Scripted REST API vs Flow Designer - Which is better to handle large volume transactions

[harikumar2]

I would like to get your feedback on the most effective approach for managing anticipated high volume of transactions in ServiceNow, specifically with the expectation of around 1 million transactions per day from our SAP system.

We have two options to consider:

1. Scripted REST API using Import Set API
2. Flow Designer with flow executions turned off, capturing logs as scripts

Please share your insights on which option you believe would be more effective for handling this large volume of transactions and ensuring scalability.

Hi @harikumar2 

For large-volume transactions, Scripted REST API is generally the better choice due to its flexibility, performance, and scalability.
