Connect Navan to Hypamoon

Yes, with one catch. Navan has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.

Open

The check

Three questions about the API of Navan, answered from its own docs.

Public API docs
Yes. Read the docs
A key you create yourself
Yes. The guide starts with creating your API credentials in the Navan platform and choosing scopes such as Expense: Write. developer.navan.com
Versions or a changelog
Yes. Path versioning (v1); breaking changes get a new version, and release notes list changes. developer.navan.com
How it signs in
OAuth 2.0 client credentials from the Navan platform; EU accounts use the EU token address and region header.
Webhooks
Not confirmed.
Hosting
Cloud

Your own travel and expense overview on Navan, built around your teams.

  • Expense transactions and their status, from the scopes you choose.
  • AI that checks each expense against your policy and proposes the category, with a person approving.
  • A screen for budget owners and a weekly email for finance.

Ask your chat

Answers straight from your Navan data, in Claude or another chat with the full Hypamoon connection.

  • Which expenses from this week are missing a receipt?
  • Which teams spent most on travel this month?

On a schedule

Navan has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next.

  1. Every 15 minutes

    New expense transactions since the last check.

    AI decides

    AI suggests the category and flags expenses outside policy.

    Then

    After approval, the expense is updated in Navan.

    AI proposes, you approve

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Navan data.

  • For your team

    Budget owners see their team's travel and expense costs per month.

Navan stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Navan waits for your approval, one call at a time. How adapters work

Good to know

  • Navan signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Navan takes more work: ask your chat to check this first.
  • Audit log, activity and user endpoints are only for eligible companies; a 403 means you should contact your Navan account team.
