# Client Groups

Rport client group can be created by:

adding single clients to it;
dynamic criteria using wildcards.

Managing client groups is done via the APIopen in new window. The /client-groups endpoints allow you to create, update, delete and list them.

As listed in the API docs Client Group is defined by:

id - unique group identifier
description - group description
params - parameters that define what clients belong to a current group. Each parameter can be specified by:
- exact match of the property (ignoring case). For example,
```
params: {
  "client_id": ["test-win2019-tk01", "qa-lin-ubuntu16"]
}
```

  Means only clients with id equals to test-win2019-tk01 or qa-lin-ubuntu16 belong to a current group.
- dynamic criteria using wildcards (ignoring case). For example,
```
params: {
  "os_family": ["linux*", "*win*"]
}
```

  Means all clients with os_family that starts with linux OR that contains win belong to a current group.
NOTE: if few different parameters are given then a client belongs to this group only if client properties match all the given group parameters. If client parameter has multiple values (like tags, ipv4, ipv6, etc) then he belongs to a group if at least one client param matches one of group parameters. For example,
```
  params: {
    "tag": ["QA", "my-tag*"],
    "os_family": ["linux*", "ubuntu*"]
  }
```

Means clients belong to this group only if both conditions are met:
1. has tag equals to QA OR tag that starts with my-tag;
2. its os_family starts with linux or ubuntu.
client_ids - read-only field that is populated with IDs of active clients that belong to this group.
