Applications

Applications are OAuth2 clients registered in a workspace. They represent pieces of software — SPAs, mobile apps, backend services — that authenticate users or request tokens from Kotauth.

Required scopes: applications:read for GET requests, applications:write for PUT / DELETE.

Application object

{
  "id": 5,
  "clientId": "my-spa",
  "name": "My SPA",
  "description": "Frontend web application",
  "accessType": "public",
  "enabled": true,
  "redirectUris": [
    "https://app.yourdomain.com/callback",
    "http://localhost:3000/callback"
  ],
  "audience": "https://api.yourdomain.com"
}

Field	Type	Description
`id`	integer	Internal numeric ID
`clientId`	string	The OAuth2 `client_id` — what you pass to OAuth2 libraries
`name`	string	Human-readable application name
`description`	string \| null	Optional description
`accessType`	`public` \| `confidential`	Public = no secret, must use PKCE; Confidential = has client secret
`enabled`	boolean	`false` = disabled, blocks new logins
`redirectUris`	string[]	Allowed OAuth2 redirect URIs
`audience`	string \| null	Custom JWT `aud` claim. Falls back to `clientId` if null. Max 200 characters.

Get an application

GET /t/{slug}/api/v1/applications/{appId}

Path parameters:

Parameter	Type	Description

Response 200 OK: Returns the application object.

Update an application

PUT /t/{slug}/api/v1/applications/{appId}

Updates the application’s name, description, access type, and allowed redirect URIs. Changing accessType between public and confidential affects which OAuth2 flows the app can use.

Request body:

{
  "name": "My SPA v2",
  "description": "Updated frontend application",
  "accessType": "public",
  "redirectUris": [
    "https://app.yourdomain.com/callback",
    "https://staging.yourdomain.com/callback"
  ]
}

Field	Required	Description
`name`	Yes	Display name
`description`	No	Optional description (pass `null` to clear)
`accessType`	Yes	`public` or `confidential`
`redirectUris`	Yes	Array of allowed redirect URIs. Must be exact matches.

Response 200 OK: Returns the updated application object.

Get default roles

GET /t/{slug}/api/v1/applications/{appId}/default-roles

Returns the roles that are automatically assigned to users who self-register through this application (via password signup, social login, or Email OTP).

Required scope: applications:read

Response 200 OK:

{
  "data": [
    { "id": 3, "name": "viewer", "description": "Read-only access", "composite": false }
  ],
  "meta": { "total": 1 }
}

Set default roles

PUT /t/{slug}/api/v1/applications/{appId}/default-roles
Content-Type: application/json

{
  "roleIds": [3, 7]
}

Replaces the full set of default roles for the application. Pass an empty array to clear all default roles.

Required scope: applications:write

Field	Required	Description
`roleIds`	Yes	Array of role IDs to auto-assign at registration. Full-set replace.

Response 200 OK: Returns the updated default roles in the same format as the GET endpoint.

Disable an application

DELETE /t/{slug}/api/v1/applications/{appId}

Soft-disables the application. New authorization requests are rejected, but existing valid tokens continue to work until they expire.

To re-enable a disabled application, use the admin console.

Response 204 No Content
