LeadSquared
Add LeadSquared to your product for your customers, and give your AI agents governed access to it.
Embed a LeadSquared integration so your customers work their own leads and sales activity inside your product instead of switching tools. LeadSquared accounts are heavily customised, so lead fields, activity types and stages are mapped per tenant as configuration rather than code. fastn handles per-customer authentication, rate limits, pagination and API upkeep, so you support the long tail of setups without an integration per customer.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers sync their own LeadSquared leads and opportunities into your product, mapped to their fields.
Create a lead and post an activity when something happens in your product, so the CRM stays current.
Create or update tasks so a rep's follow-up lands where they already work.
Trigger your product when a lead stage or owner changes, rather than polling for it.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a lead and its activity history before drafting a follow-up.
An agent logs an activity or updates a lead within governed permissions, with each write audited.
An agent reacts to a stage change and runs the next step of a workflow.
Example prompt
Show leads created this week with no activity logged, grouped by owner.

Why teams use the LeadSquared integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a LeadSquared integration without building it. Your customers connect their own LeadSquared account inside your product and work their accounts, contacts and opportunities there, with no per-customer code on your side.
- Handle the part that actually costs time: every CRM instance is customised, so standard objects are never the whole story. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a LeadSquared update is not your on-call problem.
- One integration serves your product and your agents. The same governed LeadSquared connection powers in-product features and gives AI agents scoped, audited access, so you keep customer records aligned between your product and the CRM each customer already runs without wiring it twice.

Google AdsLeadSquared integration FAQ
How do I add a LeadSquared integration to my product?
Enable the LeadSquared connector in your fastn dashboard, then let each customer authenticate their own LeadSquared account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no LeadSquared client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own LeadSquared account?
Yes. Every connection is scoped to the individual customer, so each authorises their own LeadSquared account and only ever sees their own accounts, contacts and opportunities. 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 LeadSquared 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 reads a lead and its activity history before drafting a follow-up.
Who maintains the LeadSquared integration?
fastn does. When LeadSquared 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.
Does the LeadSquared integration support custom fields and custom objects?
Yes. CRM instances are heavily customised, so field and object mapping is configuration rather than code. Each customer maps their own fields during setup, which means onboarding a customer with an unusual LeadSquared schema does not require a deploy on your side.
Can records sync both ways?
Yes. You can read from LeadSquared, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in LeadSquared do not drift apart.
What can I build with the LeadSquared integration?
A common starting point: sync their own LeadSquared leads and opportunities into your product, mapped to their fields. 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 LeadSquared integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding LeadSquared does not change your per-connector cost. You can start free with 3 connected accounts.
