Pinterest Getting Started: API Integration Guide (2026)

Getting started overview

Integrating with the Pinterest API involves a sequence of steps designed to ensure secure access and proper application registration. This guide outlines the process from account creation to making an initial API call. The Pinterest API enables developers to manage various aspects of the Pinterest platform, including creating and managing Pins, boards, and interacting with user data, all while adhering to Pinterest's platform policies and OAuth 2.0 authentication requirements.

The core process includes:

1. Creating a Pinterest account.
2. Accessing the developer portal and creating a new application.
3. Obtaining client credentials (Client ID and Client Secret).
4. Implementing OAuth 2.0 for user authorization.
5. Making an authenticated request to a Pinterest API endpoint.

The following table provides a quick reference for these initial integration steps:

Create an account and get keys

Before interacting with the Pinterest API, you need a Pinterest account. If you do not have one, register for a free account on the Pinterest website. This account will be used to access the developer portal and manage your applications.

Registering a new application

Once you have a Pinterest account, navigate to the Pinterest Developer site. Here, you will find options to create a new application. The process typically involves:

1. Logging in: Use your Pinterest account credentials to log into the developer portal.
2. Creating a new app: Select the option to create a new application. You will be prompted to provide details such as the application name, description, and a callback URL. The callback URL is critical for the OAuth 2.0 authorization flow, as it is where Pinterest redirects the user after they grant or deny permission to your application.
3. Reviewing terms: Agree to the Pinterest API Terms of Service.
4. Receiving credentials: Upon successful registration, Pinterest will provide you with a Client ID and a Client Secret. These are unique identifiers for your application and must be kept confidential. The Client ID is publicly visible, but the Client Secret should be treated like a password.

The Client ID and Client Secret are essential for initiating the OAuth 2.0 authorization process, which is how your application obtains user consent and an access token to make API calls on behalf of a user. For detailed instructions on application registration, refer to the Pinterest API authentication guide.

Your first request

Making your first request to the Pinterest API involves obtaining an access token through the OAuth 2.0 authorization flow and then using that token in your API calls. The Pinterest API primarily uses the Authorization Code Grant flow for web applications, which involves several steps:

1. Redirecting the user for authorization: Your application redirects the user's browser to a Pinterest authorization URL, including your Client ID, requested scopes (permissions), and the redirect URI.
2. User grants permission: The user logs into Pinterest (if not already logged in) and grants your application the requested permissions.
3. Pinterest redirects back: Pinterest redirects the user's browser back to your specified redirect URI, appending an authorization code to the URL.
4. Exchanging authorization code for an access token: Your application then makes a server-side request to Pinterest's token endpoint, exchanging the authorization code, your Client ID, and Client Secret for an access token.

Example: Fetching user profile information (Python)

This example demonstrates how to make an authenticated call to retrieve the authenticated user's profile information using Python, assuming you have already completed the OAuth 2.0 flow and obtained an access_token.

import requests

# Replace with your actual access token
ACCESS_TOKEN = "YOUR_ACCESS_TOKEN"

# Pinterest API endpoint for user profile
API_URL = "https://api.pinterest.com/v5/user_account"

headers = {
    "Authorization": f"Bearer {ACCESS_TOKEN}"
}

params = {
    "fields": "username,profile_image,website_url"
}

try:
    response = requests.get(API_URL, headers=headers, params=params)
    response.raise_for_status()  # Raise an exception for HTTP errors (4xx or 5xx)

    user_data = response.json()
    print("User Profile Data:")
    print(user_data)

except requests.exceptions.HTTPError as http_err:
    print(f"HTTP error occurred: {http_err}")
    print(f"Response content: {response.text}")
except requests.exceptions.ConnectionError as conn_err:
    print(f"Connection error occurred: {conn_err}")
except requests.exceptions.Timeout as timeout_err:
    print(f"Timeout error occurred: {timeout_err}")
except requests.exceptions.RequestException as req_err:
    print(f"An unexpected error occurred: {req_err}")

Example: Creating a Pin (cURL)

This cURL example demonstrates how to create a new Pin. This also assumes you have obtained an access_token with the necessary write_pins scope.

curl -X POST \
  'https://api.pinterest.com/v5/pins' \
  -H 'Authorization: Bearer YOUR_ACCESS_TOKEN' \
  -H 'Content-Type: application/json' \
  -d '{
    "board_id": "YOUR_BOARD_ID",
    "media_source": {
      "source_type": "image_url",
      "url": "https://example.com/image.jpg"
    },
    "link": "https://example.com/item",
    "title": "My New Pin Title",
    "description": "A description for my new Pin."
  }'

Remember to replace YOUR_ACCESS_TOKEN, YOUR_BOARD_ID, and the media source URL with your actual values. The board_id can be obtained from the List Boards endpoint.

Common next steps

After successfully making your first API call, you can explore more advanced features and integrations:

• Explore other endpoints: Review the Pinterest API Reference to understand the full range of available endpoints for managing Pins, boards, sections, users, and advertising campaigns.
• Implement webhooks: For real-time updates and event-driven architectures, consider implementing webhooks. Webhooks allow Pinterest to notify your application of specific events, such as new Pins or user interactions, without constant polling. For general information on webhooks, refer to the Twilio Webhooks documentation.
• Utilize SDKs: Pinterest provides official SDKs for Python, PHP, Java, Node.js, Ruby, and Swift. Using an SDK can simplify API interactions by handling authentication, request signing, and response parsing. Refer to the Pinterest SDK documentation for setup and usage details.
• Error handling and logging: Implement robust error handling and logging within your application to gracefully manage API rate limits, authentication failures, and other potential issues.
• Optimize for performance: Consider caching strategies for frequently accessed data and using pagination where available to manage large datasets efficiently.
• Understand rate limits: Familiarize yourself with Pinterest's API rate limits to avoid interruptions in service.
• Review platform policies: Regularly review Pinterest's Platform Policy to ensure your application remains compliant.

Troubleshooting the first call

Encountering issues during your first API call is common. Here are some troubleshooting tips:

• Check your access_token: Ensure your access token is valid and has not expired. Access tokens typically have a limited lifespan. If expired, you'll need to refresh it using the refresh token obtained during the OAuth flow.
• Verify scopes: Confirm that your access token has the necessary permissions (scopes) for the endpoint you are trying to access. For example, creating a Pin requires write_pins.
• Incorrect endpoint or HTTP method: Double-check that you are using the correct API endpoint URL and the appropriate HTTP method (GET, POST, PUT, DELETE) as specified in the Pinterest API Reference.
• Malformed JSON payload: If you are sending a POST or PUT request, ensure your JSON payload is correctly formatted and includes all required fields. Use a JSON validator if necessary.
• Authorization header format: The Authorization header should be in the format Bearer YOUR_ACCESS_TOKEN. Ensure there are no typos or extra spaces.
• Rate limiting: If you receive 429 Too Many Requests errors, you have hit a rate limit. Implement exponential backoff or wait before retrying your request.
• Network issues: Verify your internet connection and check for any firewall or proxy issues that might be blocking your requests to api.pinterest.com.
• Review Pinterest developer logs: The Pinterest developer portal may offer logs or insights into API call failures related to your application.
• Consult documentation: Always refer to the Pinterest API error codes documentation for specific error messages and their meanings.
