# Set the call plan of a number

`PUT /numbers/{id}/call-plan`

## Request

- Base URL: `https://api.hypamoon.com/api/v1`
- URL: `https://api.hypamoon.com/api/v1/numbers/{id}/call-plan`
- Auth: one of:
  - HTTP bearer
  - OAuth 2 (authorization code, authorization URL `https://app.hypamoon.com/oauth/authorize`, token URL `https://api.hypamoon.com/oauth/token`, scopes: `numbers:write`)

Replaces the call plan of one number. A plan with an ai_agent node needs the assistant (PUT /assistant; voice AI is always included) and updates the assistant with this plan. Send If-Match with the ETag from GET to avoid overwriting a newer plan.

## Path parameters

- `id` string, uuid, required

## Headers

- `If-Match` string

## Request body

  - `entry` string, required: The id of the first node.
  - `nodes` object, required: The nodes by id. The key must be the same as the node's id.

## Response `200`
