Using the Typeform API to Get Questions (with PHP examples)

Introduction to Typeform API Integration

Typeform is a versatile online form builder that allows businesses to create engaging and interactive forms, surveys, and quizzes. Its user-friendly interface and customizable design options make it a popular choice for collecting data and feedback from users.

Integrating with Typeform's API enables developers to automate data retrieval and management processes, enhancing the efficiency of data handling. For example, a developer might use the Typeform API to fetch questions from a form and dynamically display them on a website, allowing for seamless data integration and user interaction.

Setting Up Your Typeform Developer Account for API Integration

Before you can start using the Typeform API to retrieve questions, you'll need to set up a developer account and create an application within Typeform. This process involves registering your application to obtain the necessary credentials for OAuth 2.0 authentication.

Step-by-Step Guide to Creating a Typeform Developer Account

1. Sign Up or Log In:

   If you don't already have a Typeform account, visit the Typeform website and sign up for a free account. If you already have an account, simply log in.

2. Access Developer Apps:

   Once logged in, navigate to the upper-left corner and click the icon drop-down menu next to your organization name. Under the Organization section, select Developer Apps.

3. Register a New App:

   Click on Register a new app. Fill in the required fields, including the App Name, App Website, and Redirect URI(s). The Redirect URI is where users will be redirected after they log in and grant access to your app.

4. Save Your Credentials:

   After registering your app, you'll receive a client_id and client_secret. Make sure to copy and store these credentials securely as they will be used to authenticate your API requests.

Configuring OAuth 2.0 for Typeform API Access

Typeform uses OAuth 2.0 for secure API access. Follow these steps to configure OAuth 2.0 for your application:

1. Authorization Request:

   Direct users to the following URL to authorize your app:

   https://api.typeform.com/oauth/authorize?client_id={your_client_id}&redirect_uri={your_redirect_uri}&scope={scope1}+{scope2}

   Replace {your_client_id}, {your_redirect_uri}, and {scope} with your specific details.

2. Exchange Authorization Code for Access Token:

   Once the user authorizes your app, you'll receive a temporary authorization code. Use this code to request an access token:

   curl --request POST \
   --url https://api.typeform.com/oauth/token \
   --data-urlencode 'grant_type=authorization_code' \
   --data-urlencode 'code={temporary_authorization_code}' \
   --data-urlencode 'client_id={your_client_id}' \
   --data-urlencode 'client_secret={your_client_secret}' \
   --data-urlencode 'redirect_uri={your_redirect_uri}'

   Replace placeholders with your actual values.

For more detailed information, refer to the official Typeform documentation on applications and OAuth 2.0 scopes.

Making API Calls to Retrieve Questions from Typeform Using PHP

To interact with Typeform's API and retrieve questions from a form, you'll need to make authenticated API calls. This section will guide you through the process of setting up your PHP environment, making the API call, and handling the response.

Setting Up Your PHP Environment for Typeform API Integration

Before making API calls, ensure your PHP environment is properly configured. You'll need:

• PHP 7.4 or higher
• cURL extension enabled

Verify your PHP version and cURL installation by running the following command in your terminal:

php -v
php -m | grep curl

Making the API Call to Retrieve Questions from a Typeform Form

Once your environment is set up, you can proceed to make the API call. Use the following PHP code to retrieve questions from a specific Typeform form:

<?php
$accessToken = 'your_access_token';
$formId = 'your_form_id';
$url = "https://api.typeform.com/forms/$formId";

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Authorization: Bearer ' . $accessToken,
]);

$response = curl_exec($ch);
curl_close($ch);

$data = json_decode($response, true);

if (isset($data['fields'])) {
    foreach ($data['fields'] as $field) {
        echo 'Question: ' . $field['title'] . "<br>";
    }
} else {
    echo 'Failed to retrieve questions.';
}
?>

Replace your_access_token and your_form_id with your actual access token and form ID. This script initializes a cURL session, sets the necessary headers, and executes the request to the Typeform API.

Handling API Responses and Errors

After executing the API call, it's crucial to handle the response correctly. The above code checks if the 'fields' key exists in the response, indicating successful retrieval of questions. If not, it outputs an error message.

For more detailed error handling, consider checking the HTTP status code returned by the API. You can do this by adding the following lines:

$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($httpCode !== 200) {
    echo 'Error: ' . $httpCode;
}

This will display the HTTP status code if the request fails, helping you diagnose issues based on Typeform's error codes.

For more information on API calls and error handling, refer to the Typeform API documentation.

Conclusion and Best Practices for Typeform API Integration Using PHP

Integrating with the Typeform API using PHP can significantly enhance your application's data handling capabilities, allowing for seamless interaction with Typeform's versatile form-building platform. By following the steps outlined in this guide, you can efficiently retrieve questions from Typeform forms and integrate them into your applications.

Best Practices for Secure and Efficient Typeform API Integration

• Secure Storage of Credentials: Always store your client_id, client_secret, and access tokens securely. Avoid hardcoding them in your source code and consider using environment variables or secure vaults.
• Handling Rate Limits: Be mindful of Typeform's API rate limits to avoid service disruptions. Implement retry logic with exponential backoff to handle rate limit errors gracefully.
• Data Transformation and Standardization: When retrieving data from Typeform, consider transforming and standardizing it to fit your application's data model, ensuring consistency across different data sources.
