## MedplumClient.createAttachment() method

Creates a FHIR `Attachment` with the provided data content.

This is a convenience method for creating a `Binary` resource and then creating an `Attachment` element.

The `data` parameter can be a string or a `File` object.

A `File` object often comes from a `<input type="file">` element.

**Signature:**

```typescript
createAttachment(createBinaryOptions: CreateBinaryOptions, requestOptions?: MedplumRequestOptions): Promise<Attachment>;
```

## Parameters

| requestOptions | [MedplumRequestOptions](/content/docs/sdk/core.medplumrequestoptions) | _(Optional)_ Optional fetch options. **NOTE:** only `options.signal` is respected when `onProgress` is also provided. |

**Returns:**

The result of the create operation.

```typescript
const result = await medplum.createAttachment(myFile, 'test.jpg', 'image/jpeg');
