Are CRUD operations supported on custom records using netsuite standard rest api web services?

AI generated answer (using internal Slack threads):

Yes, CRUD operations are supported on custom records using NetSuite's standard REST API web services. However, there are some limitations and prerequisites to consider. Firstly, you need to enable the REST Record Service (Beta) feature in Setup > Company > Enable Features to work with this record. This feature is still in beta, so it's important to understand that it may not be fully functional or stable. Secondly, not all records are supported for CRUD operations via REST API. You can refer to the SuiteCloud Supported Records documentation for a list of supported records. Lastly, when querying custom records, you can use record collection filtering to pull a customer record where a custom field value is equal to a specific value. Please note that while it's theoretically possible to achieve CRUD operations via Suitelets, this is not the preferred method for serious integrators. Suitelets would need to be made externally available, which essentially means public access, and this may not be desirable for security reasons. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
