When the Xero App Store Doesn't Have Your App
Xero's marketplace covers a lot of common software. But if your system isn't there, the app only does half the job, or you run software built just for your business, you need an integration written directly against the Xero API.
If you're looking for a Xero integration developer, this is the work we do: secure, authorised connections that create and read records in Xero on your behalf, follow your chart of accounts and tax codes, and are designed to keep running as your volumes grow.
What the Xero API Covers
Almost everything you can do in Xero by hand can be done through the API.
Invoices & credit notes
Bills & purchase orders
Payments
Contacts
Journals & bank
Reports
What Matters When Building on Xero
The details that separate an integration that works on day one from one that keeps working.
Authorisation per organisation
Each Xero organisation authorises the connection, and access tokens refresh automatically. One integration can serve several organisations — useful for groups of companies.
Rate limits
Xero limits how many API calls each organisation can make per minute and per day. We batch and queue requests so busy periods don’t cause failures.
Changes in Xero
Some record changes can be pushed to the integration as they happen; others are picked up by checking what’s changed since the last sync.
Lock dates and periods
Records dated into a locked period are rejected by Xero. We catch these and route them for review instead of letting them disappear.
Tax and tracking
Amounts can be tax-inclusive or exclusive, and Xero allows two active tracking categories. Both are mapped deliberately so reports come out right.
No duplicates
Each record carries a reference to its source, so re-running a sync updates instead of duplicating.
How we design, test and hand over every integration is covered on our Xero & MYOB integration page.
