--- layout: example.html title: Sentinel Hub shortdesc: A tile source using the Sentinel Hub Processing API docs: > This example renders a tile layer with a source that uses the Sentinel Hub [Processing API](https://docs.sentinel-hub.com/api/latest/api/process/) to generate tiles. The Processing API requires an access token. The form above can be used to provide an OAuth client id and secret. The default client id and secret used in this example is severely rate limited. For the example to perform well, you should register for your own client id and secret. With this information, the source will fetch an access token. If an accesss token is fetched by other means, the `source.setAuth()` method can be called the token directly. See the Sentinel Hub [authentication documentation](https://docs.sentinel-hub.com/api/latest/api/overview/authentication/) for details.
See these other examples for details on the following:
source.setData()
to update the time range for the input data.
source.setEvalscript()
to update the Evalscript used in rendering tiles.
