How I Built a Zero-Cost Python Webhook Engine to Bypass a High-Friction Voting System

When I entered the CANEX Create-Thon competition, I quickly realized I wasn't just competing against other creators but rather I was also competing against bad UX. The Gebeya platform requires users to complete a full email sign-in just to cast their vote. For organic traffic, that level of friction means a 90% drop-off rate. Instead of begging for votes, I decided to engineer a bypassing channel. I've detailed below how I built the zero-cost automated funnel using a code-first architecture: The Intermediary Frontend (Astro & Tailwind) I didn't send people straight to the voting portal. I built a lightning-fast mobile landing page in Astro. The goal was to establish a "Value Exchange" before they hit the login screen. I promised a reward: if they vote and upload a screenshot, my server generates a custom Spotify playlist for them.The Webhook Engine (Python FastAPI) Instead of paying for premium automation tools, I spun up a lightweight Python FastAPI server hosted on a free tier. It listens for a specific trigger keyword on social media.The Auto-DM & Reward Trigger When the server catches the webhook, it instantly DMs the user the Astro landing page. Once they upload the screenshot of their vote, a secondary Python script queries the Spotify API, generates the custom queue, and emails it back. I am testing the load capacity of this funnel over the next 8 days. If you want to see how fast the server responds and test the webhook architecture yourself, you can run through the live flow and drop a vote here: https://dala.gebeya.com/cannex-vote/623f28fd-df93-49c8-8198-55825741a4ba Would love to hear how you would optimize the Python routing in the comments.
