True or False? A field that is required or read-only on a page layout can be accessed through the API.

1. True

2. False

3. Only if the field is not required

4. Only for custom objects

The correct answer is: True

A field that is marked as required or read-only on a page layout can indeed be accessed through the API. The designations for fields in a page layout are primarily about how users interact with them in the user interface. However, when it comes to API access, the rules are different. The Salesforce API is designed to accommodate various operations regardless of the user interface constraints. Therefore, even if a field is required or read-only on a layout, external applications or integrations connecting through the API can still access that field. This includes reading its value or updating it, provided the user or integration has the necessary permissions and access controls in place. Thus, the assertion that a field can be accessed through the API, regardless of its status on the page layout, is correct. This distinction is crucial for developers and system integrators who may need to manipulate or pull data programmatically without being hindered by the limitations set in the Salesforce user interface.
