Unable to run API request under additional administrator account: Can not find client by login

Symptoms

• Unable to run an API request due to the following error:

  # curl -k -u johndoe:@password -X POST -d @domain.json "https://203.0.113.2:8443/api/v2/domains"
  
  {
  "code": 0,
  "message": "Can not find client by login 'johndoe'"
  }

• The johndoe account is the additional Plesk administrator account.

• There is a possibility to login to Plesk under the johndoe account using the same password as in the failed API request.

Cause

API requests cannot be executed under additional Plesk administrator accounts.

It is the Plesk bug #EXTREST-87 which will be fixed in future product updates.

Resolution

As a workaround, execute API request under the main Plesk administrator account:

# curl -k -u admin:@password -X POST -d @domain.json "https://203.0.113.2:8443/api/v2/domains"

{
"id": 4,
"guid": "2442355f-0ddb-4e9e-8c97-716459b2d528"
}
