# Refund API

#### 1. Transactions that are NOT supported by the Refund API

1. Transactions that are marked as failed on Coda records but customers are charged 
2. Codashop transactions

#### 2. What is the date range limitation of the refund?

#### 3. What is the SLA between the initiated refund request and the updated final refund status?

Within <mark style="color:purple;">**3 working days**</mark>

#### 4. What is "`amount_currency`" and "`amount_value`" ?

The local currency based on the original payment

#### 5. What payment channels are eligible for a refund?

Please refer to the list [**here**](https://coda-payments.gitbook.io/coda-private-technical-documentation/codapay/refund-a-payment/supported-payment-channel). If the payment channel is not supported, we will return with "<mark style="color:purple;">**Failed**</mark>" status. Please reach out to publisher support if you have any concerns.

#### 6. Do we support Sandbox testing?

Yes. However, to simulate approval or rejection of a refund request, merchants must provide the **Coda transaction ID** to us. Coda will then manually update the status.
