# Overview

# Connector Schema service overview

The Connector Schema service returns the schema for a Notification Center connector of a given type (for example, Slack, generic HTTPS, or PagerDuty). The response contains both `connector_config_schema` — the fields needed to configure the connector itself — and one or more `message_config_schemas`, which define the preset (message) fields for that connector type. Each schema lists every field's name, type, allowed values, and whether it is required. Check `connector_config_schema` before creating a connector and `message_config_schemas` before creating a preset.
