Title: Creating custom connections for extensions | Community | Zoho Finance

In our previous post, we discussed the significance of connections, identified their types, developed a predefined connection, and demonstrated how it can be integrated with Zoho Books using an example. In this post, we'll walk through the process of creating a custom connection using an example.

Custom connections facilitate the integration of applications with Zoho Books by aiding in configuring the required application's connection manually by providing application-specific details. Let's go over the steps involved in configuring custom connections in detail using a use case scenario.

Use case

Let's say an organization uses Zoho Books to manage its financial operations. To improve sales for the organization, one must contact and communicate with multiple clients, as well as check in with vendors on a regular basis to remain up to date on new products on the market, take demos, and assess whether the products need to be brought into the organization.

In these cases, it is best to schedule appointments with clients and vendors in order to conduct business in an organized manner. This can be easily performed by integrating an appointment scheduling software so appointments can be scheduled with a click.

For our demo purpose, let's consider Zoho Bookings as the appointment scheduling software. Since it is not available under the default list of services in predefined connections, let's create a custom connection to achieve this.

Steps to create a custom connection
  • Go to Sigma and access your workspace.
  • Enter the developer portal of the Zoho Books extension you're creating a connection for.
  • Navigate to the Build section and click Connections.
   
  • Click New Connection to create a new connection.
NotesNote: Alternatively, you can use the View All option under a connection type to see all the services under that particular connection type and begin creating connections.
     
  • Choose Custom Services and click Create Service.
   
  • Provide the details of the service.
➤ Enter a name for the service, and the service link name will be immediately filled in.
➤ Choose the authentication type that corresponds to the authentication mechanism supported by the service for which you are building the connection. These details will be available as part of the service's API documentation. For our example, we'll use OAuth2, because Zoho Bookings supports it as an authentication mechanism.         
  
➤ The remaining fields to be configured for the service differ based on the authentication type used. In our case, the parameter type is Header, and the grant type is Authorization Code.
   
➤ Please refer to the table below for the values that need to be configured in the remaining fields.
Note: Register the service in the Zoho Developer API console to get the client credentials.
  • Finally, click the Create Service button.
  
  • The service is created successfully. Click Create Connection to create a connection for this service.
  • Provide the connection details, select the scope, and click Create and Connect.
 
  • Proceed with the flow to accept the scopes and authorize the connection.
 

The connection is now authorized, and you'll be directed to the connection details page. This page will also contain sample code in both Deluge and JSON formats that can be used to utilize this connection as part of your extension components. Depending on which component you want to invoke the connection in, you can use the appropriate sample code format.

Additionally, a predefined connection for Zoho Books is created to perform operations on Zoho Books data to implement our use case. Get more information on predefined connections in our previous post.

Now, in accordance with our use case, let's create a custom button that includes this connection to schedule appointments (in Zoho Bookings) with clients and vendors using Zoho Bookings with a single click (from Zoho Books).
We require two custom fields for our logic, one for setting the meeting start time with the client or vendor, and the other to display the Bookings appointment calendar link once the meeting is scheduled.
  • Create custom fields for the Customers and Vendors module by selecting Preferences > Customers and Vendors > Field Customization > New Custom Field.
 
  • Next, create a custom button and include the logic to schedule an appointment.
  • Create a custom button for the Customers and Vendors module by selecting Preferences > Customers and Vendors > Custom Buttons > New.
InfoBook meeting custom button function Deluge code - Please find code snippet as an attachment in the post
  • In the above code, the Get Contacts API of Zoho Books is invoked through the InvokeURL method using the predefined connection to get the contact/customer details for whom the appointment has to be scheduled in Zoho Bookings. Refer to this post to get complete details on the parameters required to call the InvokeURL method.
  • From the API response, the required details are fetched from which the start time (custom field data) is formatted to the way required by the Zoho Bookings API.
  • Next, the Zoho Bookings API to get the service ID and staff ID are invoked consecutively through the InvokeURL method using the custom connection created.
  • The Book appointment API is used to schedule the appointment using the service ID, the staff ID obtained from the Zoho Bookings API, and customer details obtained previously via the Zoho Books API.
  • Finally, using the update contact Zoho Books API, the Zoho Bookings calendar URL is updated in the custom field created to display the calendar booking URL.
We've now completed the extension setup for our use case.

After testing and publishing the extension, as per our use case, you can book a meeting for a Zoho Books customer through Zoho Bookings and have your Zoho Bookings calendar reflected inside Zoho Books as well.

z
This is an example demonstration of the benefits of using a custom connection in a Zoho Books extension. This is a versatile use case that may even be used to schedule an internal meeting with your Zoho Books teammates who are working on a project. Similarly, this use case can be enhanced and implemented based on your needs.

We hope you found this information useful. Keep following us for more tips.
