MCP + API attribution

Affiliate programs for apps, marketplaces and social platforms.

Launch a program in minutes. Pay per signup or per paying subscriber, restrict by market, and measure every referral through your own API or MCP server.

Set the rules

Pay only for what counts

Signup, first payment, or one specific plan. Set a rate, a monthly cap, and how many months a subscription keeps earning.

Control access

Open or approval-based

Let anyone join, or review each applicant. Restrict campaigns to chosen markets and discount the users they bring.

Measure it

API, Stripe and MCP attribution

Report conversions from your own backend, connect Stripe and report nothing at all, or let an agent query results directly.

Pay for outcomes, not clicks.

$0.50
per new signup
Verified free account, one per user
$4.00
per new paying subscriber
Any plan, after the first invoice settles
$10.00
per specific plan
Reserved for your highest-value tier

Or keep paying for as long as they stay: set a campaign to pay its rate every month for up to twelve months, and it stops the moment the subscription cancels.

Two sides, one platform.

For founders and dev teams

Grow users by paying for results.

Decide what a signup or a paying subscriber is worth, prepay the budget so you never overspend, and let creators bring you customers while you ship. Integration is one POST from your backend — or nothing at all if you are on Stripe.

For creators and influencers

Browse programs, join in two clicks, and earn per signup, per subscriber, or every month for up to a year. Free to join, paid through Stripe, and backed by budgets the business already funded.

Three ways to connect.

Conversion API

Your backend tells us when a referred visitor signs up or pays.

POST /api/v1/conversions
Authorization: Bearer sk_live_…

{ "ref": "…",
  "event": "subscription.paid",
  "externalEventId": "evt_123" }

Stripe

Connect your Stripe account and write no code at all. We read your payments and your cancellations, so recurring commissions stop the moment a subscriber leaves.

MCP

Point an agent at our MCP server to read campaign performance, review applicants and report conversions in the same breath.

Common questions.

What is ShopSlash?

Affiliate program software for SaaS products, marketplaces and social platforms. Businesses create campaigns that pay per signup, per paying subscriber, or a recurring commission each month a subscription stays active. Affiliates join, get tracked links, and are paid through Stripe.

How does ShopSlash track referrals?

Affiliate links redirect through ShopSlash, which sets a signed referral token as a first-party cookie and appends it to the destination URL. You capture it at signup and report the conversion through the REST API, through your connected Stripe account, or through the MCP server.

What does it cost?

Businesses pay a monthly plan from $0 to $100, plus a 5% platform fee and card processing when they fund a campaign budget. Affiliates pay nothing, ever.

Do businesses pay affiliates in advance?

Businesses prepay their campaign budget before a campaign can go live, and affiliates are paid from that money. A commission is never accrued that the funded balance cannot cover.
