Xero API Integration is the use of Application Programming Interface connections to link Xero's cloud-based accounting platform to other business applications — e-commerce platforms (Shopify, BigCommerce, Wix), CRM software (Salesforce), email marketing platforms (Constant Contact, Drip), and others — so that data flows automatically between systems in real time without manual export, formatting, and import steps. APIs allow programs to share data without exposing their underlying source code, which is what makes the connection both automated and secure: information moves between Xero and connected applications without human initiation, without file downloads, and without the security risk of exposing proprietary code.
Xero handles a wide range of small and mid-sized business operations — bill payment, expense claims, bank connections, invoicing, payroll, project tracking, and supplier and customer management. But Xero does not operate in isolation: most businesses using Xero also use e-commerce platforms, CRM software, and email marketing tools that hold equally important data. According to BOLD VAN, an API is what connects these systems — allowing Xero to share data with other applications automatically, so the same customer record, invoice, and inventory figure is current and accessible in every platform simultaneously, without anyone initiating a manual data transfer.
Quick Answer
An API (Application Programming Interface) is a connector that allows two software programs to share data automatically without exposing their underlying code. For Xero users, APIs connect Xero to e-commerce platforms (Shopify, BigCommerce, Wix — eliminating manual order and inventory imports), CRM platforms (Salesforce — giving customer service and accounting teams access to the same current client data), and email marketing tools (Constant Contact, Drip — automatically adding new Xero customers to email lists). Each connection enables automatic workflows: a new Shopify order triggers a Xero invoice, a new Xero invoice triggers a Salesforce opportunity — without any manual steps.
TL;DR
An API (Application Programming Interface) is a connector that allows two software programs to exchange data automatically without revealing their underlying source code to each other. Think of it as a bridge: on one side is Xero, on the other side are the e-commerce platforms, CRM systems, marketing tools, and other applications the business uses. The API carries data back and forth between them in real time, without requiring anyone to download, format, or import files manually. The security benefit is built in — because APIs work without exposing source code, both programs share only the data they have agreed to share, without either side gaining access to the other's underlying system.
Most small and mid-sized businesses use Xero alongside other essential platforms — a Shopify store for e-commerce, Salesforce for customer relationship management, Constant Contact for email marketing. Each platform holds valuable data. Without an API connection, that data stays siloed: getting information from Shopify into Xero requires someone to export it, format it, and import it manually — a process that is slow, error-prone, and always slightly out of date by the time it arrives.
An API eliminates every manual step in that process. The connection is established once, the data sharing rules are defined, and from that point forward the systems communicate automatically — the moment something changes in Shopify, Xero knows about it, and vice versa.
TL;DR
An API connection between Xero and an e-commerce platform — Shopify, BigCommerce, Wix, Shift4Shop, or any of the more than 100 shopping cart platforms available — eliminates the manual transfer of customer data, inventory numbers, and sales information from the online store into Xero. More importantly, it enables automatic trigger-based workflows: a new Shopify order automatically creates an invoice in Xero, which can in turn automatically trigger a Salesforce opportunity — creating a chain of automated actions across multiple systems from a single customer event.
TL;DR
Without an API connecting Xero to a CRM platform like Salesforce, accounting data and customer relationship data live in separate systems updated on different schedules — meaning the customer service team's view of a client and the accounting team's view of the same client may not match. The API eliminates this gap by pushing data between Xero and the CRM in real time: a customer service representative answering an invoice question sees exactly the same current invoice data the accounting team sees, eliminating the conflicting information that damages customer confidence.
The customer experience impact of disconnected systems is tangible. When two people from the same company give a customer conflicting information — one referencing an invoice amount, another referencing a different one from a system that hasn't been updated — the customer's reaction is predictable: the company doesn't have its information organized, and trust erodes. In a competitive market, that erosion translates directly to lost business.
An API connection between Xero and a CRM like Salesforce ensures that every team member — customer service, sales, and accounting — works from the same current data simultaneously. When a customer calls with an invoice question, the customer service representative can see the exact invoice the customer is referencing without putting them on hold to call accounting. The experience is seamless because the data is unified.
TL;DR
An API connection between Xero and email marketing platforms like Constant Contact, Drip, or Sendinblue automates the customer list management step that otherwise requires manual export from Xero and import into the email tool. When a new customer is added to Xero, the API automatically adds their contact information to the email marketing platform — ensuring that new customers receive onboarding communications, promotional emails, and other automated sequences without any manual list management required.
The same principle that makes the e-commerce and CRM connections valuable applies to email marketing: the data already exists in Xero, and the email platform needs that same data. Without an API, someone has to periodically export the Xero customer list, format it correctly for the email platform, and import it — a process that is always slightly stale by the time it is complete, and that creates opportunities for missed contacts, duplicate entries, and formatting errors.
With an API connection, the moment a new customer appears in Xero, their contact information flows directly into the email marketing platform. New customers receive the right communications automatically, without anyone managing the list transfer.

Schedule a Free DemoAn API (Application Programming Interface) is a general-purpose connector that allows two software programs to share data in real time — it is used across consumer apps, business software, and cloud platforms for any kind of data exchange. EDI (Electronic Data Interchange) is a specific, standardized format for exchanging structured business documents (purchase orders, invoices, advance ship notices) between trading partners according to defined compliance standards like X12 or EDIFACT. According to BOLD VAN, APIs and EDI are complementary rather than competing: APIs connect internal systems (Xero to Shopify, Xero to Salesforce) and enable real-time data flow, while EDI handles the standardized compliance document exchange with external trading partners. Most growing businesses need both.
Not in real time. Without an API, connecting Shopify data to Xero requires manual export from Shopify, formatting for Xero's import requirements, and manual import into Xero — a process that is time-consuming, error-prone, and always behind the current state of the Shopify store. An API connection eliminates all manual steps: data flows automatically between the two platforms in real time, and trigger-based workflows (new Shopify order → new Xero invoice) operate without human initiation.
Yes. APIs are designed specifically to share data between programs without exposing the underlying source code of either system. Xero's API uses OAuth authentication, meaning the connection is established through a secure credential exchange rather than through sharing login credentials or database access. The data shared through the API is limited to what both systems have agreed to exchange — neither system gains access to the other's underlying code or unrelated data.
Any e-commerce platform with its own API can connect to Xero through an API integration. This includes Shopify, BigCommerce, Wix, Shift4Shop (formerly 3dcart), WooCommerce, Magento, and more than 100 other shopping cart platforms. The connection enables automatic synchronization of customer data, order information, inventory numbers, and sales figures between the store and Xero's accounting system — eliminating manual import processes and keeping both systems current simultaneously.
Key Facts — Summary
An API (Application Programming Interface) is a connector that allows two software programs to share data automatically without exposing their underlying code. For Xero users, APIs enable three categories of integration: e-commerce platform connections (Shopify, BigCommerce, Wix — automatic order, customer, and inventory synchronization with trigger-based workflows), CRM platform connections (Salesforce — real-time data alignment between accounting and customer relationship management so all teams see the same current client information), and email marketing connections (Constant Contact, Drip — automatic customer list updates when new contacts are added to Xero).
API connections eliminate the manual download-format-import cycle that keeps systems out of sync, reduce errors from manual data entry, and enable automatic trigger-based workflows across connected platforms. For businesses that also require EDI compliance with retail trading partners, API integration with Xero ensures that order and invoice data flows between the accounting system and the EDI layer automatically — without requiring separate data entry in each system.
