 Sending and verifying a payload
===============================

There are cases in which you would like to send a payload and verify the response to determine if its services are up and active for example, if you need to determine if a down stream service is connected and functioning correctly.

To achieve this, you will need to manually update a few fields in the database and optionally create a custom response checker specifically for that monitor to verify the response from the uptime monitor request.

In this example, you will need to set the following fields in the database:

- `uptime_check_method`: `POST`
- `uptime_check_payload`: `{"foo":"bar"}`
- `uptime_check_additional_headers`: `{"Content-Type":"application/json"}`
- `uptime_check_response_checker`: `App\ResponseCheckers\ExampleChecker`

*More details on these fields can be found in the section "[Manually Modifying Monitors](/laravel-uptime-monitor/v3/advanced-usage/manually-modifying-monitors)"*

We will want to do some custom verification specifically for the response of this check.

Our checker could look something like the following:

```
