Connect Fyle to Hypamoon

Yes, with one catch. Fyle 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.

The check

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

Public API docs
Yes. Sage Expense Management (formerly Fyle) publishes platform API docs with guides for internal and OAuth 2.0 applications. Read the docs
A key you create yourself
Yes. For your own organization you create an Internal application yourself; it runs on behalf of the user who created it. OAuth 2.0 apps are meant for partners. docs.fylehq.com
Versions or a changelog
Yes. The docs are kept per API version branch (v1). docs.fylehq.com
How it signs in
Access tokens valid for one hour, refreshed with a stored refresh token, for an internal application or an OAuth 2.0 app.
Webhooks
Not confirmed.

What you can build

Pull approved expenses and card transactions into your own bookkeeping flow, and ask your chat which expenses are missing a receipt.

Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work

Good to know

  • Fyle signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Fyle takes more work: ask your chat to check this first.
  • The app gets the roles of the user who authorized it, so an admin user gives access to the whole organization's expenses. GET calls support rich filtering.

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.

Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
