# GraphQL API
## Defining the Schema Class
A plugin can extend NetBox's GraphQL API by registering its own schema class. By default, NetBox will attempt to import `graphql.schema` from the plugin, if it exists. This path can be overridden by defining `graphql_schema` on the PluginConfig instance as the dotted path to the desired Python class.
### Example
```python
# graphql.py
import strawberry
import strawberry_django
from . import models
@strawberry_django.type(
models.MyModel,
fields='__all__',
)
class MyModelType:
pass
@strawberry.type
class MyQuery:
@strawberry.field
def dummymodel(self, id: int) -> DummyModelType:
return None
dummymodel_list: list[DummyModelType] = strawberry_django.field()
schema = [
MyQuery,
]
```
## GraphQL Objects
NetBox provides two object type classes for use by plugins.
::: netbox.graphql.types.BaseObjectType
options:
members: false
::: netbox.graphql.types.NetBoxObjectType
options:
members: false
## GraphQL Filters
NetBox provides a base filter class for use by plugins which employ subclasseses of `NetBoxModel`.
::: netbox.graphql.filters.NetBoxModelFilter
options:
members: false
Additionally, the following filter classes are available for subclasses of standard base models.
| Model Class | FilterSet Class |
|-----------------------|----------------------------------------------------|
| `PrimaryModel` | `netbox.graphql.filters.PrimaryModelFilter` |
| `OrganizationalModel` | `netbox.graphql.filters.OrganizationalModelFilter` |
| `NestedGroupModel` | `netbox.graphql.filters.NestedGroupModelFilter` |
