Webhook to trigger lock for fridge
Budget: $30 – $250 USD
QR-pay-to-unlock fridge** using the *no-code / low-dev* method

Project: QR-Payment Activated Refrigerator Lock
Retrofit a small refrigerator so that students can **scan a QR code, pay via Stripe or Square, and automatically unlock the fridge for ~6–10 seconds** to grab a cold water. The system doesn’t need high security — just a fun, autonomous deterrent to prevent theft.
---
What We Need
We’re looking for someone who can:
1. Configure a **payment link (Stripe or Square)** that triggers a **Zapier or IFTTT webhook** after a successful payment.
2. Set up a **Raspberry Pi Zero W** (or similar microcontroller) to receive that webhook and trigger a **relay** to power a **12 V solenoid or maglock** for a few seconds.
3. Provide **working Python code** (Flask or similar) for the webhook receiver and relay control.
4. Help wire the lock + relay + Pi, and show how to make it boot automatically.
5. Provide a simple **test/demo setup** (LED indicator optional) so I can easily replicate it on site.

* Stripe or Square Payment Link → Zapier Webhook
* Raspberry Pi Zero W (Wi-Fi enabled)
* 5 V Relay Module
* 12 V Solenoid or Magnetic Lock
* 12 V DC Power Supply
* (Optional) LED indicator for “Unlocked” status
---
Deliverables
* Step-by-step setup instructions (from payment link to hardware wiring).
* Python script(s) with brief comments.
* Schematic or wiring diagram.
* Optional: printable “Scan to Pay & Unlock” QR signage template.
* Short remote walkthrough / video call to verify it’s running.
---
---
Ideal Freelancer
* Experienced with **Raspberry Pi**, **relays**, and **webhooks**.
* Comfortable using **Zapier/IFTTT** or lightweight API automations.
* Communicative and able to document clearly for a non-engineer end-user.
* (Bonus) Experience with Stripe/Square webhooks or IoT projects.
---
This isn’t mission-critical security — it’s more of a clever, self-serve fridge experiment.
* Examples of small IoT or Raspberry Pi projects you’ve done.
* Which platform you’d prefer (Stripe vs. Square + Zapier vs. IFTTT).
* Estimated time to deliver and total project cost.
