Your product on top. Our Amazon back end underneath.
Build your own client software on our Amazon Ads and Selling Partner infrastructure. Clients connect their Amazon accounts through links you create, land back in your product, and you hear about it by webhook. We run the connections, syncs and reports behind it.

The Amazon plumbing is the part nobody sees
You want to give clients your own software, not become a data-infrastructure company. The screens are the easy part. The back end is where the budget goes.
Build it yourself
- Get approved for the Amazon Ads API and SP-API, then build both OAuth flows
- Store and refresh every client's tokens, and catch revoked access
- Schedule report jobs, poll them, retry rate limits
- Reshape each report type into something your app can query
- Keep all of it working when Amazon changes things
Build on Marketplace Ad Pros
- Send a connect link; your client approves on Amazon
- We hold the tokens, refresh them and flag lost access
- Report syncs start as soon as a client connects, and keep running
- One REST API and MCP server across Ads and Seller Central
- Your developers build what makes your product different
What you get
Everything you need to onboard clients from inside your own product.
Links that return to you
Create a link with your own state. When the client finishes, they come back to your return URL with the result.
No stop on our site
Optionally skip our confirmation page, so clients go from your product straight to Amazon and back.
Webhooks
Signed events when a connect link completes or fails, a connection needs reauthorizing, access to a profile is revoked, or a brand is enabled or disabled at your brand limit.
A key per client
Limit a REST API key to one client's brands, so a bug or leaked key in one client's pipeline can't reach another's. Included on every paid plan.
The data
Amazon Ads, Seller Central and Vendor Central data through the REST API and MCP server, with exports of up to 100,000 rows per call.
Built on an API already in production
Partner Connect runs on the same REST API our customers already build on. In the 30 days to October 31, 2026:
8 of those accounts run 5 or more brands each, and 11 run over $50,000 a month in ad spend each.
Ad spend is a monthly run rate estimated from each brand's last 7 days, converted to US dollars. Our own staff accounts are excluded.
How It Works
Three steps, all available from the API.
Add Partner Connect
Add it to your paid subscription from Billing & Plans. $19/month, prorated.
Set your return URL and webhook
Tell us where clients land after connecting, whether to skip our confirmation page, and where to send events.
Send links, build your product
Create a connect link per client, send it, and build your screens on the data. Give each client's pipeline its own brand-limited key if you like.
Know what you're getting
- Amazon's consent screen names Marketplace Ad Pros as the app your client authorizes. Let your clients know to expect it.
- You build the screens your clients see. There's no branded copy of our web app, domain, email or billing.
- Brand-limited keys are for the REST API, not MCP. Account-wide endpoints (connect links, webhooks, connect settings, integrations, changesets, AMS and AMC) need a key without a brand limit, and Seller Central reports that cover a whole seller account need a key that covers every brand on that connection.
- One webhook endpoint per account. Deliveries are best effort and can arrive more than once or out of order, so confirm results through the API.
- Prefer to manage clients inside our app instead? See Marketplace Ad Pros for agencies.
Frequently Asked Questions
An add-on for agencies and software companies that build their own Amazon product for clients on Marketplace Ad Pros. Your clients connect their Amazon Ads, Seller Central or Vendor Central accounts through connect links you create, return to your product when they finish, and you're notified by webhook. We run the connections, data syncs and reports behind it.
$19 per month, added to a paid AI Connect or optimization subscription. It follows your subscription's billing: $5 per week on a weekly plan or $190 per year on an annual one. It isn't available during the two-week Launch period.
No. You build the screens your clients see, on top of our API. There's no branded copy of our web app, domain, email or billing. Your clients never need a Marketplace Ad Pros login.
Amazon's own consent screen shows Marketplace Ad Pros as the app your client authorizes, for Amazon Ads, Seller Central and Vendor Central. Before and after that screen, your client is in your product: you can skip our confirmation page so they go from your link straight to Amazon and back.
Yes, on every paid plan, with or without Partner Connect. When you create a REST API key you can limit it to one client's brands, so a bug or a leaked key in one client's pipeline can't read another client's data. Account-wide endpoints such as connect links, webhooks, integrations and changesets need a key without a brand limit.
New connect links stop returning to your URL and stop skipping our confirmation page, and webhooks stop. Your clients' connections keep working. Add it again to restore everything.
Ship your own Amazon software
Your clients stay in your product. We'll keep the Amazon plumbing running underneath.
