Master Data allows users to store and manage data in a structured manner. To abstract this kind of organization, the Master Data API is divided in two categories: Data Plane and Control Plane. The Data Plane is where the management of records happen, including searches and accessing Documents. The Control Plane is where the structure of both the records and the access to them is defined.

The Data Plane is the category to store and retrieve Documents. The Data Plane has a higher access volume to provide the necessary data to the stores, so the access to the Data Plane happens quickly and is highly available.

The /documents API can be used to store and retrieve Documents. In case of retrieval, you must indicate the id Field of the desired Document. The id Field contains an unique identifier of the Document.

In many cases, the user doesn’t know the id Field of a Document, but it can be found through a search using other Fields (i.e.: the name of a client). The /search and /scroll APIs can be used to find documents by Fields that are Searchable or Index.

Searchable is a Field configuration which enables the Field to be used in the /scroll API. At Master Data V1 is the property Is Filter whereas Master Data V2 is the property v-indexed.

An Index is a configuration which enables a shortcut to retrieve Documents faster and to guarantee uniqueness.

The Control Plane is the category that lets you manage how Data Plane behaves. Users can configure validation, search and triggers to Data Entities. Since the Control Plane only deals with the structure, and not the records themselves, access to the Control Plane happens less frequently than to the Data Plane.

Master Data V1 does not have a Control Plane API. All configuration is handled by the Admin through the Dynamic Storage, which can be accessed using the link https://{{account}}.ds.vtexcrm.com.br.

Master Data V2 has the /schema and /indices APIs and allows users to create and update JSON Schemas to any Data Entity at Master Data V2.

Creating and updating JSON Schemas changes the Data Plane behavior. JSON Schemas only exist in Master Data V2.

The endpoints in the Master Data API are:

• Schemas: Allows to create and read Schemas for a Data Entity. The use of Schemas enables searches with custom Fields and to add rules when managing Documents. More information about Schemas can also be found in the article Schema Lifecycle.
• Indices: Indices are shortcuts to Documents that enable fast access using other Fields beyond the Document id. More information about Indices can be found in the article Components.
• Documents: This is the API to manage Documents directly, accessing them individually through their id.
• Search: Allows the retrieval of many Documents with a variety of parameters, including Schemas and indexed Fields.
• Scroll: Allows the retrieval of a very large amount of Documents.

The table below shows what endpoints belong to which category and Master Data version.
