# GRIDType

> Abstract base class for all GRID Robot API types

```python theme={null}
from grid_types import GRIDType
```

Abstract base class for all GRID Robot API types.

All serializable types used as return values in the GRID Robot API
should inherit from this class and implement to\_dict() and from\_dict().

## Methods

### `from_dict()`

```python Signature theme={null}
from_dict(data: dict) -> GRIDType
```

Deserialize from dictionary. Please ensure any nested types
are also deserialized correctly or are converted from a serializable format in this method.

<ParamField body="data" type="dict" required>
  Dictionary containing serialized object data
</ParamField>

**Returns:**

GRIDType: Reconstructed object

### `to_dict()`

```python Signature theme={null}
to_dict() -> dict
```

Serialize to dictionary for JSON transfer. Please ensure any nested types
are also JSON serializable or are converted to a serializable format in this method.

**Returns:**

dict: Dictionary representation of the object
