https://api.fuul.xyz/api/v1/payouts/recipient-mappings
Creates email-to-address mappings for recipient resolution. Once a mapping is created, any pending movements for that email will be asynchronously resolved to the target address.
By default, if a mapping already exists for a given email, it is skipped and returns an "already_exists" status.
Set overwrite_existing to true to update existing mappings with a new target address.
The source_identifier is always treated as an email address.
