Use Dash to Build Web Apps on ZohoDesk Data via CData Connect AI

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData Connect AI Python SDK, the pandas module, and the Dash framework, you can build ZohoDesk-connected web applications for ZohoDesk data. This article shows how to connect to Connect AI and use pandas and Dash to build a simple web app for visualizing ZohoDesk data.

The Connect AI Python SDK (cdata-connect-ai) is a DB-API 2.0 (PEP 249) compliant client, so pandas can read query results directly from the SDK connection object. There is no driver to install per source: connect with a Personal Access Token and build your app.

Connect to ZohoDesk in Connect AI

CData Connect AI uses a straightforward, point-and-click interface to connect to data sources.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "ZohoDesk" from the Add Connection panel

3. Enter the necessary authentication properties to connect to ZohoDesk.

   To connect to Zoho Desk, register a Server-based Application in the Zoho Developer Console (accounts.zoho.com/developerconsole). Set the Authorized Redirect URI to https://oauth.cdata.com/oauth/. Note the Client Id and Client Secret. Then set the following:

   • OAuth Client Id: The Client Id from your Zoho Developer Console application.
   • OAuth Client Secret: The Client Secret from your Zoho Developer Console application.
   • Organization: (Optional) The Id of your Zoho Desk organization, found in the Organizations table.
   • Domain: (Optional) Your Zoho region domain — .com (default), .eu, .com.au, or .in.

   Click Sign In to complete OAuth authentication.

   
4. Click Save & Test
5. Navigate to the Permissions tab and update the user-based permissions.

Generate a Personal Access Token (PAT)

The Python SDK authenticates to Connect AI with your account email and a Personal Access Token (PAT). It is best practice to create a separate PAT for each application to maintain granularity of access.

1. Click the Gear icon () at the top right of the Connect AI app to open the Settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The PAT is only visible at creation, so copy it and store it securely.

Install Required Modules

Install the SDK (with the pandas extra), Dash, and Plotly using the pip utility:

pip install "cdata-connect-ai[full]"
pip install dash
pip install plotly

Build a Web App on ZohoDesk Data in Python

Once the required modules are installed, you are ready to build the web app. Code snippets follow, but the full source code is available at the end of the article.

First, import the modules, then connect to Connect AI with your account email and PAT and read ZohoDesk data into a DataFrame. Identifiers are three-part: <Connection>.<Schema>.<Table>, where the connection name defaults to the source name (for example, API1).

import dash
from dash import dcc, html
import pandas as pd
import plotly.graph_objs as go
import cdata_connect_ai

conn = cdata_connect_ai.connect(
    username="[email protected]",
    password="<your_pat>",
)

df = pd.read_sql(
    "SELECT Id, CompanyName "
    "FROM [API1].[API].[AccessibleOrganizations] "
    "WHERE IsDefault = 'true'",
    conn,
)

conn.close()

Configure the App and Layout

With the query results stored in a DataFrame, build a bar graph from the ZohoDesk data and configure the app layout.

app = dash.Dash(__name__)
app.title = 'CData Connect AI + Dash'

trace = go.Bar(x=df['Id'], y=df['CompanyName'], name='Id')

app.layout = html.Div(
    children=[
        html.H1("CData Connect AI + Dash", style={'textAlign': 'center'}),
        dcc.Graph(
            id='example-graph',
            figure={
                'data': [trace],
                'layout': go.Layout(title='ZohoDesk AccessibleOrganizations Data', barmode='stack'),
            },
        ),
    ],
    className="container",
)

Set the App to Run

With the connection, app, and layout configured, you are ready to run the app.

if __name__ == '__main__':
    app.run(debug=True)

Now, use Python to run the web app and a browser to view the ZohoDesk data.

python api-dash.py
