Cloud Notification Service has the following limits:
- Quotas are organizational constraints that our support team can change upon request.
- Limits are technical constraints of the Yandex Cloud architecture. You cannot change the limits.
If you need more resources, you can increase your quotas in one of the following ways:
- Make a request to increase your quotas.
- Contact support and tell us which quotas you want to increase and by how much.
To have your request processed, you must have the quota-manager.requestOperator role or higher, e.g.,editor or admin.
You can manage quotas using Cloud Quota Manager.
