LeadMaster
Add LeadMaster to your product for your customers, and give your AI agents governed access to it.
Embed a LeadMaster integration so your customers work their own leads and contacts inside your product and your agents get governed access to them. CRM instances are customised, so field mapping is configuration per customer rather than code, and onboarding a customer with an unusual LeadMaster setup does not need a deploy on your side. fastn handles per-customer authentication, rate limits and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers sync their own LeadMaster leads and contacts into your product, mapped to their fields.
Create a lead from a form or signup captured in your product, so nothing is retyped.
Update lead status and log activities so the CRM reflects what happened in your product.
Read the pipeline so your product shows where each lead actually sits.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a lead and its recent activity before answering a question.
An agent creates or updates a lead within governed permissions, with each write audited.
An agent reacts to a status change and runs the next step of a workflow.
Example prompt
List leads assigned to this rep with no logged activity in the last 14 days.
Set up LeadMaster in 4 steps
- 01Open the LeadMaster connector from your fastn dashboard.
- 02Have each customer authenticate their own LeadMaster account.
- 03Map the leads, contacts and fields your product uses, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the LeadMaster integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a LeadMaster integration without building it. Your customers connect their own LeadMaster 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 LeadMaster update is not your on-call problem.
- One integration serves your product and your agents. The same governed LeadMaster 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.

How do I add a LeadMaster integration to my product?
Enable the LeadMaster connector in your fastn dashboard, then let each customer authenticate their own LeadMaster account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no LeadMaster client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own LeadMaster account?
Yes. Every connection is scoped to the individual customer, so each authorises their own LeadMaster 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 LeadMaster 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 recent activity before answering a question.
Who maintains the LeadMaster integration?
fastn does. When LeadMaster 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 LeadMaster 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 LeadMaster schema does not require a deploy on your side.
Can records sync both ways?
Yes. You can read from LeadMaster, write back to it, and react to changes through triggers, so a record updated in your product and a record updated in LeadMaster do not drift apart.
What can I build with the LeadMaster integration?
A common starting point: sync their own LeadMaster leads and contacts 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 LeadMaster integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding LeadMaster does not change your per-connector cost. You can start free with 3 connected accounts.
