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.

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.

How I built it

Open Payment Host is a minimalist, yet performant 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.

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.

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 S3 API for secure file delivery.

What's next for Open Payment Host

Getting it to those who need it and adding more features through their feedback.
