Postman
Add Postman to your product for your customers, and give your AI agents governed access to it.
Embed a Postman integration so your product can work with the API collections a customer's engineers already maintain instead of asking them to redocument anything. Postman organises work into workspaces holding collections and requests, environments that supply variables, monitors that run collections on a schedule, and forks and pull requests when a collection is changed collaboratively. fastn handles per-customer credentials, retries and API upkeep, and delivers events as replayable triggers so a monitor result missed during downtime is not silently lost.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own Postman workspace so your product reads or publishes collections without anyone copying JSON around.
Create or update a collection from your product so generated requests stay in step with the API you actually expose.
Read monitor results per tenant so your product can show whether a customer's API checks are passing.
Manage environments per customer so variables stay in their workspace rather than in your config.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads a collection and its requests before it explains how to call an endpoint.
An agent creates or updates a collection or environment within governed permissions, with every action audited.
An agent reacts to a failed monitor run and gathers the request detail needed to diagnose it.
Example prompt
List monitors that failed in the last day and show which requests in the collection broke.
Set up Postman in 4 steps
- 01Open the Postman connector from your fastn dashboard.
- 02Have each customer connect their own Postman workspace with an API key.
- 03Select the collections, environments and monitors your product reads and writes, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Postman integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Postman integration without building it. Your customers connect their own Postman account inside your product and work their services, builds and deployments there, with no per-customer code on your side.
- Handle the part that actually costs time: these systems emit a lot of webhooks, and replay after downtime has to be handled. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Postman update is not your on-call problem.
- One integration serves your product and your agents. The same governed Postman connection powers in-product features and gives AI agents scoped, audited access, so you connect engineering activity to the rest of the business without wiring it twice.

PostgreSQLPostman integration FAQ
How do I add a Postman integration to my product?
Enable the Postman connector in your fastn dashboard, then let each customer authenticate their own Postman account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Postman client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Postman account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Postman account and only ever sees their own services, builds and deployments. 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 Postman 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 collection and its requests before it explains how to call an endpoint.
Who maintains the Postman integration?
fastn does. When Postman 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.
Can I react to Postman events in real time?
Yes, through event triggers. Events are delivered per tenant and can be replayed after an outage, so a webhook missed during downtime is not silently lost.
Can an agent open or update items in Postman?
Yes, within scoped permissions, and every action is audited so an agent's changes are attributable.
What can I build with the Postman integration?
A common starting point: connect their own Postman workspace so your product reads or publishes collections without anyone copying JSON around. 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 Postman integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Postman does not change your per-connector cost. You can start free with 3 connected accounts.
