The add-in models SendGrid APIs as relational tables, views, and stored procedures. Most tables, views, and stored procedures are defined in schema files, which are simple, text-based configuration files.

However, the Recipients table is dynamic: The add-in connects to SendGrid and gets the metadata for this table by calling the appropriate Web services. Any changes you make to the custom filters you define for Recipients are available when you connect; you can use these custom filters as columns in the WHERE clause. These custom filters are surfaced in the CustomFields table.

API limitations and requirements are documented in this section; you can use the SupportEnhancedSQL feature, set by default, to circumvent most of these limitations.
