# Configure default values

> Learn how to set default values writing to Salesforce.

## Overview

When Unify creates or updates records in Salesforce, it will populate each
Salesforce field using the value in the corresponding Unify field. However, you
can also specify *default values* to be used as a fallback. This can useful in a
few different scenarios:

1. You may have custom fields in Salesforce that require a value
2. You may want to write a custom value to a field that is not available in the
   field mappings
3. You may want to dynamically set a value in different Plays or Play actions

You can set global default values from [Settings → Integrations → Salesforce](https://app.unifygtm.com/dashboard/settings/integrations/salesforce).
These will be used for all writes to Salesforce unless overridden in a Play or
by a field mapping.
