Schema & Types

The basic unit of components of a GraphQL schema are object types - it represents an object you can fetch for and the definitions of what fields will be included in the response. A representation of GraphQL schema language may look like this in Identity API:

type SyntheticDevice {
  tokenId: Int!
  integrationId: Int!
  address: Address!
  mintedAt: Time!
  • SyntheticDevice is a GraphQL Object Type, meaning it's a type with some fields. Most of the types in your schema will be object types.

  • tokenId, integrationId, address, and mintedAt are fields on the SyntheticDevice type. That means these 4 fields can appear in any part of a GraphQL query that operates on the SyntheticDevice type.

  • Int is one of the built-in scalar types - these are types that resolve to a single scalar object, and can't have sub-selections in the query.

  • Int! means that the field is non-nullable, meaning that the DIMO GraphQL service promises to always return a value when queried.

DIMO Check-in

🎉 At this point, you should feel comfortable in querying the DIMO Identity API in GraphQL. Try writing up your first query and sending it over to the API in the next section.
