GeographQL Getting Started: Integration Guide (2026)

Getting started overview

Integrating GeographQL into a project generally involves a sequence of steps: creating an account, obtaining API credentials, and then constructing your first authenticated request to the GraphQL endpoint. GeographQL provides a GraphQL API for geocoding and reverse geocoding services, designed for applications requiring precise location data and flexible query structures GeographQL documentation. This guide focuses on the initial setup to facilitate a rapid integration.

The primary method of interaction is through a single GraphQL endpoint, which allows developers to specify the exact data fields needed, reducing over-fetching commonly associated with REST APIs GraphQL specification introduction. GeographQL supports client-side SDKs, notably for JavaScript, to streamline development, in addition to direct HTTP requests.

Here's a quick reference table outlining the key steps:

Create an account and get keys

To begin using GeographQL, you must first create an account. This process grants access to the developer dashboard where API keys are managed. GeographQL offers a free tier that includes 1,000 requests per month, which is suitable for initial development and testing GeographQL pricing details.

1. Navigate to the GeographQL Homepage: Open your web browser and go to the GeographQL official website.

2. Sign Up: Look for a 'Sign Up' or 'Get Started' button, typically located in the top right corner or prominent on the landing page. Follow the prompts to create a new account. This usually involves providing an email address and setting a password.

3. Verify Email (if required): Some registration processes include an email verification step. Check your inbox for a verification link from GeographQL and click it to activate your account.

4. Access the Dashboard: Once logged in, you will be directed to your developer dashboard. This is your central hub for managing your account, viewing usage statistics, and accessing API keys.

5. Retrieve API Key: Within the dashboard, there should be a section labeled 'API Keys' or 'Credentials'. Locate your default API key. It's crucial to treat this key as sensitive information, as it authenticates your requests and links them to your account's usage limits.

   Copy this API key. You will need to include it in the headers of all your GeographQL API requests for authentication.

It is recommended to store your API key securely and avoid hardcoding it directly into client-side applications. For server-side applications, environment variables are a common and secure practice for managing API keys.

Your first request

After obtaining your API key, you can make your first request to the GeographQL endpoint. GeographQL uses a single GraphQL endpoint for all operations. The following examples demonstrate how to make a basic geocoding request using cURL and JavaScript.

API Endpoint

The GeographQL API endpoint is typically in the format https://api.geographql.com/graphql GeographQL API reference. Always confirm the exact endpoint in your dashboard or the official documentation.

Authentication

Your API key must be included in the Authorization header of every request, prefixed with Bearer. For example: Authorization: Bearer YOUR_API_KEY.

Example 1: Geocoding with cURL

This example demonstrates how to geocode an address using a cURL command. Replace YOUR_API_KEY with your actual API key.

curl -X POST \
  https://api.geographql.com/graphql \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{"query": "query { geocode(address: \"1600 Amphitheatre Parkway, Mountain View, CA\") { latitude longitude formattedAddress }}"}'

The query requests the latitude, longitude, and formattedAddress for the given address. The response will be a JSON object containing these fields if the geocoding is successful.

Example 2: Geocoding with JavaScript (Fetch API)

For JavaScript applications, you can use the built-in Fetch API. This example assumes a browser or Node.js environment where fetch is available.

const API_KEY = 'YOUR_API_KEY'; // Replace with your actual API key
const GRAPHQL_ENDPOINT = 'https://api.geographql.com/graphql';

async function geocodeAddress(address) {
  try {
    const response = await fetch(GRAPHQL_ENDPOINT, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Authorization': `Bearer ${API_KEY}`
      },
      body: JSON.stringify({
        query: `
          query {
            geocode(address: "${address}") {
              latitude
              longitude
              formattedAddress
            }
          }
        `
      })
    });

    if (!response.ok) {
      throw new Error(`HTTP error! status: ${response.status}`);
    }

    const data = await response.json();
    console.log('Geocoding Result:', data.data.geocode);
    return data.data.geocode;
  } catch (error) {
    console.error('Error during geocoding:', error);
    return null;
  }
}

// Call the function with an address
geocodeAddress('1600 Amphitheatre Parkway, Mountain View, CA');

This JavaScript example performs the same geocoding query, handling the HTTP request and parsing the JSON response. The formattedAddress field in the response provides the standardized address recognized by the geocoding engine.

Common next steps

Once you've successfully made your first request, several common next steps can enhance your integration with GeographQL:

• Explore Reverse Geocoding: In addition to geocoding addresses to coordinates, GeographQL also supports reverse geocoding, converting coordinates back into human-readable addresses. This is useful for displaying locations on maps or for location-aware applications GeographQL API reference.

  
  query {
    reverseGeocode(latitude: 37.422, longitude: -122.084) {
      formattedAddress
      city
      country
    }
  }
      

• Integrate with a GraphQL Client: For more complex applications, consider using a dedicated GraphQL client library (e.g., Apollo Client, Relay) in your chosen programming language. These libraries simplify query construction, caching, and state management, providing a more robust development experience when working with GraphQL APIs Apollo Client documentation.

• Implement Error Handling: Develop robust error handling in your application. GeographQL responses will include an errors array in the JSON payload if issues occur (e.g., invalid API key, malformed query, rate limiting). Implement logic to parse these errors and provide appropriate feedback to users or logs.

• Monitor Usage: Regularly check your GeographQL dashboard to monitor your API usage. This helps you stay within your free tier limits or manage your paid plan effectively, preventing unexpected service interruptions due to exceeding quotas.

• Secure Your API Key: Ensure your API key is not exposed in client-side code or public repositories. For web applications, proxying requests through a backend server is a common security practice to hide API keys.

• Explore Advanced Features: Review the GeographQL documentation for advanced querying options, such as filtering results, specifying language preferences for addresses, or handling ambiguous addresses. Understanding these features can significantly improve the accuracy and relevance of your location data.

Troubleshooting the first call

Encountering issues during your first API call is common. Here are some troubleshooting steps for typical problems:

• Invalid API Key (HTTP 401 Unauthorized):

  • Check: Ensure your API key is correctly copied from your GeographQL dashboard.
  • Verify: Confirm the Authorization header is present and correctly formatted as Bearer YOUR_API_KEY, with a space between Bearer and your key.
  • Renew: If you suspect the key is compromised or revoked, generate a new one in your dashboard.

• Malformed GraphQL Query (HTTP 400 Bad Request / GraphQL Errors Array):

  • Syntax: Double-check the GraphQL query syntax for typos, missing commas, or incorrect field names. GraphQL is strict about its schema.
  • Escaping: For cURL or other string-based requests, ensure that double quotes within the JSON payload are correctly escaped (e.g., \"address\").
  • Schema: Refer to the GeographQL API reference to confirm the available fields and arguments for geocode and reverseGeocode mutations/queries.

• Network Issues (Connection Refused / Timeout):

  • Endpoint: Verify that the GraphQL endpoint URL is correct (https://api.geographql.com/graphql).
  • Firewall/Proxy: Check if your local network, firewall, or corporate proxy is blocking outbound requests to the GeographQL domain.
  • Internet Connection: Ensure your development machine has an active internet connection.

• Rate Limiting (HTTP 429 Too Many Requests):

  • Usage: If you're on the free tier, you might have exceeded the 1,000 requests/month limit. Check your dashboard for current usage.
  • Retry Logic: Implement exponential backoff for retrying failed requests to avoid hitting rate limits repeatedly for burst traffic.
  • Upgrade: If consistent high usage is expected, consider upgrading to a paid plan GeographQL pricing page.

• CORS Issues (Browser-specific):

  • Origin: If making requests directly from a browser-based application, ensure that your application's origin is allowed by GeographQL's CORS policy. Typically, modern APIs handle common origins, but if you encounter issues, check browser console errors.
  • Proxy: For stricter environments, consider proxying your requests through a backend server to bypass client-side CORS restrictions.

• Empty or Unexpected Response Data:

  • Query Fields: Confirm that the fields you are requesting in your GraphQL query (e.g., latitude, longitude) are correctly spelled and exist in the GeographQL schema.
  • Input Data: Ensure the address or coordinates provided in your query are valid and well-formed. Incorrect or ambiguous input may lead to null results.
