# List and create target groups for a customer

As a Reseller you can list and create target groups (user groups used for campaigns and training) for a customer. Get the customer's Company ID, then call the target-groups endpoints with **`X-KEEPNET-Company-Id`** so groups are scoped to that company. Use a credential with Client Role = **Reseller**.

***

## POST /api/companies/search

Get the customer's Company ID. Use the `resourceId` of the desired company in the next steps.

> Retrieves a paginated list of all companies you manage with license details. Each item includes `resourceId` — use it as the Company ID for scoped requests. **Test it:** Authorize with Client ID/Secret, then Send — request body is pre-filled.

{% openapi src="/files/YqgEnchxXuSVklhH9GGT" path="/api/companies/search" method="post" expanded="true" %}
[keepnet-api-spec.json](https://3453589210-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-LMcQ_WCXOrHv3r05ae5%2Fuploads%2Fgit-blob-31c738c1a6bb3d2911bd3730c780d6ad7fa6bbad%2Fkeepnet-api-spec.json?alt=media)
{% endopenapi %}

From the response, pick the company and note its `resourceId`. Example: `"resourceId": "xC5kfGz7w2Nz"` → use as `X-KEEPNET-Company-Id` in the target-group requests below.

***

## GET /api/target-groups

Returns all target groups for that customer (no pagination). Send **`X-KEEPNET-Company-Id`**.

> Retrieves a list of target groups. As a Reseller, send **`X-KEEPNET-Company-Id: <companyResourceId>`**.

## POST /api/target-groups/search

Returns a paginated, filterable list of target groups for that customer. Send **`X-KEEPNET-Company-Id`**.

> Returns a list of target groups. As a Reseller, send **`X-KEEPNET-Company-Id: <companyResourceId>`**. Request body: optional `filter`, `pageNumber`, `pageSize`, `orderBy`, `ascending`. **Test it:** Endpoints → **TargetGroup** — use dummy data (H8d) and set the header to a Company ID from companies/search.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.keepnetlabs.com/api-reference/reseller/users-and-groups/list-and-create-target-groups-for-customer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
