Stripe Payment Links in Python: The 5-Minute Integration

Building a product? You need payments. Here's the fastest way to add Stripe to any Python app.

Why Payment Links?

Stripe offers two approaches:

1. Checkout Session - Build custom checkout pages
2. Payment Links - Pre-built hosted pages (what we're using)

Payment Links are:

• Zero frontend code needed
• Fully hosted by Stripe
• Mobile-optimized
• Support subscriptions, one-time, and donations

Step 1: Create Products in Stripe Dashboard

1. Go to Stripe Dashboard
2. Click "Add product"
3. Set name, description, price
4. Get the Payment Link URL

That's it. You now have a payment link like:
https://buy.stripe.com/xxx\

Step 2: Link It

\html
<a href="https://buy.stripe.com/xxx" class="buy-button">
Buy Now - $5
</a>
\\

Step 3: Handle Success (Optional)

Add ?success_url=...\ to redirect after payment:

\`python
from flask import Flask, request

app = Flask(name)

@app.route('/success')
def success():
session_id = request.args.get('session_id')
# Verify with Stripe API if needed
return "Thanks for your purchase!"
`\

Stripe appends {CHECKOUT_SESSION_ID}\ automatically if you include it in the success URL.

Webhook for Real Verification

For production, use webhooks:

\`python
import stripe
from flask import request

stripe.api_key = 'sk_live_xxx'

@app.route('/webhook', methods=['POST'])
def webhook():
payload = request.data
sig_header = request.headers.get('Stripe-Signature')

try:
    event = stripe.Webhook.construct_event(
        payload, sig_header, 'whsec_xxx'
    )
except ValueError:
    return 'Invalid payload', 400
except stripe.error.SignatureVerificationError:
    return 'Invalid signature', 400

if event['type'] == 'checkout.session.completed':
    session = event['data']['object']
    # Fulfill the order
    print(f"Payment received: {session['amount_total']}")

return 'ok'

`\

My Pricing Setup

For my products I use:

• $5 for 10 LinkedIn posts
• $7 for the directory guide
• $29-199 for submission services

Each is just a Payment Link pointing to the relevant success page.

Common Issues

1. Test vs Live mode - Use test keys during development
2. Webhook endpoint - Must be HTTPS in production
3. Success URL encoding - URL-encode special characters

Full Working Example

\`python
from flask import Flask, redirect

app = Flask(name)

STRIPE_PAYMENT_LINK = "https://buy.stripe.com/xxx"

@app.route('/buy')
def buy():
return redirect(STRIPE_PAYMENT_LINK)
`\

That's literally it. 5 lines to accept payments.
