Update Order

Purpose:

Updates order information before capture.

• Adding an external code that represents the order ID of the merchant if not already submitted previously.
• Changes the order amount associated with the order.

Preconditions:

• uuid of the order
• order is in state created and does not already has ane external_code for an update of 'external_code`
• order is in state created or partially_shipped for an update of the order amount

Success:

• Response Code: HTTP 204

Attention:

• The value provided under external_code (the order number from your backend) will be used by Billie in communication with the buyer after capture.
• If an external_code was provided at create order or confirm session call the uptade order call will fail, if it is a different external_code.
• Lowering the values under the amount object to equal the sum of all partial captures will result in the order state to transition from partially_shipped to shipped.
• If the update order call increases the amount of the order, the increased amount will be subject to all checks and validations as a newly created order.
• If any part of the update order call is failing, no changes to the original order will be applied.
