# Detailed description

The AWS API supports Authorization parameters as GET parameters, e.g. here's a GET request to SendMessage on SQS:

```
curl 'http://localhost:4566/000000000000/SomeQueue.fifo?Action=SendMessage&MessageGroupId=Default&MessageDeduplicationId=1615597859837&MessageBody=%7B%22gateway_id%22%3A%20%2204e73c80-3539-499c-92a4-a0b106c2f6ab%22%7D&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=test%2F20210313%2Fus-east-1%2Fsqs%2Faws4_request&X-Amz-Date=20210313T011059Z&X-Amz-Expires=86400000&X-Amz-SignedHeaders=host&X-Amz-Signature=2c652c7bc9a3b75579db3d987d1e6dd056f0ac776c1e1d4ec91e2ce84e5ad3ae'
```

## Expected behavior

Should send the message and return receipt information.

## Actual behavior

Returns...

```
