How to Sell eSIMs on Shopify in 2026: 3 Ways, From No Code to API

Q: How do I stop duplicate eSIMs when Shopify retries a webhook?

Send an Idempotency-Key with every order request, built from the Shopify order and line item IDs. The TripoSIM Partner API returns the same order for a repeated key instead of creating a new one.

Quick Answer

You can sell travel eSIMs on Shopify in three ways, from no code to fully automatic. The fastest is a referral link: you add eSIM plans to your store or blog and earn a commission on every sale, with no stock and no support work. The second is manual fulfilment: you sell eSIMs as digital products and send each QR code from a partner dashboard. The third is an API integration: when a Shopify order is paid, your app orders the eSIM through an eSIM API and emails the QR code to your customer in seconds, under your brand. Whatever you choose, list eSIMs as digital products with no shipping, show the destination and data clearly, and point buyers to a compatibility check before they pay.

Travel eSIMs are a natural add-on for many Shopify stores: travel gear, luggage, phone accessories, travel guides, tour operators and expat services. The product is digital, delivery is instant and customers buy again for every trip. This guide explains the three ways to add eSIMs to a Shopify store, how an API integration works step by step, and what to check before you launch.

Before you start

There is no official TripoSIM app in the Shopify App Store. The options below use a referral link, a partner account, or your own small app that connects Shopify to the TripoSIM Partner API. If you are not a developer, start with option 1 or 2.

Key facts

eSIMs are digital products. In Shopify, set them as products that do not require shipping.
Three models: referral link (commission, no stock), manual fulfilment (you buy at partner prices and send the QR code), API integration (automatic delivery).
With an API integration, delivery takes seconds: the order is created when Shopify confirms payment, and your customer receives the QR code by email.
Use idempotency keys: the TripoSIM Partner API requires an `Idempotency-Key` header on production orders and top-ups, so a retried webhook never creates a second eSIM.
Test first: the Partner API has a sandbox, so you can build and test the whole flow without spending money.
Compliance: follow sanctions and consumer rules in the countries where you sell, and do not sell to destinations your supplier does not support.

Three ways to sell eSIMs on Shopify

Option	How it works	Best for	Effort
1. Referral link	Add links or buttons to eSIM plans; customers buy on the eSIM provider's site and you earn a commission	Blogs, travel creators, stores starting out	Minutes, no code
2. Manual fulfilment	Sell eSIM products in your store, then order each eSIM in your partner dashboard and email the QR code	Small volumes, testing demand	Low, but manual for each order
3. API integration	A small app receives Shopify's paid-order webhook, orders the eSIM through the API and emails the QR code	Stores with regular orders who want their own brand	A few days of development

Option 1: referral link

This is the simplest way to start. With the TripoSIM Ambassador program, you get your own link and QR code, add them to your product pages, blog posts or order confirmation emails, and earn a commission on sales from your link. TripoSIM handles payment, delivery and customer support. Read more in our guide to earning money by sharing travel eSIMs.

Option 2: manual fulfilment

You create eSIM products in Shopify, for example "Japan eSIM, 10 GB, 30 days", and set your own retail price. When an order arrives, you buy the eSIM in your partner dashboard from your prepaid balance and send the QR code to your customer. It works well for a few orders a week and lets you test which destinations sell. Become a reseller to get partner prices.

Option 3: API integration

For regular orders, automate delivery with the TripoSIM Partner API. Your customer pays, and a few seconds later they receive their eSIM by email, with no manual work. The next section explains how it works.

How an API integration works

Create a partner account and get your API credentials. Build and test in the sandbox first.
Map each Shopify product or variant to a TripoSIM package ID from the catalog API, and keep your retail prices in Shopify.
Subscribe your app to Shopify's paid-order webhook and verify each webhook's signature before you trust it.
For each eSIM line, create an order with the Partner API. Send an `Idempotency-Key` built from the Shopify order and line item IDs, and your Shopify order number as the external reference.
Email the install details from the API response (QR code, SM-DP+ address and activation code) to your customer, then mark the Shopify order as fulfilled.
Subscribe to TripoSIM webhooks, such as order.completed, order.failed, esim.activated, esim.depleted and wallet.low_balance, to handle late deliveries, usage alerts and a low balance.

A few details make the difference between a demo and a reliable store:

Retries are normal. Shopify can send the same webhook more than once. The idempotency key makes a repeated request return the same order instead of buying a second eSIM.
Some orders take a little longer. If an order is still pending, wait for the order.completed webhook (or check the order later) before you email the customer.
Keep a low-balance alert. API orders are paid from a prepaid balance, so top it up before it runs out, or use the wallet.low_balance webhook.
Offer top-ups. Customers who run out of data can buy more for the same eSIM, which is a second sale for you.
Verify TripoSIM webhooks too: each webhook is signed, so check the signature before you act on it.

What to put on your eSIM product pages

Clear product pages reduce refunds and support emails:

Destination and coverage: the country or region, and the list of countries for regional plans.
Data and validity: for example 10 GB for 30 days, or the daily full-speed amount for unlimited plans.
Data only: say clearly that the eSIM gives mobile data, not a phone number for calls and SMS.
Compatibility: link to a phone compatibility check and remind buyers that the phone must not be locked to a carrier.
When the plan starts: most plans start when the eSIM first connects at the destination, so customers can install it before they travel.
Install once: explain that the QR code is usually for one installation, so it should not be scanned on two phones.

Pricing and margins

With a partner account, you buy at partner prices and set your own retail prices. TripoSIM partner tiers give a discount on the retail price that grows with your volume: Starter, Professional and Enterprise. Many stores price eSIMs close to the market price and make extra profit from top-ups and repeat buyers. See the reseller program for the current tiers.

Frequently asked questions

Is there a Shopify app for selling eSIMs?

There is no official TripoSIM app in the Shopify App Store. You can sell with a referral link, with manual fulfilment from a partner dashboard, or with your own small app that connects Shopify to the TripoSIM Partner API.

Do I need to hold stock to sell eSIMs?

No. eSIMs are created when they are ordered. With a referral link you never handle the product, and with the API each eSIM is ordered when your customer pays.

How fast can customers receive their eSIM?

With an API integration, usually within seconds of payment. With manual fulfilment, it depends on how quickly you process each order.

How do I stop duplicate eSIMs when Shopify retries a webhook?

Send an `Idempotency-Key` with every order request, built from the Shopify order and line item IDs. The TripoSIM Partner API returns the same order for a repeated key instead of creating a new one.

Can I sell eSIMs under my own brand?

Yes. With an API integration, your store sends the eSIM email under your brand. Our guide to affiliate, reseller and white-label models compares the options.

Can I test without paying for real eSIMs?

Yes. The TripoSIM Partner API has a sandbox where you can create test orders and simulate events before you go live.

The bottom line

Start with what fits your store today: a referral link if you want zero work, manual fulfilment to test demand, or an API integration for automatic delivery under your brand. Build in the sandbox, use idempotency keys, verify every webhook, and write clear product pages with a compatibility link. When you are ready, apply for the reseller program or explore the Partner API.
