Hi Joseph,
Thanks for testing on 2026.3.7.0, and no worries about the delay. The change in the message is good news: the vault and permission part is now working, and the remaining error is only about the request body.
Yes, Credential entries can be created through the API. The request is missing one field: "subType". For a username and password credential it must be set to "Default". Without it, the server rejects the request with the "entry type is not supported for creation" message.
Here is your request with the field added:
{
"name": "TEST Upload",
"description": "wdw",
"path": "",
"type": "Credential",
"subType": "Default",
"tags": [],
"data": {
"domain": "your domain",
"username": "hello",
"password": "hello"
}
}
Please keep "type" as "Credential" (singular), as you already have it. Please also send this to the same URL as before: /api/v1/vault/{vault id}/entry.
If you later need other kinds of credentials, the subType changes accordingly (for example "PrivateKey" or "ApiKey"). You can list the available types and subTypes with a GET request to /api/v1/entry/definition.
Please let us know if the entry gets created.
Best regards,
