# Set Body Policy

The Set Body policy allows you to set or override the incoming request body.
[GET or HEAD requests do not support bodies on Zuplo](https://zuplo.com/docs/articles/zp-body-removed),
so be sure to use the
[Change Method](https://zuplo.com/docs/policies/change-method-inbound) policy to
update the method to a `POST` or whatever is appropriate. You might also need to
use the [Set Header](https://zuplo.com/docs/policies/set-headers-inbound) policy
to set a `content-type`.

## Configuration

The configuration shows how to configure the policy in the 'policies.json' document.

```json title="config/policies.json"
{
  "name": "my-set-body-inbound-policy",
  "policyType": "set-body-inbound",
  "handler": {
    "export": "SetBodyInboundPolicy",
    "module": "$import(@zuplo/runtime)",
    "options": {
      "body": "Hello World!"
    }
  }
}
```
