For compatibility reason, when you activate the rest provider, you can use `web` or `rest` as `provider` value.
|
||||
But be careful, in the configuration for all providers the key is still `web`.

!!! danger "DEPRECATED"
|
||||
The web provider is deprecated, please use the [api](/configuration/api.md), the [ping](/configuration/ping.md), the [metrics](/configuration/metrics) and the [rest](/configuration/backends/rest.md) provider.
|
||||
|
