# Update tenant treasury settings

> Sets the tenant-wide payout remitter default: `wayex` shows “Wayex” as the remitter on AUD payouts, while `tenant` shows your onboarded company name. The choice is constrained to those two values — it is never free text.

## What this endpoint does

Sets the tenant-wide payout remitter default: `wayex` shows “Wayex” as the remitter on AUD payouts, while `tenant` shows your onboarded company name. The choice is constrained to those two values — it is never free text.

## When to use it

Set it during onboarding, or whenever you want subsequent payouts to default to a different remitter. Each payout request can still override the default per payout.

## Before you call

Use a secret API key with `treasury:write`. The onboarded company name used by the `tenant` option comes from your account profile and cannot be edited through this endpoint.

## Money and balance effect

This changes a resource or configuration but does not directly reserve, debit, credit, or settle wallet money.

## States and completion

The new default applies to payouts created after it is set; it does not change the remitter recorded on payouts already submitted.

## Safe retries

Send a unique `Idempotency-Key` for the logical action. If the response is lost, retry the same payload with the same key; never create a new key merely because the first response timed out.

Read [Beneficiaries and payouts](/treasury/beneficiaries-and-payouts) for the complete workflow.
