# Create Guardian Relation

> Link a parent (guardian) subscriber to a child subscriber so the parent can supervise the child's communications.

**Prerequisites:**
- Bearer token — `POST /v1.0/oauth2/tokens`
- Both subscribers must exist (`TSUID-`) — `POST /v1.0/subscribers/create`
- AI Guardian must be enabled on both subscribers — `POST /v1.0/subscribers/guardian-features`

**What this does:** Creates a one-way parent-to-child link. The parent gains the ability to receive filter notifications, manage filters on behalf of the child, and use age-preset modes (`CHILD`, `TEENAGER`, `ADOLESCENT`) on the child's call filters.

**Next steps:**
- Verify the link — `GET /v1.0/subscribers/guardians/relation/parent` (lookup by parent) or `GET /v1.0/subscribers/guardians/relation/child` (lookup by child)
- Create message and call filters on the child — `POST /v1.0/subscribers/message-filter`, `POST /v1.0/subscribers/call-filter`
- Remove the link later — `POST /v1.0/subscribers/guardians/relation/delete`
