# Add User Property

`PUT /{databaseId}/users/properties/{propertyName}`

Adding a user property is somewhat equivalent to adding a column to the table of users. The users may be characterized by various properties of different types.

## Path parameters

- `databaseId` string, required
- `propertyName` string, required

## Query parameters

- `type` 'int' | 'double' | 'string' | 'boolean' | 'timestamp' | 'set', required

## Response `201`

Successful operation.

## Other responses

- `400` — Property name does not match ^[a-zA-Z0-9_\-:]+$, or it is a reserved keyword (''id'', ''userid''), or its length exceeds 63 characters. Type information is missing, or the given type is invalid.
- `409` — Property of the given name is already present in the database. In many cases, you may consider this code a success – it only tells you that nothing has been written to the database.
