What is Stripe Connect Express API?

Stripe Connect is a powerful platform that allows you to facilitate payments between multiple parties. Think of it as the backbone for marketplaces, platforms, and any business model where you need to handle payments for multiple vendors or service providers. Stripe Connect Express API is a specific integration option within Stripe Connect, designed for platforms that want a streamlined, pre-built onboarding experience for their connected accounts.

Key Concepts of Stripe Connect Express API

Before diving into the code, let's cover some essential concepts:

  • Platform: Your application or website that connects sellers or service providers.
  • Connected Account: The Stripe account representing a seller or service provider on your platform.
  • Account Link: A Stripe object that represents the onboarding flow for a connected account.
  • Transfer: Moving funds from your platform account to a connected account.
  • Charges: Payments collected from customers.

Understanding these concepts is crucial for effectively using the Stripe Connect Express API. Your platform is the central hub that facilitates transactions between customers and connected accounts. Each connected account represents a unique individual or business that uses your platform to offer goods or services. The account link is the key to onboarding these connected accounts, guiding them through the process of providing necessary information and verifying their identity. Transfers are used to distribute funds from your platform account to the connected accounts, ensuring that they receive their earnings for the transactions they've facilitated. Charges, on the other hand, represent the payments collected from customers for the goods or services they've purchased through your platform. By grasping these fundamental concepts, you'll be well-equipped to navigate the complexities of the Stripe Connect Express API and build a robust and scalable payment solution for your platform. Moreover, understanding how these concepts relate to each other will enable you to troubleshoot issues more effectively and optimize your integration for maximum performance and efficiency. So, take the time to familiarize yourself with these terms, and you'll be well on your way to mastering the Stripe Connect Express API.

Setting Up Stripe Connect

First, you'll need a Stripe account. If you don't have one, sign up at stripe.com.

  1. Enable Connect: In your Stripe dashboard, navigate to Connect and enable the platform.
  2. Configure Settings: Set up your platform's business information, payout schedule, and other relevant settings.
  3. Get Your API Keys: Retrieve your publishable and secret keys. Keep these safe!

Configuring your Stripe Connect settings is a critical step in ensuring that your platform operates smoothly and complies with all relevant regulations. Your platform's business information, including your legal name, address, and tax identification number, must be accurately entered to avoid any issues with verification or payouts. The payout schedule determines how frequently your connected accounts will receive their earnings, so it's important to choose a schedule that aligns with their needs and your business model. You can also configure other settings such as the default currency, the types of accounts you'll be connecting, and the level of access you want to grant to your connected accounts. Remember, protecting your API keys is of paramount importance. These keys are like the keys to your kingdom, and if they fall into the wrong hands, they can be used to access and manipulate your Stripe account. Treat them with the utmost care and never share them with anyone or store them in a public repository. By taking the time to properly configure your Stripe Connect settings and safeguard your API keys, you'll be setting yourself up for success and ensuring that your platform operates in a secure and compliant manner.

Implementing Stripe Connect Express API: A Step-by-Step Guide

Let's walk through the process of integrating Stripe Connect Express API into your platform.

Step 1: Create a Connected Account

Use the Stripe API to create a connected account for your seller or service provider.

import stripe
stripe.api_key = 'YOUR_SECRET_KEY'

account = stripe.Account.create(
    type='express',
    country='US',
    email='seller@example.com',
)

account_id = account['id']
print(f"Account ID: {account_id}")

Replace 'YOUR_SECRET_KEY' with your actual Stripe secret key and adjust the country and email parameters accordingly. The type parameter should be set to 'express' for Express accounts. Remember to handle errors appropriately and store the account_id securely in your database. Creating a connected account is the foundation for enabling sellers or service providers to receive payments through your platform. The stripe.Account.create() method allows you to programmatically create a new account in Stripe's system, specifying the type of account, the country in which it's based, and the email address associated with it. The country parameter is crucial as it determines the legal and regulatory requirements that apply to the account. The email parameter is used for communication purposes, such as sending onboarding instructions and payment notifications. Once the account is created, Stripe returns a unique account_id that you'll need to store securely in your database. This account_id is used to identify the connected account in subsequent API calls, such as creating account links and processing transfers. By creating a connected account, you're essentially setting up a virtual bank account for your seller or service provider within the Stripe ecosystem, allowing them to seamlessly receive payments from customers through your platform.

Step 2: Create an Account Link

Generate an Account Link for the connected account. This link will redirect the user to Stripe to complete their onboarding.

account_link = stripe.AccountLink.create(
    account=account_id,
    refresh_url='https://your-platform.com/reauth',
    return_url='https://your-platform.com/return',
    type='account_onboarding',
)

account_link_url = account_link['url']
print(f"Account Link URL: {account_link_url}")

Replace 'https://your-platform.com/reauth' and 'https://your-platform.com/return' with your platform's URLs. The refresh_url is where the user will be redirected if the link expires or becomes invalid. The return_url is where the user will be redirected after completing the onboarding process. The type parameter should be set to 'account_onboarding'. Generating an account link is the mechanism by which you guide your connected accounts through the Stripe onboarding process. The stripe.AccountLink.create() method generates a unique URL that you can redirect your users to. This URL takes them to a Stripe-hosted page where they can provide the necessary information to verify their identity and connect their bank account. The refresh_url is a crucial parameter as it provides a way for users to re-authenticate if their session expires or if they need to update their information. The return_url is where users are redirected after they've completed the onboarding process, allowing you to seamlessly integrate the onboarding flow into your platform's user experience. The type parameter specifies the type of account link you're creating, which in this case is 'account_onboarding' for onboarding new connected accounts. By generating an account link, you're effectively offloading the complexities of onboarding to Stripe, ensuring that your users have a secure and compliant experience while minimizing the amount of code you need to write and maintain.

Step 3: Redirect the User

Redirect the user to the account_link_url obtained in the previous step.

# In your web framework (e.g., Flask, Django):
from flask import redirect

@app.route('/onboard')
def onboard():
    # Create account link (as shown in Step 2)
    account_link = stripe.AccountLink.create(
        account=account_id,
        refresh_url='https://your-platform.com/reauth',
        return_url='https://your-platform.com/return',
        type='account_onboarding',
    )
    return redirect(account_link['url'])

This example uses Flask, but the concept is the same for other web frameworks. Simply redirect the user to the generated URL. Redirecting the user to the account_link_url is the crucial step that initiates the Stripe onboarding process. When a user clicks on the link, they're redirected to a Stripe-hosted page where they're guided through the process of providing the necessary information to verify their identity and connect their bank account. This page is designed to be user-friendly and secure, ensuring that users feel comfortable providing their sensitive information. The redirection process is seamless and transparent, allowing users to easily navigate between your platform and the Stripe onboarding page. Once the user has completed the onboarding process, they're automatically redirected back to your platform via the return_url that you specified when creating the account link. This allows you to seamlessly integrate the onboarding flow into your platform's user experience, providing a smooth and consistent experience for your users. By redirecting the user to the account_link_url, you're effectively delegating the complexities of onboarding to Stripe, ensuring that your users have a secure and compliant experience while minimizing the amount of code you need to write and maintain.

Step 4: Handle the Return

When the user returns to your platform, check the status of the connected account.

account = stripe.Account.retrieve(account_id)
if account['details_submitted']:
    print("Account onboarding complete!")
else:
    print("Account onboarding incomplete.")

The details_submitted field indicates whether the user has completed the onboarding process. You can also check other fields, such as charges_enabled and payouts_enabled, to determine if the account is fully functional. Handling the return from Stripe is essential for determining whether the user has successfully completed the onboarding process. When the user is redirected back to your platform via the return_url, you need to verify the status of their connected account to ensure that they've provided all the necessary information and that their account is fully functional. The stripe.Account.retrieve() method allows you to retrieve the account details from Stripe's system, and the details_submitted field indicates whether the user has completed the onboarding process. You can also check other fields, such as charges_enabled and payouts_enabled, to determine if the account is fully capable of processing charges and receiving payouts. If the account is not fully functional, you can redirect the user back to the account link to complete the onboarding process or provide them with instructions on how to resolve any issues. By handling the return from Stripe and verifying the status of the connected account, you can ensure that your platform is only working with fully verified and functional accounts, minimizing the risk of fraud and ensuring that your users have a smooth and seamless payment experience.

Step 5: Create Charges and Transfers

Now you can create charges and transfer funds to the connected account.

charge = stripe.Charge.create(
    amount=1000,
    currency='usd',
    source='tok_visa',
    transfer_data={
        'destination': account_id,
    },
)

print(f"Charge ID: {charge['id']}")

This example creates a charge of $10.00 and transfers the funds to the connected account. Replace 'tok_visa' with a valid payment token or source. Creating charges and transfers is the ultimate goal of integrating with the Stripe Connect Express API. Once a connected account is onboarded and verified, you can start processing payments on their behalf and transferring funds to their account. The stripe.Charge.create() method allows you to create a charge, specifying the amount, currency, and payment source. The transfer_data parameter is used to specify the destination account for the funds, which in this case is the account_id of the connected account. By creating charges and transfers, you're enabling your sellers or service providers to receive payments from customers through your platform and ensuring that they get paid for their goods or services. This is the core functionality of Stripe Connect Express API, and it's what makes it such a powerful tool for building marketplaces and platforms that facilitate payments between multiple parties. Remember to handle errors appropriately and provide clear feedback to your users throughout the payment process.
