# Get source definition spec

Retrieve the JSON schema specification for a source definition, describing the configuration fields needed to set up a connector of this type.

Returns the configuration specification (JSON schema) for a given source definition. Use this to dynamically render configuration forms or validate source configuration before creating a source.

#### Path Parameters

**`organization_id`** string required

The unique identifier of the organization (format: `org_*`).

**`definition_id`** string required

The source definition ID to retrieve the spec for.

## Returns

A specification object containing `connection_specification` (JSON schema describing the required and optional configuration fields), along with metadata such as `documentation_url` and `supported_destination_sync_modes`.
