Lets you add transactions of loyalty, non-loyalty, or not-interested customers. You can add batch transactions by passing each transaction details in a separate transaction attribute.

[!IMPORTANT] A successful API response (status code 200) only confirms that the transaction was created. Points accrual and promotion triggering depend on active loyalty program rules, store attribution (using the X-CAP-API-ATTRIBUTION-ENTITY-CODE header), product eligibility, and customer tier. If no rules match, the transaction may not reflect points or rewards in Member Care. Always review your loyalty program rules and product eligibility to ensure expected outcomes.

[!CAUTION] The transaction/add API processes one request per customer at a time. If two requests for the same customer are submitted simultaneously, one succeeds and the other is rejected with warning code 521 ("Multiple actions running for the same customer"). The retry mechanism is hardcoded and cannot be adjusted. To prevent this in bulk submission scenarios, send transactions for the same customer sequentially, not in parallel. If a 521 is returned, wait briefly and resubmit the failed transaction.

Currently, there is no validation that bill amount should match with sum of line items as the data is accepted as it is from POS or integration

Following are the key functionalities of the transaction/add API.

Registers customers automatically when a new identifier is passed with the transaction details.
If any identifier matches with another accounts, customer accounts will be merged if the config mentioned below is not enabled.
If CONFIG_SKIP_SECONDARY_ID_ON_PRIMARY_MISMATCH is enabled, if the primary identifier is different but any of the secondary identifiers exist, a new customer is registered with the primary identifier ignoring the secondary identifier. The config is available on the Registration Page of InTouch Profile > Organization Settings > Miscellaneous.
Also, this config overrides CONF_PRIMARY_IDENTIFIER_STRICT_CHECK.
Updates customer details if a registered identifier is passed with different customer details (other than customer identifiers).
Supports transactions with Product Variant and Product Bundle details.
Adds product variant to the database when a new variant product is passed with an existing base product.
Adds base product to the database when a new base product/variant product is passed. However, if a new base product is passed with variant details, it adds only base product and ignores variant.
For Multi Loyalty Programs, points can be grouped by their respective program IDs and correctly reflected in the side effects section of the response. To enable this, raise a JIRA ticket with the Sustenance team to activate the configuration CONF_ENABLE_GROUP_POINTS_BY_PROGRAM for your org.

Redeeming cart promotions for transactions

To redeem a cart promotion for a transaction made using v1 transaction API, use the Redeem Cart Promotion API after you evaluate and add the transaction for a customer. To apply and redeem the cart promotion while making a transaction, use the Transaction V2 API. With this API, you can add a transaction, apply, and redeem a cart promotion in a single call.

Note
Negative values for the transaction values such as amount, discount will not be considered.
