Introducing GROQ-powered Webhooks


Everything in the Studio starts with the document. A document is what you create and edit in the studio—all the other types you may define live inside the documents. In the default studio configuration, the document-types are the ones that will be listed in the content-column.


  • REQUIREDtypestring

    Value must be set to document.

  • liveEditboolean

    Turns off drafts when set to true.

  • orderingsarray

    A declaration of possible ways to order documents of this type, documented here.

  • REQUIREDfieldsarray

    The fields of this object. At least one field is required. Documented here.

  • fieldsetsarray

    A list of fieldsets that fields may belong to. Documented here.

  • previewobject

    Use this to implement an override for the default preview for this type. Documentation here.

  • initialValueDocumentOrResolverFunction

    The initial value that will be used for all new documents created from this document type. Can be either a literal document value or a function that returns either a literal value or a promise that resolves to a document value.

At its core, a document is a JSON-object that has a unique _id, timestamps (_createdAt_updatedAt) and revision-marker _rev.

The document type is used to define the structure of a document that can be stored in our data store. You can think of a document as an object that, in addition to the fields you define, also has a unique id, (_id), a field for tracking created time and last updated time (_createdAt and _updatedAt) and a revision marker (_rev). Only documents can be referred to from other documents or retrieved by id and only document types will listed and creatable in the studio.

Apart from the above, documents are defined just like regular objects, so see the documentation of the object type for more info about how to define documents.
