The No Cart feature allows transactions in collana pay to be processed without cart communication with the Payment Service Provider. This feature is particularly relevant when sales lines in Microsoft Dynamics 365 Business Central are changed retrospectively and the original cart can no longer be updated.
However, No Cart should only be used deliberately, as transparency and traceability are limited when using this function.
Typical use cases
- Bundles in the shop that are only resolved into individual set items in Business Central
- Subsequent replacement of items (e.g. different variants or substitute items)
- Payment Service Providers that technically do not support a Cart Update
- Transactions in a status where a Cart Update is no longer possible
In general, the Cart Update function should be used whenever possible. If this is not possible, No Cart provides an alternative solution.
Important limitations
- Cartless communication is not supported by all Payment Service Providers
- If there is an existing posted sales invoice, No Cart no longer works
- In the collana pay logs, carts may no longer be visible
- Historical cart information is only available in the original request
Activating No Cart
Step 1: Activation in COPAL
In COPAL, the function Disable Cart Validation must be enabled in the Advanced Options of the Provider Account.
Step 2: Activation in Business Central
In Business Central, there are two options:
- Globally for a payment method:
collana pay setup → Payment Methods → payment method card → enable No Cart
- For a single transaction:
collana pay transaction → enable No Cart
Behavior when changing sales lines
When No Cart is active, sales lines are changed and the order is released:
- A pop-up appears asking whether the lines should be updated
- After confirmation, the sales lines are transferred to the transaction card
- The order is released
The transaction then contains only the current sales lines.
- Individual lines may have different prices
- The Total Amount of all lines must exactly match the original transaction amount
- The total amount must not change
If the order should not yet be released, the button Recreate All Transaction Items can be used on the transaction card to write the sales lines to the transaction.
