Multi-tenancy in Permify refers to an authorization architecture where a single Permify authorization service serves multiple applications/organizations (tenants).

This allows customization of the authorization for each tenant’s specific needs. With Multi-Tenancy support, you can create a custom authorization schema and authorization data for the different tenants and manage them in a single place.

For the users that don’t have/need multi-tenancy in their authorization structure, we created a pre-inserted tenant (id: t1) that comes default when you serve a Permify service.

​
Tenancy Based APIs

Almost all Permify API endpoints have a ‍tenant_id mandatory field. Let’s examine a check request below,

​
Check API

cr, err: = client.Permission.Check(context.Background(), & v1.PermissionCheckRequest {
    TenantId: "t1",
    Metadata: & v1.PermissionCheckRequestMetadata {
        SnapToken: ""
        SchemaVersion: ""
        Depth: 20,
    },
    Entity: & v1.Entity {
        Type: "repository",
        Id: "1",
    },
    Permission: "edit",
    Subject: & v1.Subject {
        Type: "user",
        Id: "1",
    },

    if (cr.can === PermissionCheckResponse_Result.RESULT_ALLOWED) {
        // RESULT_ALLOWED
    } else {
        // RESULT_DENIED
    }
})

Users that come from version 0.2.x and users that have a single tenant can enter t1 as tenant id. See changes on the other endpoints from API Overview Section.

​
Tenancy Service

To manage tenants we have added a Tenancy service; you can create, delete and list tenants. See the Tenancy Service in Using The API section.

​
Permission Database

​
Tenant Table

A tenants table has been added to the Permissions database to store tenants’ details.

tables
├── migrations       
├── relation_tuples   
├── schema_definitions   
├── tenants   
├── transactions

​
Tenant ID Column

Authorization DATA and schema definition tables now have a tenant_id column, which stores the id of the tenant that the data belongs.

Let’s take a look at a snapshot of the demo table on an example Permission Database.

Example Relation Tuples data table: tenant-id-tuples

Example Schema Definitions data table tenant-id-schema
