# Set the developer fee schedule

> Replaces the developer fee schedule used for eligible future direct-route conversions.

## What this endpoint does

Replaces the developer fee schedule used for eligible future direct-route conversions.

## When to use it

Use it when changing the flat amount, basis-point amount, or removing the schedule.

## Before you call

Use a secret API key with fee-management access and send the complete desired schedule.

## Money and balance effect

This does not debit a wallet immediately. The new schedule affects eligible conversions created after the change.

## States and completion

A successful response confirms the saved schedule. In-flight transfers keep the pricing captured for them.

## 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 [Developer settings](/console/developers) for the complete workflow.
