Inspiration
As an indie we need payment hosts to host our content and process the sales for our books, games, art, newsletters etc. But their commissions can take out a huge chunk out of our income. Often our product descriptions can fall short and we need the help of marketing personnel to write it.
What it does
Open Payment Host addresses this problem by providing an easily deployable payment host which we can integrate with a leading payment processor like Square which offers pay as you go plan. Open Payment Host comes with Google AI's PaLM API powered editor which helps us write amazing product descriptions.

How I built it
Open Payment Host is a minimalist, yet performant and secure Go web application. I designed it from the ground up to be an isolated containerized application.
Payment processor for Open Payment Host was implemented using Square's payments API, subscriptions API, Web SDK and Webhook.
AI autocomplete for product description was implemented using Google AI's PaLM API
Open Payment Host is dockerized and can be easily self-hosted using helper scripts for development and production environment.
The design choices include but not limited to using Sqlite3 for database, Instead of an external database server. Using Go templates with Tailwind CSS for UI instead of JavaScript front-end frameworks.
Challenges I ran into
Ensuring secure handling of customer's credit card and ensuring compliance was a challenge, I addressed it by using Square's Web SDK.
Lack of Go SDK for PaLM API was a challenge, I overcame it by using their REST API.
Accomplishments that I'm proud of
I was able to build a secure, production ready payments host within the stipulated period of the hackathon.
What I learned
Integrating payment processor in a payment host using Square's Payments API, Subscriptions API, Web SDK and Webhook. Integrating PaLM AI API for sentence autocomplete.
What's next for Open Payment Host
Getting it to those who need it and adding more features through their feedback.
