Can we use Recurring Application Charge similar to appSubscriptionCreate in GraphQL to set 0 price

[Reymundo]

We are running in a scenario where we would like to create a Recurring Application Charge as a 0 with the idea to use later the UsageCharge where we can apply a fee per txn, and the existing Rest API RecurringApplicationCharge (shopify.dev) does not allow a price as a zero. However, if we use the GraphQL 

https://shopify.dev/docs/api/admin-graphql/2023-04/mutations/appSubscriptionCreate it allows us to set as a zero.

Do you know if there is an existing Rest API similar as the graphQL that allows us to set the price as zero?

Thanks

I found the answer, the problem with the current Rest API in my side it was that we need to use the capped_amount field instead of cappedAmount in camel case, this solved the problem
