Does SapphireOne have an API?

SapphireOne offers no public REST API. What it does document publicly is Sapphire Gateway II — an administrator-run import/export utility that takes tab-delimited files in template layouts, not an API a card platform can connect to. Vergo works with that reality: custom-built CSV exports matched to the import format SapphireOne expects, so coded card transactions load through the imports the system already supports.

Does SapphireOne have a public API?

Not in the sense most buyers mean. SapphireOne does not offer a public REST API that third-party platforms can connect to. What SapphireOne does document publicly is Sapphire Gateway II — a controlled data-entry and import utility that accepts tab-delimited files (and TCP command import) in defined template layouts. Gateway II is an administrator-run import/export tool, not an API: a person at the SapphireOne end runs the import, and the transaction table syntax is not publicly enumerated in full. In practice, SapphireOne integrations are built bespoke at implementation.

What does that mean for expense automation?

It means no card platform can post transactions into SapphireOne live. Anything arriving in SapphireOne from outside comes in as a file an administrator imports — through Gateway II or the system's standard import routines. The automation question is therefore not "can it sync?" (it can't, in the API sense) but "how clean is the file when it arrives, and how much work happened by hand before it existed?"

How does Vergo work with SapphireOne?

Vergo does the expensive part upstream and delivers the file. Cardholders code each card transaction to the right accounts, jobs, or departments in Vergo when they spend, capture the receipt on their phone, and finance approves in Vergo. Vergo then provides custom-built CSV exports matched to the import format SapphireOne expects, so your administrator imports a coded, approved, receipt-backed batch rather than keying entries.

To be precise: this is a file import workflow, not an API sync, and nothing posts into SapphireOne automatically. The gain is that the import file is finished data — allocations made by the people who spent, confirmed in approval — so the SapphireOne step is load-and-review.

Isn't Gateway II enough on its own?

Gateway II handles the loading; it does not create the data. Someone still has to produce a correctly laid-out file with every transaction coded and every receipt accounted for. That preparation — coding, matching, approving — is the work Vergo automates. Gateway II's documented, template-driven import is actually what makes SapphireOne a good candidate for this approach: the target format is defined, so a matched export can be built to it.

What should SapphireOne users ask expense vendors?

Ask whether their "integration" is an API connection or a file. SapphireOne publishes no public REST API, so the honest answer is a file — and the useful comparison between vendors is what state that file is in. Coded at the point of spend or coded by your team afterward; receipts attached or receipts chased; a layout matched to SapphireOne's import or a generic export someone has to rework.

Does SapphireOne have a REST API?

No. SapphireOne publishes no public REST API. Its documented external interface is Sapphire Gateway II, an administrator-run import/export utility using tab-delimited template files.

What is Sapphire Gateway II?

A controlled data-entry and import tool built into SapphireOne that loads tab-delimited files in defined layouts. It is run by an administrator inside the system — it is not an API a platform can connect to.

How does Vergo get card transactions into SapphireOne?

Vergo provides custom-built CSV exports matched to the import format SapphireOne expects. Transactions are coded, receipt-matched, and approved in Vergo before the file is generated.

Is this a live sync?

No — transactions appear in SapphireOne when your administrator runs the import, on your own cadence. For a system without a public API, a clean scheduled import is the working automation path.
