When the customer purchases a product that is not yet available, you can request two authorizations and a capture. You will first request an authorization to ensure that funds are available, and then you ship the available products. After the remaining products become available, you will request follow-on authorization to ensure funds are still available. You will ship the remaining products, and request a capture.
Cybersource
 links the follow-on authorization to the first authorization and the capture request to the other transactions.
Step 1: Requesting an authorization
You will request an authorization to ensure that funds are available for one or more of the products that are available for immediate shipment. The authorization request requires no additional fields or requirements than a basic authorization.
Step 2: Requesting a follow-on authorization
After the product becomes available, you request a follow-on authorization to ensure that funds are still available. The follow-on authorization request must include the link-to-request field in addition to the basic fields required for every authorization request. The link-to-request field in an authorization request triggers the split-shipment functionality.
Set the link-to-request field to the request ID from the value returned in the endpoint.
Field specific to requesting a follow-on authorization request:
First Authorization Response: The value is returned in the endpoint.
Follow-on Authorization Request:

 attempts to link the follow-on authorization request to the first authorization
  • If the link-to-request value is valid, the follow-on authorization is linked to the original authorization in the Business Center and in reports.
  • If the link-to-request value is not valid, the follow-on authorization is not linked to the original authorization in the Business Center and in reports.
Step 4: Requesting a capture
You ship the product and request a capture. The capture request requires only the basic fields as any capture request.
Step 5:
Cybersource
 attempts to link the capture request to the other transactions
  • If the link-to-request value for the capture is valid, all three transactions (first authorization, follow-on authorization, capture) are linked together in the Business Center and in reports.
  • If the link-to-request value for the capture is not valid, the follow-on authorization and capture are linked to each other in the Business Center and in reports, but they are not linked to the first authorization.
