localstack-xero 0.1.0

Xero API emulator – LocalStack extension

xero-local

A lightweight local emulator for the Xero Accounting API, designed for development and testing without hitting the real Xero service.

Can be used standalone (Python or Docker) or as a LocalStack extension that starts automatically alongside LocalStack.

Supported endpoints

Resource	Operations
Contacts	list, get, create, update
Invoices	list, get, create, update
Payments	list, get, create, delete
CreditNotes	list, get, create, update
Connections	list (Identity API)
OAuth2 token	issue (any credentials accepted)

All data is stored in memory and reset on restart. A POST /_xero/reset endpoint is available to clear state between tests.

Quickstart

Python

pip install localstack-xero
xero-local          # starts on http://localhost:5001

Docker

docker run --rm -p 5001:5001 localstack/xero-local

Point your Xero client at http://localhost:5001 instead of https://api.xero.com.

LocalStack extension

localstack extensions install xero
localstack start

The emulator starts automatically with LocalStack and is reachable at http://xero.localhost.localstack.cloud:4566.

Set XERO_PORT (default 5001) or XERO_HOST to change the bind address.

Development

make install-dev   # install with test/lint deps
make test          # run the test suite (42 tests)
make run           # start the emulator locally
make lint          # ruff check
make format        # ruff format + autofix

Docker

make docker-build  # build image for host platform
make docker-run    # run on port 5001
make docker-buildx # build and push multi-arch (amd64 + arm64)

Configuration

Variable	Default	Description
XERO_PORT	5001	Port the emulator listens on
XERO_HOST	0.0.0.0	Bind address

CI

Pushes to main and semver tags (v*.*.*) trigger a GitHub Actions workflow that runs the test suite (Python 3.9 and 3.11) and builds and pushes a multi-arch image (linux/amd64, linux/arm64) to Docker Hub. Required secrets: DOCKERHUB_USERNAME, DOCKERHUB_TOKEN.
