Leadspace
Add Leadspace to your product for your customers, and give your AI agents governed access to it.
Embed a Leadspace integration so your customers resolve and enrich their own company and contact data inside your product, using their own Leadspace account rather than a shared key. Which attributes matter differs per customer, so mapping is configuration instead of code. fastn handles per-customer credentials, retries, pagination and API upkeep, and bulk passes are throttled so they do not exhaust a customer's allowance.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own Leadspace account so matching and enrichment run on their plan.
Match a record your product already holds against Leadspace so duplicates are caught before they spread.
Read firmographic and audience attributes so your product scores and routes the way a customer does.
Keep bulk enrichment throttled per tenant so a large pass stays inside a customer's allowance.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent enriches an account before summarising it for a rep.
An agent checks whether two records resolve to the same company before merging anything.
Every call runs under the customer's own credentials and is logged per tenant.
Example prompt
Match these accounts against Leadspace and list the ones where the industry attribute disagrees with what we hold.
Set up Leadspace in 4 steps
- 01Open the Leadspace connector from your fastn dashboard.
- 02Have each customer authenticate their own Leadspace account.
- 03Map the company and contact attributes your product uses, then enable actions.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Leadspace integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Leadspace integration without building it. Your customers connect their own Leadspace 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 Leadspace update is not your on-call problem.
- One integration serves your product and your agents. The same governed Leadspace 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.

ShopifyLeadspace integration FAQ
How do I add a Leadspace integration to my product?
Enable the Leadspace connector in your fastn dashboard, then let each customer authenticate their own Leadspace account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Leadspace client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Leadspace account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Leadspace 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 Leadspace 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 enriches an account before summarising it for a rep.
Who maintains the Leadspace integration?
fastn does. When Leadspace 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 Leadspace 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 Leadspace results be cached?
Per tenant, with a window that matches how fast the underlying data actually moves. Leadspace 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 Leadspace integration?
A common starting point: connect their own Leadspace account so matching and enrichment run on their plan. 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 Leadspace integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Leadspace does not change your per-connector cost. You can start free with 3 connected accounts.
