Application Access is a feature that allows you to control the access level of other application scopes to your application’s data tables. You can use Application Access to control the following database operations:

• Create: This operation allows the user to create new records on the table. You can enable or disable this operation by selecting or clearing the Can create option.
• Delete: This operation allows the user to delete existing records on the table. You can enable or disable this operation by selecting or clearing the Can delete option.
• Read: This operation allows the user to view the records on the table. You can enable or disable this operation by selecting or clearing the Can read option.
• Write: This operation allows the user to modify the records on the table. You can enable or disable this operation by selecting or clearing the Can write option.

The one database operation that cannot be controlled with Application Access is Query. Query is not an operation, but a method of the GlideRecord class that is used to retrieve records from the database on the server-side. Query is not part of the Application Access rules, but it is affected by the Access Controls and the user’s roles.

One of the uses of the ServiceNow REST API Explorer is to create sample code for sending REST requests to ServiceNow. The REST API Explorer is a tool that allows you to discover and test the ServiceNow REST APIs. You can select an API endpoint, set the HTTP method, parameters, headers, and body, and then execute the request. The REST API Explorer will show you the response status, headers, and body, as well as generate sample code for various languages and frameworks, such as cURL, Java, JavaScript, Node.js, Python, Ruby, and more.
