GraphQL API Quickstart

This guide will help you make your first GraphQL query to the SensorUp API and understand the basics of working with the federated graph.

​
Prerequisites

Before you begin, you’ll need:
  • Access to a SensorUp environment (demo, staging, or production)
  • Valid authentication credentials (see Authentication)
  • A GraphQL client or HTTP tool (curl, Postman, or a programming language client)

​
Your First Query

​
Using curl

curl -X POST https://customer-demo.sensorup.com/api/graphql \
  -H "Content-Type: application/json" \
  -H "x-sensorup-sessionid: YOUR_SESSION_ID" \
  -d '{
    "query": "query { session { username authenticated } }"
  }'

​
Response

{
  "data": {
    "session": {
      "username": "your-username",
      "authenticated": true
    }
  }
}

​
Understanding the Query Structure

GraphQL queries have three main components: 
query {           # Operation type (query, mutation, or subscription)
  session {       # Root field - what you're querying
    username      # Selection - fields you want returned
    authenticated
  }
}

​
Common Query Patterns

​
Querying Asset Profiles

query GetAssetProfiles {
  assetProfiles {
    all(first: 10) {
      edges {
        node {
          profile
          title
          displayNameProperty
        }
      }
      pageInfo {
        hasNextPage
        endCursor
      }
    }
  }
}

​
Getting Specific Asset by ID

query GetAsset($profileId: ID!, $assetId: ID!) {
  assetProfiles {
    byId(profile: $profileId) {
      profile
      title
      assetById(id: $assetId) {
        id
        displayName
        properties
        geometry
      }
    }
  }
}
Variables: 
{
  "profileId": "your-profile-id",
  "assetId": "your-asset-id"
}

​
Querying Issues

query GetIssues {
  issues {
    all(first: 10) {
      edges {
        node {
          id
          displayName
          status
          createdAt
          audit {
            createdBy {
              userId
            }
          }
        }
      }
    }
  }
}

​
Making Mutations

Mutations modify data on the server. All mutations follow a consistent pattern with result types that include correlationId and errors.

​
Creating an Asset Filter

mutation CreateAssetFilter($input: CreateAssetFilterInput!) {
  createAssetFilter(input: $input) {
    assetFilter {
      id
      displayName
      profile
    }
    correlationId
    errors {
      message
      type
    }
  }
}
Variables: 
{
  "input": {
    "id": "my-filter-id",
    "displayName": "My Asset Filter",
    "profile": "asset-profile-id",
    "subProfiles": []
  }
}

​
Pagination

The API uses Relay-style cursor-based pagination: 
query PaginatedAssets($first: Int!, $after: String) {
  assetProfiles {
    byId(profile: "your-profile") {
      assets(first: $first, after: $after) {
        edges {
          node {
            id
            displayName
          }
        }
        pageInfo {
          hasNextPage
          hasPreviousPage
          startCursor
          endCursor
        }
      }
    }
  }
}
First page: 
{ "first": 10 }
Next page: 
{ "first": 10, "after": "cursor-from-previous-page" }

​
Error Handling

​
Query Errors

GraphQL returns errors in the errors array: 
{
  "errors": [
    {
      "message": "Cannot query field 'invalidField' on type 'Asset'",
      "locations": [{ "line": 3, "column": 5 }]
    }
  ]
}

​
Mutation Errors

Mutations return errors in the result type: 
{
  "data": {
    "createAssetFilter": {
      "assetFilter": null,
      "correlationId": "abc-123",
      "errors": [
        {
          "message": "Asset filter with this ID already exists",
          "type": "DUPLICATE_ID"
        }
      ]
    }
  }
}

​
Using GraphQL Clients

​
JavaScript/TypeScript

// Using graphql-request
import { request, gql } from 'graphql-request'

const query = gql`
  query {
    session {
      username
      authenticated
    }
  }
`

const data = await request(
  'https://customer-demo.sensorup.com/api/graphql',
  query,
  {},
  { 'x-sensorup-sessionid': sessionId }
)

​
Python

# Using gql
from gql import gql, Client
from gql.transport.requests import RequestsHTTPTransport

transport = RequestsHTTPTransport(
    url='https://customer-demo.sensorup.com/api/graphql',
    headers={'x-sensorup-sessionid': session_id}
)

client = Client(transport=transport, fetch_schema_from_transport=True)

query = gql("""
    query {
        session {
            username
            authenticated
        }
    }
""")

result = client.execute(query)
