Customers without an override are charged your global developer fee and are not listed; a removed override is not listed. ## What this endpoint does Lists your customers that have a developer fee override — a custom fee, or waived when `override.transfer` is omitted — most recently updated first. Customers without an override are charged your global developer fee and are not listed; a removed override is not listed. ## When to use it Use it to see every customer whose developer fee differs from your global schedule without fetching each customer. Page with `cursor` and `limit`. ## Before you call Requires a secret API key with fee read access. Only customers owned by the same tenant account are returned. An invalid or stale `cursor` returns `400 invalid_cursor`. ## Money and balance effect This is a read-only request. It does not reserve, debit, credit, or settle money. ## States and completion The list reflects the overrides in effect 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](/console/developers.md) for the complete workflow. ## OpenAPI ````yaml /api-reference/openapi.json get /v1/developer-fees/customers openapi: 3.0.0 info: title: Wayex API description: >- Wayex APIs for direct customer payment routes and isolated, prefunded Treasury accounts.
