# Get Customer



## OpenAPI

````yaml openapi/yuno_sandbox_tested.json GET /v1/customers/{customer_id}
openapi: 3.1.0
info:
  title: Yuno Payments API
  version: 1.0.0
  description: >
    The Yuno Payments API is built around REST principles, using standard HTTP
    methods and JSON payloads.


    ## Authentication

    All requests require two headers:

    ```

    public-api-key: YOUR_PUBLIC_KEY

    private-secret-key: YOUR_PRIVATE_KEY

    ```


    ## Idempotency

    Payment mutations (create, capture, cancel, refund, payout) require an
    `X-Idempotency-Key` header (UUID).

    The API stores the key and returns the same response for duplicate requests
    within 24 hours.
