# Tenant Mutation

### Mutation Types

{% hint style="info" %}
Mutations are responsible to insert or update a specific register, the operation insert or update is defined by **`externalId`**, in case this tenant was imported previously, this mutation will updated the resource, otherwise will create the tenant. If you wish to update the externalId, pass EverReal UUID as id in the mutation payload along with the changed externalId
{% endhint %}

```graphql
type Mutation {
    upsertTenant(tenant: TenantInput): Tenant
    deleteTenant(externalId: String): AsyncEventResponse
    removeTenant(id: String): Boolean
}
```

Here are details on the capabilities of different mutations

* The `upsertTenant`  mutation is used to create or update a tenant in Everreal system and tenant added to the system cannot be modified by Everreal and if needs to be modified it should be done via the same endpoint itself.
* The `deleteTenant`  mutation is used to delete the tenant relation with the external integration source, doing this will not delete the tenant but instead it will remain as a detached tenant from integration and can be modified using Everreal.
* The `removeTenant` mutation is used to remove the tenant from the system, in order to perform removeTenant, please make sure that all the contracts assosiated with the tenant is been removed ( [reference](/endpoints/contract/contract-mutation.md) to delete contract)
