Actions
Understand Affirm's Transactions API actions.
Overview
After creating a transaction
, you can manage it through various states and integrate each of these actions into your order management system where you fulfill orders and/or process payments, refunds, and cancelations.
Read
With the Read Transaction API
, you can use the id
returned from the transaction
object to retrieve all checkout data and the transaction status associated with a specific transaction. Reading transaction information is useful for updating your records or order management system with the current state of a transaction before performing any actions on it. It can also keep your system in sync with Affirm if your staff is manually managing loans in the merchant dashboard.
You can read single or multiple transactions. Note that if you don't specify an id
, the response includes a list of transactions. You can define how the results are paginated using the limit
, before
, and after
query parameters.
// Read a single transaction
curl https://sandbox.affirm.com/api/v1/transactions/id
-X GET
-u "public_key:private_key"
// Read multiple transactions
curl https://sandbox.affirm.com/api/v1/transactions/?limit=5&before=1234-ABCD
-X GET
-u "public_key:private_key"
Void
Voiding an authorized transaction does the following:
- Permanently cancels a loan
- Notifies the user that the transaction was canceled
To cancel or delete an authorized transaction, use the id
associated with the transaction to void it. For example, this can occur when a user decides to cancel their order before it's fulfilled. Note that we can only void uncaptured loans.
curl https://sandbox.affirm.com/api/v1/transactions/id/void
-X POST
-u "(public_api_key):(private_api_key)"
Refund
Refund a transaction based on the original purchase, similar to refunding a credit card transaction. Affirm automatically calculates all interest and fees corresponding to the refunded amount.
Additionally, you can optionally refund part of a transaction by specifying an amount. For partial refunds, you can apply any amount of refunds so long as there is a positive balance on the loan.
Once a loan has been fully refunded, it can’t be reinstated. You can refund the customer using the Refund Transaction
request or the Merchant Portal.
curl https://sandbox.affirm.com/api/v1/transactions/id/refund
-X POST
-u "(public_api_key):(private_api_key)"
-H "Content-Type: application/json"
-d '{"amount": 50000}'
Update
Use the Update Transaction
request to update a transaction with new fulfillment or order information, such as shipping_confirmation
, shipping_carrier
, or order_id
. Settlement reports associate your internal order IDs with specific Affirm transactions.
curl https://sandbox.affirm.com/api/v1/transactions/id/update
-X POST
-u "(public_api_key):(private_api_key)"
-H "Content-Type: application/json"
-d '{"order_id": "JLKM4321", "shipping_carrier": "USPS", "shipping_confirmation": "1Z23223", "shipping": {"name":{ "full": "John Doe"},"address": {"line1": "325 Pacific Ave", "state": "CA", "city": "San Francisco", "zipcode": "94111", "country": "USA"}}}'
