Speckle Syntax Graphql

Quick Reference

GraphQL Endpoint

| Environment | URL | |-------------|-----| | Speckle Cloud | https://app.speckle.systems/graphql | | Self-hosted | https:///graphql |

ALWAYS send requests as HTTP POST with JSON body containing query, variables, and optional operationName.

Authentication

ALWAYS include the Authorization header for authenticated requests:

Authorization: Bearer 

This applies to Personal Access Tokens (PATs) and OAuth2 access tokens. The only query available without authentication is serverInfo.

Critical Warnings

NEVER omit the limit parameter on paginated fields -- Speckle has no default unlimited query. ALWAYS specify limit explicitly.

NEVER use offset-based pagination -- Speckle uses cursor-based pagination exclusively. ALWAYS use cursor + limit.

NEVER assume cursor: null means error -- a null cursor in the response means there are no more pages. ALWAYS check cursor to determine if more pages exist.

NEVER use items on ObjectCollection -- object children use the field name objects, not items. This is the only collection type with this inconsistency.

NEVER forget to declare GraphQL variables with their types in the operation signature -- missing $variable: Type! declarations cause parse errors.

NEVER use the legacy stream/branch/commit terminology in GraphQL queries -- ALWAYS use the current terminology: project (was stream), model (was branch), version (was commit).

NEVER use query or orderBy on object.children without understanding the performance cost -- these parameters trigger expensive SQL query paths on the server.

Queries

activeUser -- Authenticated User Profile

query ActiveUser {
  activeUser {
    id
    email
    name
    bio
    company
    avatar
    verified
    role
  }
}

Required scope: profile:read. Returns null if not authenticated.

activeUser with Projects (Paginated)

query UserProjects($limit: Int!, $cursor: String, $filter: UserProjectsFilter) {
  activeUser {
    projects(limit: $limit, cursor: $cursor, filter: $filter) {
      totalCount
      cursor
      items {
        id
        name
        description
        visibility
        role
        createdAt
        updatedAt
        workspaceId
      }
    }
  }
}

Filter fields: search, onlyWithRoles, workspaceId, personalOnly, includeImplicitAccess.

project(id) -- Get a Specific Project

query Project($projectId: String!) {
  project(id: $projectId) {
    id
    name
    description
    visibility
    allowPublicComments
    role
    createdAt
    updatedAt
    sourceApps
    workspaceId
  }
}

project with Models (Nested, Paginated)

query ProjectWithModels(
  $projectId: String!
  $modelsLimit: Int!
  $modelsCursor: String
  $modelsFilter: ProjectModelsFilter
) {
  project(id: $projectId) {
    id
    name
    models(limit: $modelsLimit, cursor: $modelsCursor, filter: $modelsFilter) {
      totalCount
      cursor
      items {
        id
        name
        displayName
        description
        createdAt
        updatedAt
        author { id name avatar }
      }
    }
  }
}

Filter fields: search, sourceApps, contributors, onlyWithVersions, ids, excludeIds.

model with Versions (Deeply Nested, Paginated)

query ModelWithVersions(
  $projectId: String!
  $modelId: String!
  $versionsLimit: Int!
  $versionsCursor: String
) {
  project(id: $projectId) {
    model(id: $modelId) {
      id
      name
      versions(limit: $versionsLimit, cursor: $versionsCursor) {
        totalCount
        cursor
        items {
          id
          referencedObject
          message
          sourceApplication
          createdAt
          previewUrl
          authorUser { id name avatar }
        }
      }
    }
  }
}

The referencedObject field contains the object ID for use with the REST API to download geometry/data.

serverInfo -- Server Metadata (No Auth Required)

query ServerInfo {
  serverInfo {
    name
    company
    description
    adminContact
    canonicalUrl
    version
    automateUrl
    scopes { name description }
    authStrategies { id name icon }
    workspaces { workspacesEnabled }
  }
}

Mutations

Project Mutations

# Create
mutation ProjectCreate($input: ProjectCreateInput) {
  projectMutations {
    create(input: $input) { id name description visibility }
  }
}

# Update
mutation ProjectUpdate($input: ProjectUpdateInput!) {
  projectMutations {
    update(update: $input) { id name description visibility }
  }
}

# Delete
mutation ProjectDelete($projectId: String!) {
  projectMutations {
    delete(id: $projectId)
  }
}

Visibility enum values: PRIVATE, UNLISTED, PUBLIC, WORKSPACE.

Model Mutations

# Create
mutation ModelCreate($input: CreateModelInput!) {
  modelMutations {
    create(input: $input) { id name displayName description }
  }
}

# Update
mutation ModelUpdate($input: UpdateModelInput!) {
  modelMutations {
    update(input: $input) { id name displayName description }
  }
}

# Delete
mutation ModelDelete($input: DeleteModelInput!) {
  modelMutations {
    delete(input: $input)
  }
}

CreateModelInput requires: name, projectId. Optional: description.

Version Mutations

# Create
mutation VersionCreate($input: CreateVersionInput!) {
  versionMutations {
    create(input: $input) { id referencedObject message createdAt }
  }
}

# Move to different model
mutation VersionMoveToModel($input: MoveVersionsInput!) {
  versionMutations {
    moveToModel(input: $input) { id }
  }
}

# Delete
mutation VersionDelete($input: DeleteVersionsInput!) {
  versionMutations {
    delete(input: $input)
  }
}

CreateVersionInput requires: objectId, modelId, projectId. Optional: message, sourceApplication, parents.

Webhook Mutations

mutation WebhookCreate($webhook: WebhookCreateInput!) {
  webhookCreate(webhook: $webhook)
}

mutation WebhookUpdate($webhook: WebhookUpdateInput!) {
  webhookUpdate(webhook: $webhook)
}

mutation WebhookDelete($webhook: WebhookDeleteInput!) {
  webhookDelete(webhook: $webhook)
}

WebhookCreateInput fields: streamId (project ID), url, description, triggers, secret, enabled. Requires streams:write scope and Stream Owner role.

API Token Mutations

mutation TokenCreate($token: ApiTokenCreateInput!) {
  apiTokenCreate(token: $token)
}

mutation TokenRevoke($token: String!) {
  apiTokenRevoke(token: $token)
}

Both require scope: tokens:write. apiTokenCreate returns the token string -- ALWAYS store it immediately as it cannot be retrieved again.

---

Subscriptions

Speckle uses WebSocket-based GraphQL subscriptions. ALWAYS authenticate with the same Bearer token.

subscription UserProjectsUpdated {
  userProjectsUpdated {
    id
    type
    project { id name visibility role }
  }
}

subscription ProjectModelsUpdated($id: String!, $modelIds: [String!]) {
  projectModelsUpdated(id: $id, modelIds: $modelIds) {
    id
    type
    model { id name displayName updatedAt }
  }
}

subscription ProjectVersionsUpdated($id: String!) {
  projectVersionsUpdated(id: $id) {
    id
    modelId
    type
    version { id referencedObject message createdAt }
  }
}

Subscription type values: CREATED, UPDATED, DELETED (models/versions) or ADDED, REMOVED (user projects).

---

Cursor-Based Pagination

Every paginated collection follows this structure:

type SomeCollection {
  totalCount: Int!
  cursor: String       # null when no more pages
  items: [SomeType!]!  # EXCEPTION: ObjectCollection uses "objects"
}

Pagination Loop Pattern

# Page 1: omit cursor
query { project(id: "abc") { models(limit: 25) { items { id name } cursor totalCount } } }

# Page N: pass returned cursor
query { project(id: "abc") { models(limit: 25, cursor: "returned-cursor") { items { id name } cursor totalCount } } }

ALWAYS stop iterating when cursor is null. Typical limits: 25 for models/versions, 100 for objects.

Collection Types

| Collection | Items Field | Parent Context | |------------|-------------|----------------| | UserProjectCollection | items | activeUser.projects | | ModelCollection | items | project.models | | VersionCollection | items | model.versions | | ObjectCollection | objects | object.children | | WebhookCollection | items | project.webhooks |

---

Error Response Format

GraphQL errors follow the standard format:

{
  "errors": [
    {
      "message": "You do not have the required server role",
      "extensions": {
        "code": "FORBIDDEN"
      }
    }
  ],
  "data": null
}

ALWAYS check for the errors array in responses. A response can contain BOTH data and errors (partial success).

Common error codes: FORBIDDEN, UNAUTHENTICATED, STREAM_NOT_FOUND, BAD_USER_INPUT.
