Free apps track a code. Roster runs the program.

Everything your ambassador and creator program needs, connected to Shopify

Built on Shopify's own discounts, orders and customers, with the tools to grow beyond them.

Codes and links

A unique Shopify discount code for every ambassador, plus Smart Links tracked from click to checkout. Bring your existing codes with you.

Leakproof codes

Single-use codes applied automatically when a shopper clicks an ambassador's link, so your discounts stay off coupon sites.

Accurate attribution

Order and refund updates keep results current, including subscription orders. Refunds adjust rewards automatically.

Results inside Shopify

Every referred order is tagged in Shopify, with the ambassador and code saved on the order, so your team sees it where they already work.

Product gifting

Your customers, connected

Roster brings in your recent Shopify customers and their order history, and tags ambassadors in Shopify for segments and perks.

Creator Discovery

Find and evaluate new creators on Instagram and TikTok, so your program isn't limited to people who already bought.

Partnership and Spark Ads

Get creator permission in Roster and run their best UGC as Meta partnership ads or TikTok Spark Ads.

Automated payments and taxes

Payouts run themselves every month through Venmo and PayPal, with W‑9, W‑8BEN and 1099s collected and filed for you.

Is Roster the right fit?

Worth knowing before you book.

$1M+ in revenue

Or roughly 10,000 customers. Below that, a free app is usually enough.

A product people post about

Apparel, outdoor, food, beauty and consumer goods work best.

Someone to own it

A few hours a week is realistic once the program is running.

Connects in minutes. Roster also supports other carts if you move later.

Shopify ambassador app FAQ

Do I need to edit my Shopify theme?

No. When you connect the Roster app, link tracking installs as a Shopify Web Pixel, so nobody touches your theme code.

How long does it take to connect Shopify?

A couple of minutes. A full Shopify admin approves the Roster app, and codes, links and order tracking are ready to use.

Can I keep my existing discount codes?

Yes. You can import the Shopify discount codes your ambassadors already use, and Roster creates new codes for everyone else.

How do you stop codes leaking to coupon sites?

Leakproof codes are single-use and are applied automatically when a shopper clicks an ambassador's link, so there is no reusable code to share.

Does Roster track subscription orders?

Yes. Recurring and subscription orders are tracked, and refunds adjust rewards automatically.

How are ambassadors rewarded?

With free product sent as a Shopify order, percent-off or fixed-amount discount codes, points and tiers, or cash through PayPal and Venmo. Automated Payments run payouts every month, with W‑9, W‑8BEN and 1099 tax documents collected and filed for you.

Can we work with creators, not just customers?

Yes. Start with the customers who already love your brand, then use Creator Discovery to find creators on Instagram and TikTok. Run their best UGC as Meta partnership ads or TikTok Spark Ads, with permission collected in Roster.

How is Roster different from Shopify Collabs or GoAffPro?

Those apps mostly track codes and links. Roster runs your whole ambassador and creator program: recruiting and Creator Discovery, campaigns and UGC, product gifting, points and tiers, leakproof codes, automated payments and taxes, partnership ads, and revenue tracked per ambassador, with flat pricing and no percentage-of-sales fees.
