# ACH Blocks

Use these endpoints to view and manage the ACH receiving blocks on a Pocket. A block returns incoming ACH entries in one direction, `DEBIT` or `CREDIT`, unless one of its filters admits the originator. A filter admits one originator by its Company ID, optionally up to a maximum amount.
Blocks can be registered only on Pockets of business Customers, in either direction. A request for any other Customer is rejected with a `422`.
Only active blocks and filters are returned. A block or filter that has been removed, or does not exist, returns `404`. Removing a block also removes its filters.
A filter's maximum amount and label cannot be changed. To change them, remove the filter and add a new one for the same Company ID. Between the two calls, that originator's entries are refused.
ACH blocks aren't available by default and must be enabled; contact your Jiko point of contact to learn more. Requests made without them enabled are rejected with a `403`.
