I am having an issue calling External Transfer Settings API. I tested other APIs and was able to get a response. Below is the URI I used for External Transfers.
https://banno.com/a/transfer-settings/api/v0/institutions/xxxx/xxxxxxx/transfer/settings/external and the response I got is 'Cannot PUT /a/transfer-settings/api/v0/institutions/xxxx/xxxxx/transfer/settings/external'
