NetLine
Add NetLine to your product for your customers, and give your AI agents governed access to it.
Embed a NetLine integration so leads your customers generate through content syndication land in your product rather than in a spreadsheet. NetLine runs cost-per-lead content syndication through its Portal, and each lead carries the contact and firmographic detail plus the answers to whatever custom questions the marketer put on the registration form, which is exactly why the shape of the data differs per campaign. Each customer connects their own Portal account, so lead pulls are scoped to their tenant and field mapping is configuration rather than code. fastn owns the credentials, pagination, throttling and API upkeep, and the same governed connection is what your AI agents read.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own NetLine Portal account so leads from their campaigns arrive in your product with no per-customer code.
Map the custom registration questions a campaign used to your own fields, per customer, so the answers are usable instead of a blob.
Route delivered leads onward to the CRM or marketing platform a customer already runs, using the same governed connection.
Read lead volume and campaign detail per tenant so your reporting reflects each marketer's own spend rather than an aggregate.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reviews the leads delivered for one campaign and flags the ones that match the customer's ideal profile, reading only their data.
An agent summarises which questions a lead answered before a rep makes contact, with every read audited.
An agent reports how lead quality shifted between two campaigns for a single tenant.

Set up NetLine in 4 steps
- 01Enable the NetLine connector in your fastn dashboard.
- 02Have each customer supply credentials for their own NetLine Portal account so pulls run under their access.
- 03Map the lead fields and campaign specific form questions to your own schema, per customer.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the NetLine integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a NetLine integration without building it. Your customers connect their own NetLine account inside your product and work their lookups, results and reports there, with no per-customer code on your side.
- Handle the part that actually costs time: these are metered read sources, so an uncached lookup on every page view burns the customer's allowance. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a NetLine update is not your on-call problem.
- One integration serves your product and your agents. The same governed NetLine connection powers in-product features and gives AI agents scoped, audited access, so you answer questions from an authoritative outside source without holding that data yourself without wiring it twice.

ShopifyNetLine integration FAQ
How do I add a NetLine integration to my product?
Enable the NetLine connector in your fastn dashboard, then let each customer authenticate their own NetLine account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no NetLine client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own NetLine account?
Yes. Every connection is scoped to the individual customer, so each authorises their own NetLine account and only ever sees their own lookups, results and reports. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this NetLine integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent reviews the leads delivered for one campaign and flags the ones that match the customer's ideal profile, reading only their data.
Who maintains the NetLine integration?
fastn does. When NetLine changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Whose credentials does a NetLine lookup run under?
Each customer's own. Quota and cost land on the customer that caused them rather than on a shared key you have to meter and re-bill, and one heavy customer cannot exhaust another's allowance.
How should NetLine results be cached?
Per tenant, with a window that matches how fast the underlying data actually moves. NetLine is a read source rather than a system of record, so the same query returns the same answer until the source changes, and caching is the difference between a sustainable integration and one that exhausts a customer's allowance on a busy page.
What can I build with the NetLine integration?
A common starting point: let each customer connect their own NetLine Portal account so leads from their campaigns arrive in your product with no per-customer code. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the NetLine integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding NetLine does not change your per-connector cost. You can start free with 3 connected accounts.
