Processing Two Authorizations and a Capture for Multiple Products {#payments-processing-basic-split-ship-two-auth-cap-intro}
============================================================================================================================

When the customer purchases a product that is not yet available, you can request two authorizations and a capture. First request an authorization to ensure that funds are available, and then ship the available products. After the remaining products become available, request follow-on authorization to ensure funds are still available. 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**  
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, request a follow-on authorization to ensure that funds are still available. The follow-on authorization request must include the processingInformation.linkId field in addition to the basic fields required for every authorization request. The processingInformation.linkId field in an authorization request triggers the split shipment functionality.  
Set the processingInformation.linkId field to the {id} value from the endpoint.  
**Field specific to requesting a follow-on authorization request:**  
First Authorization Response: The {id} value is returned in the endpoint.  
Follow-on Authorization Request: `processingInformation.linkId=SWVdPS5IM`  
**Step 3: `Cybersource` attempts to link the follow-on authorization request to the first authorization**

* If the processingInformation.linkId value is valid, the follow-on authorization is linked to the original authorization in the `Business Center` and in reports.
* If the processingInformation.linkId 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**  
All three transactions (first authorization, follow-on authorization, capture) are linked together in the `Business Center` and in reports.
