Update the maximum amount of a charge

You can update the maximum amount that can be charged to a merchant for each purchase using the appSubscriptionLineItemUpdate mutation. This mutation lets you update plans if you decide to change your business model.

If you try to create a usage record for a usage pricing plan with an amount less than the new usage record, then the request fails. You need to increase the cappedAmount, and then obtain merchant approval before you can create more usage records.
