Config API

Config endpoints are nested under tenants. All endpoints require authentication and enforce tenant scope for scoped API keys.

Endpoints

Method	Path	Description
GET	/api/v1/tenants/:id/config	Get resolved config
PUT	/api/v1/tenants/:id/config/:key	Set config value
DELETE	/api/v1/tenants/:id/config/:key	Delete config override
PUT	/api/v1/tenants/:id/config/batch	Batch set (up to 200, atomic)
GET	/api/v1/tenants/:id/config/inheritance	Get full inheritance view

Get Resolved Config

GET /api/v1/tenants/:id/config

Returns resolved config for the tenant with all inheritance applied. Walks up the ancestry path and merges entries.

Response: 200 OK

{
  "max_users": {
    "key": "max_users",
    "value": 500,
    "source_tenant_id": "msp-uuid",
    "inherited": true,
    "locked": false
  },
  "theme": {
    "key": "theme",
    "value": "dark",
    "source_tenant_id": "root-uuid",
    "inherited": true,
    "locked": true
  }
}

Each entry tells you:

Field	Description
value	The effective value (any JSON type)
source_tenant_id	Which tenant set this value
inherited	true if the value came from an ancestor
locked	true if no descendant can override this key

---

Set Config Value

PUT /api/v1/tenants/:id/config/:key

Body:

{
  "value": "any JSON value",
  "locked": false,
  "sensitive": false
}

Field	Type	Default	Description
value	any	Required	The config value (string, number, boolean, object, array)
locked	boolean	false	Prevent descendants from overriding
sensitive	boolean	false	Encrypt at rest with AES-256-GCM

Returns 409 CONFIG_LOCKED if the key is locked by an ancestor.

Response: 200 OK – returns the config entry.

---

Delete Config Override

DELETE /api/v1/tenants/:id/config/:key

Removes the tenant’s override for this key. If an ancestor has set the key, the tenant reverts to inheriting that value.

Response: 204 No Content

---

Batch Set Config

PUT /api/v1/tenants/:id/config/batch

Sets up to 200 config keys in a single atomic transaction. If any key is locked by an ancestor, the entire batch rolls back.

Body:

{
  "entries": [
    {"key": "max_users", "value": 500, "locked": false},
    {"key": "theme", "value": "dark", "locked": true},
    {"key": "api_secret", "value": "sk_live_abc", "sensitive": true}
  ]
}

Each entry in the entries array supports the same fields as the single PUT endpoint (value, locked, sensitive), plus a key field.

Limits:

• Maximum 200 entries per batch
• Empty arrays return 400 VALIDATION_ERROR

Response: 200 OK – returns array of config entries.

---

Get Config Inheritance

GET /api/v1/tenants/:id/config/inheritance

Returns the full config with inheritance metadata – showing which level set each value, whether it is inherited or overridden, and the full ancestry chain.

Response: 200 OK
