API: Selecting Specific Fields
When you hit an endpoint, a range of default fields are automatically returned. If you want something that isn't default, or you want to return less data to speed things up, you can pick the fields to be returned. In the case of referrals or clients you can also return any single record extension databases. Use /field/ with semicolon separated field names to choose the fields you want to return.

The API can tell you which fields are available by appending /selectable_fields to the group.

IDs or names?
For read-only applications, e.g. a reporting dashboard, it may be useful to ask the API for the names of options, instead of the IDs, e.g. "Private Rented" instead of "4" for accommodation. The is referred to as "resolving" the IDs. You can specify individual fields, like this:
```v2/clients/id/1/field/id;ethnicity;main_language;school/?resolveIds[]=ethnicity&resolveIds[]=main_language```
or all fields, like this:
```v2/clients/id/1/field/id;ethnicity;main_language;school/?resolveIds[]=ALL```
NB this only applies when GETing data, records must always be created and updated using IDs.
