GET
Get a customer's developer fee

What this endpoint does

Returns the developer fee override for one of your customers, or override: null when the customer is charged your global developer fee.

When to use it

Use it to display or verify which developer fee a specific customer is charged.

Before you call

Requires a secret API key with fee read access and a customer ID owned by the same tenant account. A customer that belongs to another account returns 404.

Money and balance effect

This is a read-only request. It does not reserve, debit, credit, or settle money.

States and completion

The response is the effective override at read time. It does not reprice transfers already in progress.

Safe retries

GET requests are read-only and may be retried with normal exponential backoff. Do not send an Idempotency-Key. Read Developer settings for the complete workflow.
