A developer is creating an API for a custom table that tracks service orders. External systems need to mark a service order as 'started' by calling an API endpoint. The action must be performed on a specific service order record. What should the developer implement?

A custom API page that exposes the Status field as editable.

A codeunit with a procedure that updates the status, exposed as a web service.

An OData bound action on the service order API page that updates the Status field.

An OData unbound action that takes the service order number as a parameter and updates the status.

A partner is developing an API for Business Central online and wants to ensure that only authorized external applications can access it. The API will be used by a custom mobile app. Which configuration should the developer implement?

Enable the 'Require API Key' option in the API setup.

Use a web service access key that is shared with the mobile app.

Set the API page's Access property to 'Internal' to restrict access.

Register the API in Azure AD and require OAuth 2.0 authentication for the app.

A company has a Business Central online environment with a large number of read-only API calls from a business intelligence tool. The calls are causing performance issues on the primary database. The developer wants to offload these reads to a secondary replica. What should the developer do?

Set the DataAccessIntent property to ReadOnly on the API pages used by the BI tool.

Create a new API page that uses a read-only table and expose that to the BI tool.

Enable the 'Read Replica' option in the Business Central admin center.

Use a query object instead of an API page for the BI tool.
