Follow the steps below to build a gift card integration with the Toast platform.
This integration allows customers to use your gift card functionality in their Toast POS workflows.
Review and implement the instructions in How to build a Toast integration.
Your gift card integration requires a single endpoint. Submit your test environment endpoint to Toast support so they can set up the endpoint in the sandbox environment.
Review the gift card integration overview to understand the flow of information in a gift card integration.
In addition, familiarize yourself with physical card requirements and workflows that involve multiple transactions.
Use the integration verification tool to send a Get Balance request to your endpoint.
Review the structure, format, and headers of this request to familiarize yourself with gift card requests in Toast.
If your integration will support physical gift cards, you must select a card vendor.
When restaurants purchase new physical cards, they should import the card numbers into your platform so that you recognize those card numbers when you receive gift card transactions from them.
For more information, see Physical gift card requirements.
When you receive a GIFTCARD_GET_BALANCE request, you
should return the balance of this card and a 200 HTTP response status
code.
Review all gift card transaction types and determine which of the following transaction types you will support:
-
GIFTCARD_ACTIVATE -
GIFTCARD_ADD_VALUE -
GIFTCARD_REDEEM
Toast support recommends that you support all of these transaction
types. For each transaction type that you support, develop successful
responses that contain a 200 HTTP response status code and a
transactionStatus of ACCEPT.
For transaction types that you do not support, your endpoint must
return a 400 HTTP response status code and a
transactionStatus of
ERROR_TOAST_TRANSACTION_TYPE_NOT_SUPPORTED.
The following transactions can be reversed through a
GIFTCARD_REVERSE request:
-
GIFTCARD_ACTIVATE -
GIFTCARD_ADD_VALUE -
GIFTCARD_REDEEM
When you receive a GIFTCARD_REVERSE request, you must
reverse the transaction whose Toast-Transaction-GUID is in
the previousTransaction value.
Ensure that your endpoint is idempotent using the
Toast-Transaction-GUID header on the transactions you
receive.
If two requests contain the same
Toast-Transaction-GUID, they are the same request.
Ensure that your endpoint adheres to Toast gift card latency requirements. This allows the Toast platform to correctly understand how you processed the transaction in your system.
If your endpoint does not adhere to timeout requirements, guests will see an error message on the POS app that instructs them to contact your support team.
Your system must maintain an allowlist of restaurant GUIDs that your integration recognizes.
If the Toast-Restaurant-External-ID header in a gift
card transaction contains a restaurant GUID that is not on your
allowlist, your endpoint must return a 400 HTTP response status code and
a transactionStatus of
ERROR_INVALID_RESTAURANT.
Your endpoint must validate that gift card transactions came from the Toast production environment.
If your gift card
authentication process determined that a transaction came from
somewhere other than the Toast production environment, your endpoint
must return a 400 HTTP response status code and a
transactionStatus of
ERROR_INVALID_TOKEN.
Use the integration verification tool to test authentication against your production endpoint, because this tool submits requests out of the Toast sandbox environment.
If you receive a gift card transaction whose
giftCardIdentifier you do not recognize, your endpoint must
return a 400 HTTP response status code and a
transactionStatus of
ERROR_CARD_INVALID.
If you receive a GIFTCARD_ACTIVATE transaction for a
card that is already active, your endpoint must return a 400 HTTP
response status code and a transactionStatus of
ERROR_CARD_ALREADY_ACTIVATED.
If you receive unexpected information from the Toast platform,
your endpoint must return a 400 HTTP response status code and one of the
following values for transactionStatus, depending on the
information you receive:
-
ERROR_INVALID_TOAST_TRANSACTION_TYPE -
ERROR_INVALID_INPUT_PROPERTIES -
ERROR_TRANSACTION_DOES_NOT_EXIST -
ERROR_TRANSACTION_CANNOT_BE_REVERSED
See Response status types for more information.
Use the gift card integration test plan to validate that you correctly handle each test case.
To ensure that your endpoint can handle a high volume of gift card transactions at a time, add 10+ gift cards to a POS order to ensure that your endpoint can handle this volume.
Consider any additional load-test workflows you should validate before going live.
Contact the Toast support team about walking through the test plan together.
After the Toast team confirms that your integration is ready to go live, send your production endpoint to the Toast support team.
Set up the allowlist of restaurant GUIDs you support and prepare a sample email for requesting new integration connections.
The Toast support team will supply you with a guide for integration enablement.

After you build your core gift card functionality, create reports that restaurants can use to understand gift card cash flow.
Here are some ideas for information to report on over time:
- Sales
-
-
Number of gift cards sold
-
Currency value of gift cards sold
-
Average value of gift card sold
-
- Redemptions
-
-
Number of gift cards fully redeemed
-
Currency value of gift card redemptions
-
- Balances
-
-
Average balance on active cards
-
- Escheatment
-
-
Number of gift cards that expired
-
Average value of expired gift cards
-
- Cash-outs
-
-
Total currency value of cash-out transactions
