Enter gift details with iMIS REST API

I am reaching out to inquire about the functionality of the iMIS REST API in relation to gift (donation) creation.

Specifically, I would like to understand whether it is possible to create a new gift and simultaneously enter details information when using the API.

In iMIS, a gift item can be configured to "Allow purchaser to enter details" at the time of entry in RiSE.

When this option is enabled, a text area labeled "Details" is displayed for the user to input relevant information.

Could you confirm whether the iMIS REST API supports this capability?
If so, I would appreciate guidance on how to achieve this, particularly when posting a ComboOrder data request to create a gift record.

Your insights on this matter would be highly valuable.

Thank you for your time and assistance.
Best regards,
Moli.
