@duabalabs/sellub-client

Typed client for the Sellub commerce platform.

Sibling of @duabalabs/dps-client. Where DPS handles tenant identity / automation, Sellub handles commerce — catalog, checkout, orders, fulfillment, payments. This package wraps Sellub's REST + (later) GraphQL surfaces with typed helpers.

v0.4 — Shop API (NEW)

The ShopClient is a thin GraphQL wrapper around Sellub's Vendure Shop API at ${baseUrl}/shop-api. It manages session continuity for you (Vendure's vendure-auth-token is captured from response headers and re-attached on the next request).

import { createSellubClient } from "@duabalabs/sellub-client";

const sellub = createSellubClient({
  baseUrl: process.env.NEXT_PUBLIC_SELLUB_API_URL,        // default https://api.sellub.com
  publishableKey: process.env.NEXT_PUBLIC_SELLUB_PUBLISHABLE_KEY,
  channelToken: process.env.NEXT_PUBLIC_SELLUB_CHANNEL_TOKEN, // for Shop
});

const products = await sellub.shop.getProducts({ take: 12, term: "shoes" });
const order = await sellub.shop.addItemToOrder({
  productVariantId: products.items[0].id,
  quantity: 1,
});
await sellub.shop.setCustomerForOrder({
  emailAddress: "buyer@example.com",
  firstName: "Buyer",
  lastName: "Co",
});
await sellub.shop.transitionOrderToState({ state: "ArrangingPayment" });
const paid = await sellub.shop.addPaymentToOrder({ method: "paystack" });

For Shop-only callers, createShopClient(...) is exported directly. See the CHANGELOG for the full surface.

v0.3 — Money APIs

Three surfaces today, all hitting api.sellub.com/external-payments/* and authenticating with a publishable key (X-Sellub-Publishable-Key):

• externalPayments — one-off payments routed to a seller's Paystack subaccount (donations, simple buy buttons, embedded checkout).
• subscriptions — recurring billing on Paystack plans.
• invoices — hosted Paystack payment requests on behalf of a seller.

const sellub = createSellubClient({
  baseUrl: process.env.NEXT_PUBLIC_SELLUB_API_URL,        // default: https://api.sellub.com
  publishableKey: process.env.NEXT_PUBLIC_SELLUB_PUBLISHABLE_KEY,
});

One-off payments

const init = await sellub.externalPayments.initialize({
  channelSlug: "duabanti",
  email: "donor@example.com",
  amount: 5000,                    // pesewas — GHS 50.00
  customerName: "Kwame Mensah",
  description: "Donation to DuabaNti",
  callbackUrl: "https://duabanti.org/donate/thank-you",
  metadata: { source: "donate-modal" },
});

if (init.success && init.authorizationUrl) {
  window.location.href = init.authorizationUrl;
}

After Paystack redirects back, verify on your callback page:

const result = await sellub.externalPayments.verify(reference);
if (result.success && result.status === "success") {
  // unlock whatever the payment was for
}

Subscriptions

const sub = await sellub.subscriptions.start({
  channelSlug: "duabaconnect",
  email: "tenant@example.com",
  customerName: "Acme Ltd",
  plan: {
    name: "DuabaConnect Pro / monthly",
    amount: 15000,            // GHS 150.00
    interval: "monthly",
    currency: "GHS",
  },
  callbackUrl: "https://app.duabaconnect.com/billing/return",
  metadata: { tenantId: "acme" },
});

if (sub.success && sub.authorizationUrl) {
  window.location.href = sub.authorizationUrl;
}

Check status / cancel:

const status = await sellub.subscriptions.status(subscriptionCode);

await sellub.subscriptions.cancel({
  channelSlug: "duabaconnect",
  subscriptionCode,
  emailToken,
});

Invoices

const inv = await sellub.invoices.create({
  channelSlug: "duabatrade",
  email: "buyer@example.com",
  customerName: "Buyer Co.",
  currency: "GHS",
  dueDate: "2025-12-31",
  description: "Order #1234",
  lineItems: [
    { name: "Logistics", amount: 25000, quantity: 1 },
    { name: "Insurance", amount: 5000, quantity: 1 },
  ],
  sendNotification: true,
});

if (inv.success && inv.hostedUrl) {
  // share inv.hostedUrl with the buyer
}

const fetched = await sellub.invoices.get(inv.requestCode!);
