Blogger + topropay

Lightweight HTML widget for Google's Blogger platform.

Get sandbox keys Read API docs →

Overview

Blogger only accepts HTML/JavaScript widgets, so topropay drops in as an HTML/JavaScript gadget that you place on any post or page. It is best suited to one-off purchases (donations, ebooks, sponsorship slots) rather than a full storefront.

What you get

Zero server requirement
Works on the free Blogger plan
Best for donations, one-off digital goods, sponsorship slots
Honest about platform limits — no full-store claim

Install in 3 steps

Add an HTML/JavaScript gadget

Blogger → Layout → Add a Gadget → HTML/JavaScript. Paste the topropay embed iframe.
Or embed inside a post

Switch the post editor to HTML view and paste the same iframe where the CTA should appear.
Receive the webhook elsewhere

Blogger can't run server code. Point the topropay webhook at any external worker (Cloudflare Workers, Vercel, a Google Apps Script web app).

Heads-up

Sandbox keys ship with simulated acquirers — every routing strategy (single, best, cascade) can be exercised end-to-end without contacting a real bank.

Ready to wire it up
