Rydoo
Add Rydoo to your product for your customers, and give your AI agents governed access to it.
Rydoo captures expenses at the moment they happen, usually from a phone with a photograph of a receipt, and checks them against policy before anyone sees them. For an embedded Rydoo integration the interesting part is what has to be true before a claim can leave: an expense carries a category, a tax rate, a cost centre or project and the general ledger account finance will book it to, and mileage and per diem claims are calculated from country specific rates that differ per customer and change each year. Those are per tenant configuration, not code. Writes are idempotent, so a retry after a timeout does not submit the same claim twice, and every call is logged per tenant so a booked line can be traced to the event behind it. fastn keeps the credentials, the retries and the API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own Rydoo account so expenses your product already knows about are raised without anyone rekeying them.
Create an expense with its receipt, category, tax rate and cost centre so it arrives ready for approval rather than incomplete.
Read mileage and per diem claims calculated on that customer's own country rates, instead of assuming one rate table.
React when a claim is approved, rejected or exported to accounting, so your product's own steps follow the finance decision.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reports which claims are waiting on an approver and how long each has been sitting there.
An agent codes an expense to the right cost centre and general ledger account within governed permissions, idempotently and audited.
An agent explains why a claim failed a policy check by reading the expense itself rather than guessing.
Example prompt
Which Rydoo expense claims from last month are still unapproved, and what do they total by cost centre?
Set up Rydoo in 4 steps
- 01Enable the Rydoo connector in your fastn dashboard.
- 02Have each customer authorise their own Rydoo account so claims are raised under their credentials.
- 03Map the expense categories, tax rates, cost centres and general ledger accounts that customer uses, plus their mileage and per diem rate sets.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the Rydoo integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Rydoo integration without building it. Your customers connect their own Rydoo account inside your product and work their invoices, payments and vendors there, with no per-customer code on your side.
- Handle the part that actually costs time: financial writes must be idempotent and reconcilable, because a duplicate is an accounting problem rather than a bug. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Rydoo update is not your on-call problem.
- One integration serves your product and your agents. The same governed Rydoo connection powers in-product features and gives AI agents scoped, audited access, so you move financial records without hand-keying them between systems without wiring it twice.

AfterShipRydoo integration FAQ
How do I add a Rydoo integration to my product?
Enable the Rydoo connector in your fastn dashboard, then let each customer authenticate their own Rydoo account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Rydoo client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Rydoo account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Rydoo account and only ever sees their own invoices, payments and vendors. 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 Rydoo 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 reports which claims are waiting on an approver and how long each has been sitting there.
Who maintains the Rydoo integration?
fastn does. When Rydoo 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 Rydoo integration safe for financial writes?
Writes are idempotent, so a retry after a timeout does not post a document twice, and every call is logged per tenant so an entry can be traced back to the event that created it. That matters more in finance than anywhere else, because a duplicate is a number somebody has to explain.
Can it handle each customer's own chart of accounts?
Yes. ERP deployments are configured to the business, so account structures, required fields and fiscal calendars differ per customer. Those are mapped per tenant as configuration, not hard-coded.
What about Rydoo rate limits during a first import?
Backfills are throttled deliberately. ERP limits are often account-wide rather than per-integration, so an unthrottled import can exhaust a customer's allowance and disrupt their other integrations.
What can I build with the Rydoo integration?
A common starting point: let each customer connect their own Rydoo account so expenses your product already knows about are raised without anyone rekeying them. 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 Rydoo integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Rydoo does not change your per-connector cost. You can start free with 3 connected accounts.
