## BackendSrv interface
Used to communicate via http(s) to a remote backend such as the Grafana backend, a datasource etc. The BackendSrv is using the [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) under the hood to handle all the communication.
The request function can be used to perform a remote call by specifying a [BackendSrvRequest](./runtime/backendsrvrequest.md). To make the BackendSrv a bit easier to use we have added a couple of shorthand functions that will use default values executing the request.
Signature
```typescript
export interface BackendSrv
```
Import
```typescript
import { BackendSrv } from '@grafana/runtime';
```
## Remarks
By default Grafana will display an error message alert if the remote call fails. If you want to prevent this from happending you need to catch the error thrown by the BackendSrv and set the `isHandled = true` on the incoming error.
