### Description{% #description %}

This check ensures that the `minimum_compression_size` attribute is set to a value greater than -1 and less than 10485760 for the `aws_api_gateway_rest_api` resource, enabling proper payload compression. Without valid configuration, API data transfer can be inefficient, leading to increased bandwidth costs and a slower experience for API consumers. Setting a secure configuration, such as shown below, ensures that response payloads are compressed appropriately, improving performance and security by preventing the misuse or neglect of compression settings.

```
resource "aws_api_gateway_rest_api" "example" {
  name = "regional-example"

  endpoint_configuration {
    types = ["REGIONAL"]
  }

  minimum_compression_size = 0
}
```

## Compliant Code Examples{% #compliant-code-examples %}

```terraform
resource "aws_api_gateway_rest_api" "negative1" {
  name = "regional-example"

  endpoint_configuration {
    types = ["REGIONAL"]
  }

  minimum_compression_size = 0
}
```

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```terraform
resource "aws_api_gateway_rest_api" "positive1" {
  name = "regional-example"

  endpoint_configuration {
    types = ["REGIONAL"]
  }
}


resource "aws_api_gateway_rest_api" "positive2" {
  name = "regional-example"

  endpoint_configuration {
    types = ["REGIONAL"]
  }

  minimum_compression_size = -1
}


resource "aws_api_gateway_rest_api" "positive3" {
  name = "regional-example"

  endpoint_configuration {
    types = ["REGIONAL"]
  }

  minimum_compression_size = 10485760
}
```
