Salesforce Fields

Use these topics to learn how the API represents field values, which fields you set, and which fields Salesforce maintains for you.

• Primitive Data Types - Identify the base types the API uses for field values, such as string, date, and int.

• Field Types - See the field types built on those primitives, such as currency, picklist, and formula.

• Field and Type Differences in Salesforce Apps and APIs - Compare a field’s name in a Salesforce app with its API data type when the names differ.

• API Field Properties - Check which operations a field supports, such as create, update, and filter.

• Required Fields - Find the fields that must have a value when you create or update a record.

• System Fields - Review the read-only fields Salesforce sets for you, such as Id and LastModifiedDate.

• Frequently Occurring Fields - Look up fields that appear on many objects, such as OwnerId, RecordTypeId, and CurrencyIsoCode.

• Custom Fields - Learn how to read and write custom fields that your admin adds to an object.

• Compound Fields - Work with an address or a geolocation as one structured field.
