[Table 1. Default Custom Connector Gateway schema fields]

{#custom-connector-gateway-default-schema-fields__table_ic1_2f5_hkc}

All fields in the Custom Connector Gateway schema are optional and can be fed selectively. Your custom connector doesn't have to populate every field when submitting ADDDOCUMENT or TOUCHDOCUMENT requests to the API endpoint on the
ingest gateway host. The only fields required in the request payload are the title and url fields from the parent schema. Include only the Custom Connector Gateway schema fields you actually
need to add or update.  
Note:  
All Custom Connector Gateway external content connectors on your instance share a single schema. When making changes to the Custom Connector Gateway schema for a new connector, check that those changes don't affect the behavior of your existing Custom Connector Gateway connectors.
