add_on_required

Feature requires purchasing an add-on package

HTTP status	402 Payment Required
Error code	add_on_required
Resolve action	purchase_add_on

What happened

The organization tried to use a feature beyond its plan’s included allowance — for example, creating an alert when all of the plan’s included alert slots are already in use.

The plan’s allowance can be extended by purchasing add-on packages: each Alerts Pack add-on increases the alert allowance by five.

How to fix

Purchase the required add-on via the platform UI’s , or call the add-on endpoint directly:

POST /v1/organizations/{org_id}/billing/addons
{
  "type": "monitor_pack",
  "quantity": 1
}

After the purchase succeeds, retry the original request.
