# Service type and categories

> System-defined IDs for all service types, categories, and subcategories.

Every KarmaCheck service belongs to a type and a category.

## Type

The following table lists the possible types of services. The service type and its ID appear respectively as `serviceTypeName` and `serviceTypeId` in the response body of API endpoints like [`GET /case/id/{caseId}/services/{serviceType}`](/api-reference/cases/get-services-for-case). The ID is also accepted in the path parameter of endpoints like [`GET /case/id/{caseId}/data/{serviceTypeId}`](/api-reference/cases/get-case-data-by-case-id).

| Service type            | ID                                   |
| ----------------------- | ------------------------------------ |
| **Screening**           | 30bc2c03-c8dd-409a-8da6-e0070ea6a681 |
| **Legal**               | a3b74b1b-b665-40be-bad2-2a49c801cf3f |
| **Payment**             | service-type-payment                 |
| **Identity**            | service-type-idv                     |

| **Document Processing** | service-type-document-processing     |

## Category

The following table lists the possible categories that a service can belong to. The service category and its ID appear respectively as `serviceCategory` and `serviceCategoryId` in the response body of API endpoints like [`GET /case/id/{caseId}/services/{serviceType}`](/api-reference/cases/get-services-for-case).

| Service category                  | ID                       |
| --------------------------------- | ------------------------ |
| **Identity Verification**         | service-cat-idv          |
| **Criminal Check**                | service-cat-criminal     |
| **Motor Vehicle Record Check**    | service-cat-mvr          |

| **Occupational Health Screening** | service-cat-ohs          |
| **Professional License**          | service-cat-pro-lic      |

## Subcategory

Services under the Occupational Health Screening (OHS) category are further categorized by a subcategory. The following table lists the possible subcategories that an OHS service can belong to. The service subcategory and its ID appear respectively as `serviceSubCategory` and `serviceSubCategoryId` in the response body of API endpoints like [`GET /case/id/{caseId}/services/{serviceType}`](/api-reference/cases/get-services-for-case).

| Service subcategory | ID                      |
| ------------------- | ----------------------- |
| **Physical**        | service-subcat-physical |
| **Drug Screening**  | service-subcat-drug     |
| **TB**              | service-subcat-tb       |
| **Titer**           | service-subcat-titer    |
