LogiSense
Add LogiSense to your product for your customers, and give your AI agents governed access to it.
Embed a LogiSense integration so usage measured in your product is rated and billed in the customer's own LogiSense account rather than in a spreadsheet somebody reconciles later. LogiSense is an API-first usage and subscription billing platform, so your product can post usage records, read the subscriptions and invoices that come out of rating, and react when a bill or a payment result lands. Writes are idempotent, which is the point in billing: a retry after a timeout must not charge twice. Each customer's rate plans, products and billing cycles are per-tenant configuration, and fastn owns the credentials, retries and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Post usage records from your product into a customer's LogiSense account so metered charges are rated from what actually happened.
Read a customer's subscriptions and invoices back so your product can show what a buyer will be charged without a second system.
React to a new invoice or a payment result with an event trigger so entitlement and dunning steps run immediately.
Support each customer's own products, rate plans and billing cycles as per-tenant configuration rather than code.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent explains an invoice line by tracing it back to the usage that was rated, reading only that tenant's data.
An agent answers a billing question from the customer's own subscription and invoice records within scoped permissions.
An agent flags accounts whose usage has moved outside their plan, with every read audited.
Example prompt
Why is this account's LogiSense invoice higher this month than last?
Set up LogiSense in 4 steps
- 01Enable the LogiSense connector in your fastn dashboard.
- 02Have each customer authorise their own LogiSense account so calls run under their credentials.
- 03Map the usage records, subscriptions and invoice fields your product uses, then enable triggers.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the LogiSense integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a LogiSense integration without building it. Your customers connect their own LogiSense account inside your product and work their orders, payments and customers there, with no per-customer code on your side.
- Handle the part that actually costs time: money and order state must never be double-applied, and reconciliation has to be possible. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a LogiSense update is not your on-call problem.
- One integration serves your product and your agents. The same governed LogiSense connection powers in-product features and gives AI agents scoped, audited access, so you keep commerce and payment records in step with your product without wiring it twice.

DocusignLogiSense integration FAQ
How do I add a LogiSense integration to my product?
Enable the LogiSense connector in your fastn dashboard, then let each customer authenticate their own LogiSense account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no LogiSense client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own LogiSense account?
Yes. Every connection is scoped to the individual customer, so each authorises their own LogiSense account and only ever sees their own orders, payments and customers. 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 LogiSense 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 explains an invoice line by tracing it back to the usage that was rated, reading only that tenant's data.
Who maintains the LogiSense integration?
fastn does. When LogiSense 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.
Is the LogiSense integration safe for payment and order writes?
Writes are idempotent, so a retry cannot double-charge or duplicate an order, and every call is logged per tenant so a transaction can be reconciled against the event that triggered it.
Can my product react to a new order, payment or refund immediately?
Yes, through event triggers, so fulfilment, entitlement or accounting steps run as soon as the event lands rather than on a nightly sync.
What can I build with the LogiSense integration?
A common starting point: post usage records from your product into a customer's LogiSense account so metered charges are rated from what actually happened. 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 LogiSense integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding LogiSense does not change your per-connector cost. You can start free with 3 connected accounts.
