# POST /v1/contactGroups

`POST /v1/contactGroups`

Create a new contact group owned by the authenticated user. Created contact group names must be unique to the users contact groups. Attempting to create a group with a duplicate name will return a HTTP 409 error. Mutate requests for the same user should be sent sequentially to avoid increased latency and failures.

## Request body

  - `readGroupFields` string, google-fieldmask — Optional. A field mask to restrict which fields on the group are returned. Defaults to `metadata`, `groupType`, and `name` if not set or set to empty. Valid fields are: * clientData * groupType * metadata * name
