# Button API

Give commands for getting presses from a physical button.
> Source: https://docs.viam.com/reference/apis/components/button/


The button API allows you to get button presses from your [button components](/reference/components/button/).

The button component supports the following methods:

| ----------- | ----------- | --------------------------- |
| [`Push`](/reference/apis/components/button/#push) | Push the button. | <p class="center-text"><i class="fas fa-check" title="yes"></i></p> |
| [`Reconfigure`](/reference/apis/components/button/#reconfigure) | Reconfigure this resource. |  |
| [`DoCommand`](/reference/apis/components/button/#docommand) | Execute model-specific commands that are not otherwise defined by the component API. | <p class="center-text"><i class="fas fa-check" title="yes"></i></p> |
| [`GetStatus`](/reference/apis/components/button/#getstatus) | Get the current status of the button as a map of key-value pairs describing its state. |  |
| [`GetResourceName`](/reference/apis/components/button/#getresourcename) | Get the `ResourceName` for this button. |  |

### DoCommand

Execute model-specific commands that are not otherwise defined by the component API.
Most models do not implement `DoCommand`.
Any available model-specific commands should be covered in the model's documentation.
If you are implementing your own button and want to add features that have no corresponding built-in API method, you can implement them with [`DoCommand`](/reference/sdks/docommand/).
Supported by `viam-micro-server`.

**Parameters:**

- `command` (Mapping[[str](https://docs.python.org/3/library/stdtypes.html#text-sequence-type-str), ValueTypes]) (required): The command to execute.
- `timeout` ([float](https://docs.python.org/3/library/stdtypes.html#numeric-types-int-float-complex)) (optional): An option to set how long to wait (in seconds) before calling a time-out and closing the underlying RPC call.

**Returns:**

- (Mapping[[str](https://docs.python.org/3/library/stdtypes.html#text-sequence-type-str), viam.utils.ValueTypes]): :   Result of the executed command.

**Raises:**

- (NotImplementedError): Raised if the Resource does not support arbitrary commands.
