Example for machine-to-machine implementation

[gregoriopellegrino]

Hi,
I'm trying to convert a Private Application to a Machine-to-Machine implementation, but I can't find how to implement it. Is there documentation or examples?

Thanks,
Gregorio

Hi @gregoriopellegrino , I am in the same situation. While waiting for them to implement the newly released custom connection authentication, this is my temporary solution. The idea basically is to pass an initial access token into the oauth2 credentials. Hope this helps.

Here's the example

from xero import Xero
from xero.auth import OAuth2Credentials
import requests

class CustomConnetionsOAuth2Credentails(OAuth2Credentials):

    def __init__(self, client_id, client_secret, tenant_id=None):
        token = requests.post('https://identity.xero.com/connect/token', 
            data={
                "grant_type": "client_credentials",
            },
            auth=(client_id, client_secret)).json()
        if tenant_id is None:
            # Get Default TenantID
            tenant_id = requests.get("https://api.xero.com/connections", 
                headers = {"Authorization": f"Bearer {token['access_token']}"}).json()[0]['tenantId']
        super().__init__(
            client_id=client_id, 
            client_secret=client_secret,
            token=token,
            tenant_id=tenant_id)


class MyXeroClient:

    def __init__(self):
        credentials = CustomConnetionsOAuth2Credentails(
            client_id=<client_id>, 
            client_secret=<client_secret>
        )
        self.xero = Xero(credentials)

    ....

we don't really need tenant id. we can get away with a dummy string.
