Difference between Open Interface and API in Oracle Apps

Open Interfaces-

• In EBS one Open Interface may run many API calls.
• Open Interface run asynchronously.
• The good is that if there is failure of record, they remain in the table until either fixed or purged.
• They automate the interface into the APIs.
• This requires less work and less code as few SQL DML would simply .

APIs-

• When there is no corresponding Open Interface.
• Normally all Oracle APIs run synchronously, and provide immediate responses, therefore machism to be provided to handle such situation.
• That requires custom error handling routine.
• This may requires lot more effort as these need fine grain control approach.
