Link in Bio Script with Stripe Billing

A successful link-in-bio SaaS requires an automated monetization engine. Without integrated recurring subscriptions, manual invoicing creates administrative drag that prevents your software platform from scaling.

In this implementation guide, we configure a link in bio script with stripe billing using Bibiolink. You will learn how to connect production API credentials, configure webhooks, establish recurring subscription tiers, issue promotional coupons, and manage plan upgrades with zero middleman transaction cuts.

Many turnkey SaaS platforms force transactions through proprietary middleman gateways or take a 1% to 10% royalty on every subscription payment.

Bibiolink contains direct, native payment integrations. When an end user subscribes to your Pro or Business tier:

• Funds flow directly into your verified merchant Stripe account.
• You pay standard Stripe processing fees (e.g. 2.9% + 30¢) without platform markups.
• Customer payment methods (credit cards, Apple Pay, Google Pay) remain securely tokenized within Stripe's PCI-DSS Level 1 compliant infrastructure.

In addition to Stripe, Bibiolink supports PayPal, Lemon Squeezy, Razorpay, and manual bank transfer for complete global payment coverage.

To begin collecting recurring subscription revenue:

1. Register a verified account at stripe.com.
2. Complete your business verification details to enable live payment processing.
3. Locate your API credentials under Developers → API Keys in the Stripe Dashboard. You will need:
   • Publishable Key: pk_live_...
   • Secret Key: sk_live_...
   • Webhook Signing Secret: whsec_...

Connecting Stripe inside Bibiolink requires no code modifications:

1. Log into your Bibiolink administrative panel (https://yourdomain.com/admin).
2. Navigate to Settings → Payment Gateways → Stripe.
3. Toggle the Enable Stripe switch to active.
4. Input your Publishable Key and Secret Key.
5. Select your default platform currency (USD, EUR, GBP, CAD, AUD, etc.).
6. Click Save Gateway Settings.

Webhooks allow Stripe to notify your PHP backend when important recurring billing events take place (such as monthly renewals, failed credit card charges, or plan cancellations).

Step 1: Copy the Webhook Endpoint

In the Bibiolink admin dashboard, copy your unique webhook endpoint URL: https://yourdomain.com/api/webhooks/stripe

Step 2: Add Endpoint in Stripe Dashboard

1. Inside your Stripe Dashboard, go to Developers → Webhooks.
2. Click Add endpoint.
3. Paste your Bibiolink webhook URL.
4. Select the following essential events:
   • checkout.session.completed
   • invoice.paid
   • invoice.payment_failed
   • customer.subscription.updated
   • customer.subscription.deleted
5. Click Add endpoint and copy the resulting Signing secret (whsec_...) into your Bibiolink admin settings.

Bibiolink's webhook handler verifies event signatures using cryptographic hash checks, ensuring spoofed requests cannot grant unauthorized subscription access.

Under Admin → Subscription Plans, you can define custom packages:

Example High-Converting Tier Structure:

• Starter (Free): 5 active links, standard themes, no custom domains.
• Creator Pro ($9 / month or $89 / year): Unlimited links, all curated themes, Spotify & YouTube media embeds, link scheduling, click analytics, and NFC vCard generator.
• Agency / Business ($29 / month or $289 / year): Multi-tenant custom domain CNAME support, SSL/HTTPS routing, dynamic QR code studio, and priority email support.

You can also specify a free trial period (e.g., 7 or 14 days), automatically prompting users for payment details once the trial window expires.

---

Bibiolink includes an integrated promotional engine:

• Percentage Discounts: Create promotional codes (e.g. LAUNCH50 for 50% off the first year).
• Fixed Amount Discounts: Deduct a flat monetary amount from the checkout total.
• Duration Rules: Restrict coupons to single redemptions, a fixed number of billing cycles, or forever.
• Automated Downgrades: When a subscriber cancels their subscription in Stripe, their account remains active until the end of the paid billing period, after which it safely reverts to your Free plan.

Before going live, switch your Stripe toggle to Test Mode in the Bibiolink dashboard.

You can simulate recurring checkouts using Stripe's official test card numbers (4242 4242 4242 4242) to verify that user accounts automatically upgrade, confirmation emails dispatch, and database subscription records initialize seamlessly.

Once verified, paste your live keys to begin processing real subscriber payments.

Does Bibiolink take a percentage of my Stripe subscription revenue?

No. You own the software license outright (view pricing). Bibiolink collects zero royalties, zero transaction cuts, and zero per-seat fees. 100% of gateway payouts transfer directly into your business bank account.

Can I accept PayPal and Stripe at the same time?

Yes. Bibiolink allows multiple payment gateways to be active simultaneously. When users reach checkout, they can choose between credit cards via Stripe, one-click PayPal checkout, or localized options like Razorpay.

How are failed recurring payments handled?

When a recurring card payment fails, Stripe automatically dispatches an invoice.payment_failed webhook. Bibiolink marks the subscription as past due and sends an automated notification email prompting the subscriber to update their billing credentials.
