Documentation

Provides a lightweight wrapper around calcinai/xero-php with additional Silverstripe support for authenication and connecting applications via oauth.

To setup register a Xero Application and define your clientId and clientSecret as environment variables.

XERO_CLIENT_ID='123'
XERO_CLIENT_SECRET='123'

Once those API keys are available, a new tab under the Settings admin will appear for connecting to Xero. Follow the prompts to link the selected account to your Silverstripe website.

Renewing the Access Token

Access tokens last 30 days, a scheduled queued job (RefreshXeroTokenJob) is provided which renews the access token on a regular basis.

Setting up the application in Xero

1. Head to https://developer.xero.com/app/manage/
2. Create a new Web App
3. Set the Redirect URI to be https://www.yoursite.com/connectXero

Note the connectXero endpoint in Silverstripe is restricted to ADMIN only users.

Interacting with the API

/** @var \XeroPHP\Application **/
$app = XeroFactory::singleton()->getApplication();

Integrating with the API is done via https://github.com/calcinai/xero-php. Consult that page for further information for creating invoices etc.
