# Clear Response Enrichment

For transactions where MRS is unable to identify the merchant there is an option to clean the merchant description and categorise the transaction.

* Consider this a “backup” option for when MRS is unable to identify a merchant.
* It provides some “cleaning” of the Merchant Description when a match is not found.

<table><thead><tr><th width="443">Example input merchant description</th><th>Example cleaned result</th></tr></thead><tbody><tr><td>JOHN’S BOAT HOUSE 5671121110</td><td>John’s Boat House</td></tr><tr><td>#SNOWDROP#RESTAURANT#AND#POOL#HALL#</td><td>Snowdrop Restaurant And Pool Hall</td></tr></tbody></table>

* When an MCC Code is provided in the request then the response will also include Categorisation.&#x20;
* This means that a transaction can be categorised even in cases where the Merchant was not identified.&#x20;

### ClearResponse

We use the parameter `clearResponse` and show the `isclearResponse` field in the response to show the above behavior.

**Input Parameter**

`clearResponse` is an optional parameter. If this is set to `true`, even if we cannot find the merchant, we will attempt to clean up the transaction/add categorization as above.  This is set to `true` by default.

**Response Field**

For MRS Responses where we did not find a merchant, but were still cleaned up in this way, will have the `isClearResponse` flag set to `true` in the response.
