# Start Plaid Link to connect a new bank login for a family person, or to add accounts to or reconnect an existing one

`POST /families/{id}/accounts/link-token`

## Request

- Base URL: `https://ledgerhq.pro/api/v1`
- URL: `https://ledgerhq.pro/api/v1/families/{id}/accounts/link-token`
- Auth: one of:
  - HTTP bearer and API key in header `x-organization-id`
  - HTTP bearer and API key in header `x-organization-id`

Firm-side family relationships only. Select the firm with x-organization-id. Owners, Admins and Staff Admins access all firm families; Staff Members need independent family assignment. Company access does not grant family access. OAuth requires the broad mcp grant, not a narrow banking scope; API keys retain ordinary agent permission scopes. No accounting organizations, portal grants, invitations or charges are created. Writes require ordinary firm write entitlement. Cross-firm and inaccessible IDs return 404. Plaid Link runs in the browser: request a link token, open Plaid Link with it, then send the result to link-complete. Requires banking permission.

## Path parameters

- `id` string, uuid, required
