports for the manager. For example:

{
    "name": "Manager Campaign",
    "description": "Campaign for manager with a subset of identities",
    "type": "SEARCH",
    "searchCampaignInfo": {
        "type": "IDENTITY",
        "reviewerId": "2c9180867624cbd7017642d8c8c81f67", // The manager
        "identityIds": ["2c918085771b670d01771c567e650913"] // One or more specific identities that report to the manager
    }
}
