Establishing the communication channel between the Xero and Web app:

The Xero API is a RESTful web service and used OAuth (V1.0) for authenticating the third-party applications.
However, Accounting API exposes accounting related functions of the main Xero application. Thus used for a variety of purposes such as creating invoices, credit notes, and getting journals, etc.,

Application Types:

Xero has three types of applications which can be used to connect to their API integration web services.

  • Private.
  • Public.
  • Partner application.

Private Application:

  • User or developer, can set up this app and also must have access to the organization.
  • It requires consumer key and also self-signed certificate to access organization data.
  • It has long-term access to the Xero organization.

Publish Applications:

  • The developer can set up this.
  • Authentication requires Xero Login and also token provided to the app.
  • Authentication token expires in 30 mins.

Partner Applications:

  • A developer can set up this.
  • It has long-term access to the Xero organization.
  • Used to connect many organizations of Xero.
  • It requires Xero login to allow API requests and also gives back the token with long-term access.
  • User/developer can create public application first and then make the partner application port request.

Sample code block to building oauth for Private applications:

def xero_api_authentication:
with open(os.path.join(settings.BASE_DIR,”path_to_pemkey/privatekey.pem”)) as keyfile:
rsa_key = keyfile.read()

oauth = OAuth1(
url = settings.XERO_API_ENDPOINT + api_url
return url, oauth

url, oauth = xero_api_authentication(“Items”)
response = requests.post(url=url, auth=oauth, data=xml_string, cert=None)

Data exchange between Xero and web app via API services:

Once the communication has been established between the Webapp and Xero, you can use the Xero respective API endpoint to GET the data from or to POST the data to Xero.
