Xero API Integration - How to get tenant id ?

You can use the below code

var accessToken = "your_access_token";
var apiUrl = "https://api.xero.com/connections";

using (var httpClient = new HttpClient())
{
    httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);

    var response = await httpClient.GetAsync(apiUrl);

    if (response.IsSuccessStatusCode)
    {
        var jsonResponse = await response.Content.ReadAsStringAsync();

        // Parse the JSON response to get the tenant ID
        // The structure of the JSON response may vary based on Xero API version
        // Extract the tenant ID based on your specific API version and response structure
    }
    else
    {
        // Handle error
        var errorMessage = await response.Content.ReadAsStringAsync();
        Console.WriteLine($"Error: {errorMessage}");
    }
}

To retrieve the tenant ID for your demo company in the Xero portal, you can follow these steps:

1. Make a GET request to the /connections endpoint of the Xero API using the authorization code you obtained from Postman. This endpoint will provide you with a list of connections associated with your account.

2. Look for the connection that corresponds to your demo company. Each connection will have a unique tenantId property.

3. Retrieve the tenantId value from the connection object. This is your tenant ID.

Here's an example of how you can achieve this using the Xero API SDK in Python:

import requests
import json

authorization_code = "YOUR_AUTHORIZATION_CODE"
client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"

# Exchange authorization code for access token
token_url = "https://identity.xero.com/connect/token"
payload = {
    "grant_type": "authorization_code",
    "code": authorization_code,
    "client_id": client_id,
    "client_secret": client_secret,
    "redirect_uri": "YOUR_REDIRECT_URI"
}
response = requests.post(token_url, data=payload)
access_token = response.json()["access_token"]

# Make a GET request to retrieve connections
connections_url = "https://api.xero.com/connections"
headers = {
    "Authorization": f"Bearer {access_token}",
    "Content-Type": "application/json"
}
response = requests.get(connections_url, headers=headers)
connections = response.json()

# Find the connection for your demo company
demo_company = None
for connection in connections:
    if connection["tenantType"] == "ORGANISATION":
        demo_company = connection
        break

# Retrieve the tenant ID
tenant_id = demo_company["tenantId"]
print(f"Tenant ID: {tenant_id}")

By following these steps and making the appropriate API calls, you should be able to retrieve the tenant ID for your demo company in the Xero portal.
