Build Your Billing Page

Software applications typically ship with a billing page. This allows customers to change plan, cancel subscription and view their usage.

Your Autumn configuration is in autumn.config.ts. If it doesn't exist, run npx atmn init to log in and generate the file.

Step 1: Detect Integration Type

Check if the codebase already has Autumn set up:

  • If there's an AutumnProvider and autumnHandler mounted: Path A: React
  • If there's just an Autumn client initialized: Path B: Backend SDK

Before implementing:

  1. Tell the user which path you'll follow before proceeding.
  2. Tell them you will be building billing page components, and ask for any guidance or input.

Active Plans

Display the plan the user is currently on. Users can have multiple active subscriptions and purchases (e.g., main plan and add-ons).

  • subscriptions - Free and paid recurring plans
  • purchases - One-off plans (e.g., credit top-ups)

React

import { useCustomer } from "autumn-js/react";

const { data: customer } = useCustomer();

const active = customer?.subscriptions.filter(
  (sub) => sub.status === "active"
);

console.log(active?.map((sub) => sub.planId).join(", "));

TypeScript

import { Autumn } from "autumn-js";

const autumn = new Autumn({ secretKey: "am_sk_test_xxx" });

const customer = await autumn.customers.getOrCreate({
  customerId: "user_123",
});

const active = customer.subscriptions?.filter(
  (sub) => sub.status === "active"
);

console.log(active?.map((sub) => sub.planId).join(", "));

Python

from autumn_sdk import Autumn

autumn = Autumn("am_sk_test_xxx")

customer = await autumn.customers.get_or_create(
    customer_id="user_123"
)

active = [s for s in customer.subscriptions if s.status == "active"]
print([s.plan_id for s in active])

Usage Balances

Metered features have granted, usage, and remaining fields. Use these to display current usage and remaining balance.

React

import { useCustomer } from "autumn-js/react";

const { data: customer, refetch } = useCustomer();

const messages = customer?.balances.messages;

console.log(\`\${messages?.remaining} / \${messages?.granted}\`);

// After tracking usage or changing plans, call refetch() to update balances
await refetch();

TypeScript

const customer = await autumn.customers.getOrCreate({
  customerId: "user_123",
});

const messages = customer.balances?.messages;
console.log(\`\${messages?.remaining} / \${messages?.granted}\`);

Python

customer = await autumn.customers.get_or_create(
    customer_id="user_123"
)

messages = customer.balances.get("messages")
print(f"{messages.remaining} / {messages.granted}")

Customer Eligibility

When building a pricing page, you need to know what each plan means for the current customer -- is it an upgrade, a downgrade, or their current plan? Is a free trial available?

Pass a customerId when listing plans and each plan will include a customerEligibility object:

  • attachAction -- What happens when this plan is attached: "activate", "upgrade", "downgrade", "purchase", or "none"
  • status -- The customer's current relationship to this plan: "active", "scheduled", or undefined if none
  • trialAvailable -- Whether the customer is eligible for the plan's free trial

React

import { useListPlans, useCustomer } from "autumn-js/react";

const labels = {
  activate: "Subscribe",
  upgrade: "Upgrade",
  downgrade: "Downgrade",
  purchase: "Purchase",
};

const getLabel = (eligibility) => {

  if (eligibility?.attachAction === "none") {
    return eligibility.status === "scheduled" ? "Plan Scheduled" : "Current plan";
  }

  if (labels[eligibility?.attachAction]) {
    return labels[eligibility.attachAction];
  }

  return "Get started";
};

export default function PricingPage() {
  const { data: plans } = useListPlans();
  const { attach } = useCustomer();

  return plans?.map((plan) => (
    <button
      key={plan.id}
      disabled={plan.customerEligibility?.attachAction === "none"}
      onClick={() => attach({ planId: plan.id, redirectMode: "always" })}
    >
      {getLabel(plan.customerEligibility)}
    </button>
  ));
}

The React useListPlans hook automatically includes customer context from AutumnProvider, so customerEligibility is populated on every plan without extra configuration.

TypeScript

const { list: plans } = await autumn.plans.list({
  customerId: "user_123",
});

for (const plan of plans) {
  console.log(plan.name, plan.customerEligibility?.attachAction);
  // e.g. "Free" "downgrade", "Pro" "none", "Enterprise" "upgrade"
}

Python

plans = await autumn.plans.list(customer_id="user_123")

for plan in plans.list:
    print(plan.name, plan.customer_eligibility.attach_action)

Switching Plans

Use attach to switch between plans. This handles upgrades, downgrades, and new subscriptions.

React

import { useCustomer } from "autumn-js/react";

export default function UpgradeButton() {
  const { attach } = useCustomer();

  return (
    <button onClick={() => attach({ planId: "pro" })}>
      Upgrade to Pro
    </button>
  );
}

TypeScript

const response = await autumn.billing.attach({
  customerId: "user_123",
  planId: "pro",
});

redirect(response.paymentUrl);

Python

response = await autumn.billing.attach(
    customer_id="user_123",
    plan_id="pro",
)
# Redirect to response.payment_url

Cancelling a Plan

Cancel a subscription using billing.update with a cancelAction.

React

import { useCustomer } from "autumn-js/react";

const { updateSubscription } = useCustomer();

// Cancel at end of billing cycle
await updateSubscription({
  planId: "pro",
  cancelAction: "cancel_end_of_cycle",
});

TypeScript

await autumn.billing.update({
  customerId: "user_123",
  planId: "pro",
  cancelAction: "cancel_end_of_cycle",
});

Python

await autumn.billing.update(
    customer_id="user_123",
    plan_id="pro",
    cancel_action="cancel_end_of_cycle",
)

Uncancelling a Plan

If a subscription has a pending cancellation (when canceledAt is not null while the subscription is still active), you can reverse it:

React

import { useCustomer } from "autumn-js/react";

export default function BillingPage() {
  const { data: customer, updateSubscription } = useCustomer();

  const cancellingSub = customer?.subscriptions.find(
    (sub) => sub.status === "active" && sub.canceledAt !== null
  );

  return cancellingSub ? (
    <button onClick={() => updateSubscription({
      planId: cancellingSub.planId,
      cancelAction: "uncancel"
    })}>
      Keep plan
    </button>
  ) : null;
}

TypeScript

const customer = await autumn.customers.getOrCreate({
  customerId: "user_123",
});

const cancellingSub = customer.subscriptions?.find(
  (sub) => sub.status === "active" && sub.canceledAt !== null
);

if (cancellingSub) {
  await autumn.billing.update({
    customerId: "user_123",
    planId: cancellingSub.planId,
    cancelAction: "uncancel",
  });
}

Python

customer = await autumn.customers.get_or_create(
    customer_id="user_123"
)

cancelling_sub = next(
    (s for s in customer.subscriptions
     if s.status == "active" and s.canceled_at is not None),
    None,
)

if cancelling_sub:
    await autumn.billing.update(
        customer_id="user_123",
        plan_id=cancelling_sub.plan_id,
        cancel_action="uncancel",
    )

Stripe Billing Portal

The Stripe billing portal lets users manage their payment method, view past invoices, and cancel their plan. Enable the billing portal in your Stripe settings first.

React

import { useCustomer } from "autumn-js/react";

const { openCustomerPortal } = useCustomer();

await openCustomerPortal({
  returnUrl: "https://your-app.com/billing"
});

TypeScript

const { url } = await autumn.billing.openCustomerPortal({
  customerId: "user_123",
  returnUrl: "https://your-app.com/billing",
});

redirect(url);

Python

response = await autumn.billing.open_customer_portal(
    customer_id="user_123",
    return_url="https://your-app.com/billing",
)
# Redirect to response.url

Usage History Chart

Autumn provides aggregate time series queries for usage data. Pass the response to a charting library like Recharts.

React

import { useAggregateEvents } from "autumn-js/react";

const { list, total } = useAggregateEvents({
  featureId: "messages",
  range: "30d",
});

// list: [{ period: 1234567890, values: { messages: 42 } }, ...]
// total: { messages: { count: 100, sum: 500 } }

TypeScript

const { list, total } = await autumn.events.aggregate({
  customerId: "user_123",
  featureId: "messages",
  range: "30d",
});

Python

response = await autumn.events.aggregate(
    customer_id="user_123",
    feature_id="messages",
    range="30d",
)
# response.list, response.total

Prepaid Top-ups Reference

Let customers purchase prepaid packages and top-ups. If a user hits a usage limit, they may be willing to purchase a top-up. These are typically one-time purchases that grant a fixed amount of usage.

React

import { useCustomer } from "autumn-js/react";

export default function TopUpButton() {
  const { attach } = useCustomer();

  return (
    <button
      onClick={async () => {
        await attach({
          planId: "top_up",
          options: [{
            featureId: "messages",
            quantity: 200,
          }],
        });
      }}
    >
      Buy More Messages
    </button>
  );
}

TypeScript

const response = await autumn.billing.attach({
  customerId: "user_or_org_id_from_auth",
  planId: "top_up",
  options: [{
    featureId: "messages",
    quantity: 200,
  }],
});

if (response.paymentUrl) {
  redirect(response.paymentUrl);
}

Python

response = await autumn.billing.attach(
    customer_id="user_or_org_id_from_auth",
    plan_id="top_up",
    options=[{
        "feature_id": "messages",
        "quantity": 200,
    }],
)

Important Notes

  • This handles all upgrades, downgrades, renewals, and uncancellations automatically
  • Plan IDs come from the Autumn configuration
  • Your Autumn configuration is in autumn.config.ts in your project root
