Requirements
What Stripe Integration for FastAPI needs
What it does
Stripe on your FastAPI app — the route is not a card form
Bacodo integrates Stripe into the FastAPI project you already have. After handover, routers, dependencies, and settings live in your repo. You still own the Stripe account, API keys, and Stripe fees. FastAPI never stores PAN.
Problem it solves
A production FastAPI Stripe path needs the official stripe package, PaymentIntent creation in a dependency or service, and construct_event on the raw request bytes. If you await request.json() first, the signature check fails. That is the usual FastAPI webhook bug.
How it lands in the project
We add an APIRouter, pydantic-settings (or your existing Settings), a create-intent endpoint with a Pydantic request model, and a webhook that uses await request.body(). Order writes go through SQLAlchemy, the repository you already have, or whatever store the FastAPI app already uses — not Django ORM.
Why it saves development time
Your team skips the first production FastAPI Stripe implementation: raw-body webhooks, idempotent event handling, SCA-aware PaymentIntents, and a handover that documents test-to-live keys.
Who it is for
Python backend engineers and agencies that already run FastAPI. If your API is Django, that is Stripe Integration for Django — we do not paste urls.py into a FastAPI app.
Key features
What Stripe Integration for FastAPI includes
Official stripe SDK behind a FastAPI router
Create PaymentIntents with the stripe Python library from a FastAPI dependency or service. The secret key comes from Settings / env — never from a Pydantic model the client posts.
Webhook uses request.body(), not request.json()
stripe.Webhook.construct_event needs the exact bytes Stripe signed. The FastAPI route reads await request.body() and the Stripe-Signature header. Parsing JSON first is how FastAPI Stripe integrations fail in production.
FastAPI order state after payment_intent.succeeded
Fulfillment runs in the FastAPI handler after construct_event succeeds, not after a thank-you page. We update your existing order or entitlement record.
FastAPI test mode then live Stripe keys
Ship FastAPI with Stripe test keys and the webhook secret first. Going live is a documented env and Dashboard endpoint cutover, not an add-on license.
Idempotent FastAPI webhook handling
Stripe retries. The FastAPI handler keys off event.id (or PaymentIntent id) so a duplicate POST does not double-fulfill.
Your FastAPI clients stay clients
A React, Next.js, or mobile app only receives a publishable key and a short-lived client_secret from this FastAPI app. This add-on is the FastAPI server path, not Elements inside a Jinja template.
Use cases
When Stripe Integration for FastAPI fits
Existing FastAPI commerce or booking API
You already create orders in FastAPI and need the API to create PaymentIntents and mark those orders paid from webhooks.
Agency handing a FastAPI client API to production
You need a maintainable Stripe router in FastAPI, source in the client repo, and a documented live-key cutover instead of a one-off script next to main.py.
SaaS billed through a FastAPI app
FastAPI creates the first PaymentIntent or attaches a payment method. Recurring Stripe Billing stays on the server. Heavy Billing work may need a Custom Quote.
FastAPI behind a separate frontend
Next.js, React, or mobile already calls this FastAPI app. Stripe Integration for FastAPI is the API side only — frontend Stripe.js is a different platform landing if you need that too.
Demo
FastAPI Stripe webhook path preview
Preview the FastAPI server path: create PaymentIntent, receive POST /webhooks/stripe, construct_event on request.body(), update order state. A live sandbox against your Stripe account is available after compatibility check. This page does not process real charges and does not collect cards in FastAPI.
How it works
How Stripe Integration for FastAPI is delivered
Standard Bacodo add-on workflow, with FastAPI-specific checks for uvicorn, pydantic-settings, async vs sync stripe calls, and the store your routes already use.
01
Select FastAPI Stripe
Confirm Stripe Integration for FastAPI and whether day one is PaymentIntents, Checkout Sessions, or both on the FastAPI app.
02
FastAPI compatibility check
Review FastAPI / Python versions, pydantic v2, existing order persistence (SQLAlchemy or otherwise), auth dependencies, and whether you already have a Stripe account.
03
Integrate into FastAPI
Add the stripe package, an APIRouter, create-intent endpoint, and a webhook that verifies signatures on await request.body().
04
Configure the FastAPI app
Wire Settings from env: secret key, publishable key for clients, webhook secret, and the public HTTPS URL Stripe will call.
05
Test the FastAPI payment path
Run Stripe CLI or Dashboard test events against the FastAPI webhook, plus create-intent and decline paths. Confirm request.json() would fail signature as expected.
06
Handover the FastAPI source
Deliver FastAPI source, env notes, and a live-key checklist. The FastAPI implementation is yours to maintain.
Architecture
How Stripe connects to a FastAPI project
The FastAPI process holds the secret key. Clients ask a FastAPI route to create a PaymentIntent. Stripe notifies FastAPI by webhook. FastAPI verifies the signature on request.body(), then writes order state.

Supported technologies
What Stripe Integration for FastAPI actually uses
FastAPI on Python
Current FastAPI on a Python version the stripe SDK accepts, typically served with uvicorn. This is not Django and not Flask — we do not add urls.py or Flask blueprints.
Official stripe Python library
PaymentIntents, Checkout Sessions, and Webhook.construct_event. Sync calls from async routes are scoped honestly (threadpool or StripeClient async) — we do not pretend blocking stripe is free inside async def.
Your FastAPI persistence
Order or entitlement updates stay on SQLAlchemy, another store, or the repository you already have. This add-on does not invent a Django model.
Stripe account for the FastAPI app
Your Stripe account, test and live keys used by FastAPI, webhook endpoint, and Dashboard events. Stripe processing fees stay with Stripe.
Required FastAPI hosting
A host that can run uvicorn (or equivalent) and receive HTTPS POSTs from Stripe. A static-only site cannot host this FastAPI webhook path.

Delivery + security
FastAPI delivery and security practices
Estimated FastAPI delivery
Typical FastAPI Stripe integration is scoped after the FastAPI compatibility check. Timeline depends on your persistence layer and how clients call FastAPI.
Tested on FastAPI before handover
Test-mode PaymentIntents, webhook signatures, retries, and decline paths are exercised against the FastAPI app before we hand over.
Stripe secrets stay in FastAPI Settings
Secret keys and webhook signing secrets stay in server env. Clients only receive a publishable key or a short-lived client_secret.
Webhook verification before FastAPI writes
The FastAPI webhook route verifies Stripe signatures on the raw body before updating order or entitlement state.
No unverifiable FastAPI security claims
We do not claim PCI certification, zero fraud, or guaranteed approval rates. FastAPI does not store PAN. Card data is collected by Stripe Checkout or Elements on a client, not a custom FastAPI Form we persist.
FAQ
Frequently asked questions
What does Stripe Integration for FastAPI include?
Stripe Integration for FastAPI includes the official stripe Python SDK, a FastAPI APIRouter, a create-PaymentIntent endpoint, a webhook that calls construct_event on await request.body(), order-state updates on your existing store, tests against Stripe test events, and handover notes. You receive the FastAPI source in your project. Stripe fees and your Stripe account are separate.
Will you integrate Stripe into our existing FastAPI project?
Yes. Stripe Integration for FastAPI is built for a FastAPI app you already have. We fit routers, dependencies, and Settings into your current FastAPI project instead of shipping a separate demo app as the deliverable.
Does Stripe Integration for FastAPI collect card numbers in FastAPI?
No. FastAPI must not store PAN. Clients use Stripe Checkout or Elements. Stripe Integration for FastAPI owns server-side PaymentIntents, webhooks, and order writes. A custom FastAPI Form that posts raw card data is out of default scope.
Which Stripe package does Stripe Integration for FastAPI use?
Stripe Integration for FastAPI uses the official stripe Python library for PaymentIntents, Checkout Sessions, and Webhook.construct_event. We do not wrap FastAPI payments in an undocumented plugin unless you explicitly require one.
Why does Stripe Integration for FastAPI insist on request.body()?
stripe.Webhook.construct_event verifies the exact bytes Stripe signed. await request.json() parses and changes that body. Stripe Integration for FastAPI reads await request.body() on the webhook route. That is the usual FastAPI signature-check failure if you skip it.
Is Stripe Integration for FastAPI the same as Django?
No. FastAPI uses APIRouter, Depends, and pydantic-settings. Django views, urls.py, and the Django ORM are Stripe Integration for Django. We do not paste Django patterns into a FastAPI app.
Can Stripe Integration for FastAPI collect subscription payments?
FastAPI can create a PaymentIntent or Checkout Session and store the Stripe customer id. Recurring Stripe Billing products, customer portal, and invoice logic stay on the server. Subscription-heavy FastAPI work may need a Custom Quote.
Where do Stripe publishable and secret keys live in a FastAPI app?
The FastAPI process uses the secret key and webhook signing secret from Settings / environment variables. Clients only receive the publishable key. Stripe Integration for FastAPI does not put secret keys in Pydantic request models.
How do Stripe test mode and live mode work in FastAPI?
We implement Stripe Integration for FastAPI against Stripe test keys and test webhook events first. Going live is a documented key and endpoint cutover in your Stripe Dashboard and FastAPI env, not an add-on license activation.
How does Stripe Integration for FastAPI handle 3-D Secure / SCA?
FastAPI creates PaymentIntents that support SCA. The client completes 3-D Secure with Stripe.js or Checkout. FastAPI only fulfills after payment_intent.succeeded on the webhook, not after a browser redirect alone.
Are Stripe webhooks required for FastAPI checkout?
Yes for fulfillment after a FastAPI-created PaymentIntent or Checkout Session. A FastAPI 200 to the client is not the source of truth. The webhook route verifies signatures and then marks the order paid.
Can we keep SQLAlchemy with Stripe Integration for FastAPI?
Yes. Stripe Integration for FastAPI typically adds fields or a thin payment record next to your existing FastAPI order model instead of replacing SQLAlchemy or inventing a Django model.
Does the Stripe Integration for FastAPI price include a Stripe account or fees?
No. You create and own the Stripe account, API keys, and Stripe processing fees. The FastAPI add-on price is implementation into your FastAPI project, not a Bacodo payment license.
Does Stripe Integration for FastAPI block the event loop with sync stripe calls?
We scope this honestly during the FastAPI compatibility check. Blocking stripe calls inside async def are moved to a threadpool or we use Stripe’s async client where the pinned stripe release supports it. We do not pretend sync stripe is free in an async FastAPI route.
Can we customize Stripe receipts and metadata in FastAPI?
Yes. PaymentIntent or Checkout Session metadata, customer records, and the fields you persist after webhook confirmation are aligned to your existing FastAPI order model during Stripe Integration for FastAPI.
What FastAPI support is included after Stripe handover?
The FastAPI source is in your repo, so your team can maintain it. Included 30-day support covers technical questions and defects in the delivered Stripe Integration for FastAPI scope, not unrelated FastAPI feature work.
How are stripe or FastAPI updates handled after integration?
During the 30-day window we help with breakage in the delivered FastAPI integration caused by a documented Stripe API or stripe package change. Ongoing FastAPI upgrades after that are your maintenance, or Extended Technical Support if you buy it.
What if Stripe payments fail in a production FastAPI app?
We document how to read PaymentIntent status, Stripe Dashboard logs, and FastAPI webhook delivery. 30-day support includes troubleshooting signature failures (usually request.json() instead of request.body()), retries, and misconfigured keys for the delivered FastAPI flow.
Which FastAPI versions are compatible with Stripe Integration for FastAPI?
We confirm your FastAPI, Python, and pydantic v2 versions against the stripe release we pin at integration time. Older or heavily forked FastAPI runtimes may need extra scope.
What is 30-day support versus 6-month Extended Technical Support for Stripe Integration for FastAPI?
30 days after handover is included for the delivered FastAPI Stripe path. Extended Technical Support is optional at 20% of this FastAPI add-on price and covers six more months of technical help on that same FastAPI integration, not a new product build.
