Stripe payments and subscriptions
Checkout, recurring billing and webhooks that keep subscription status in your database honest.
Backend and integrations
The bits behind the button, wired in properly.
Stripe payments and subscriptions, Resend email and third-party APIs are running in production on client apps I've built. I wire them into Base44 with the keys kept secret, the webhooks checked and the edge cases handled.

Running in production
Who it's for
Sound familiar?
Payments, subscriptions, email, webhooks and third-party APIs for Base44 apps. The parts behind the button, set up so they keep working when real users arrive.
- You need to take payments or run subscriptions.
- Your app's emails aren't arriving, or you can't send to people outside the app.
- You need to connect a third-party API and keep the keys out of the browser.
- Something should happen on a schedule, or when data changes, without anyone clicking a button.
What you get
What you actually get.
01 02 Email that arrives
Resend or Base44's built-in email, depending on who you're sending to and from which domain.
03 Third-party APIs, safely
Calls made from backend functions, keys stored as secrets, and a plan for when the other service doesn't cooperate.
04 Workflows and automations
Scheduled jobs and multi-step flows that run when your data changes, not when someone remembers.
05 Errors you can see
Failures get caught and logged instead of quietly vanishing, so you find out before your customers do.
How it goes
How it goes.
Five steps, in this order. You see progress at every one of them.
Step 01
Map the flow
What triggers what, which service owns which data, and what happens when a step fails.
Step 02
Test mode first
Payments and emails get built and tested without real money or real inboxes.
Step 03
Wire it in
Backend functions, secrets, webhooks and workflows, each one checked on its own.
Step 04
Break it on purpose
Failed cards, retried webhooks, missing fields. I try the bad paths so your users do not have to.
Step 05
Go live and hand over
Switch to live keys, watch the first real runs, then walk you through it.

FAQ
Questions people ask.
Something else on your mind? Ask me. I answer everything myself.
Ask a questionUsually, yes. The main job is making sure your database always knows who's paid, which means handling Stripe's webhooks properly rather than trusting the page someone lands on after checkout.
Base44's built-in SendEmail can always email people who have signed up to your app. Emailing outside addresses needs a paid plan and a verified custom domain. If you need your own sending domain and more control, Resend is the usual answer.
In secrets, read from backend functions. Never in the frontend code, where anyone can open the browser tools and copy them. Base44's security scan flags keys it finds in the wrong place.
If you're calling APIs with secret keys, handling webhooks or running logic you don't want in the browser, yes. Whether they're switched on depends on your Base44 plan, so check that first.
