1. Default connections: Zoho provides a default set of applications that you can simply select, provide some basic information for, and connect to.
   
2. Custom connections: If the application you want to integrate with Zoho Sprints is not on the default list, or you want to make some customizations to your connection, you can create a custom service and then connect to it.

1. Go to Sigma and navigate to the Connections section in the left panel of your Sigma workspace.

1. Choose Zoho Sprints as the service from the dropdown list, then select your Zoho Sprints organization.
   

1. Click Create Connection to start creating a connection for the application you want to integrate with Zoho Sprints.
   

Note: Alternatively, you can also use the Default Services or Custom Services option under the Services section to access and create a default or a custom connection respectively.

1. Refer to the "How to create a connection" section for the first three steps to create a connection.
   

1. Select the Default Services tab.
   

1. Check for Zoho Projects in the service list by simply searching for it.
   

1. Once located, click on the service. You will be redirected to the page where you must enter your connection details.
   

➤ Enter the connection name. The connection link name will be automatically filled in.

➤ Toggle Yes to Use Credentials of Login User if you want every user who installs the extension to authorize the connection using their credentials. Otherwise, toggle No to have only the admin authorize the connection once.

➤ Select the scopes for the APIs required to enable your extension's functionality.

➤ Click Create and Connect.

1. The connection will be established successfully, and sample JSON code will be generated, which must be specified in the extension's plugin-manifest.json file before it can be used to invoke Zoho Projects APIs within the extension.

Note: If you want to use the Zoho Sprints APIs within the extension, you can establish a default connection for Sprints, configure it in the plugin-manifest.json file, and use it to access the Zoho Sprints APIs.

1. Create connections
   
2. Create an extension and configure the plugin-manifest file
   
3. Create a widget to start an Assist session from within a work item and add a comment to it.

1. Select Custom Services.
   
2. Click the Create New Service option.
   

1. You'll be redirected to a page where you need to enter your connection details.
   

➤ Enter the Service name. The service link name will be automatically filled in.

Choose the authentication type of the service you are creating the connection for. The parameter type and grant type options get populated depending on the authentication type chosen. The screenshot below displays the values chosen for the Zoho Assist service example based on its authentication mechanism.

➤ Next, provide the client credentials (obtained by creating an app in the Zoho API console).

➤ Enter the scopes of the Zoho Assist APIs required for your extension's functionality.

➤ Click Create Service.

1. The service will be successfully created, and you'll be taken to a page where you can now go ahead and create a connection. In this page, you'll have to enter the details just like you provided connection details for your default connection.
   

Note: You can read this document for detailed guidance on creating a custom service and providing the necessary details.

1. Enter a connection name, toggle Yes or No to Use Credentials of Login User, select the scopes, and click Create and Connect.
   

1. You'll be asked to authorize the connection and provide access to your data for the scopes included. Accept and proceed.
2. The connection will be successfully created and a sample JSON will be automatically generated.
   

1. Since our example involves adding a comment to the Sprints work item as well, we'll be invoking the Sprints API for it. To access its API, a connection for Zoho Sprints is also required. This can be created as a default connection using the method shared in the earlier section.
   

1. Navigate to the Extensions section in the left panel of your Sigma workspace.
   
2. Click the New Extension button and create a new extension. You can refer to this post for detailed guidance on creating a new extension.
   
3. In the plugin-manifest.json file of your extension, include the sample JSON code that was generated for the Zoho Assist connection you created. Also include the JSON code for the Sprints connection you created.
   

1. Create a file called createsession.html inside the app folder to render and handle the logic of your widget.
   
2. This widget has to be configured in the plugin-manifest.json file with the following details.
   

➤ name: The name of the widget: "Zoho Assist Session"

➤ location: The location in which the widget needs to be rendered. This widget's location is in the work item's right navigation bar.

➤ url: The URL path of the createsession.html file in the folder structure which renders the widget's user interface.

Note: Read our documentation to learn more about widgets.

➤ In the attached code snippet, we have invoked the Zoho Sprints API to fetch the list of Sprints workspace users. This user list is populated as a dropdown list to let the person accessing the widget choose the user they want to enter into an Assist session with. This API is invoked using a default connection created for Zoho Sprints.

➤ Next, the Zoho Assist API is used to start and create a session with the chosen user. The custom connection created for Zoho Assist is used to invoke this API.

➤ Finally, another Sprints API is invoked to add a comment that includes the session details to the work item.

1. Now, you can test the widget using the Run option in the Sigma cloud editor. For detailed guidance on testing the extension, read our post here.
   
2. Once you enter into the test environment, install the extension and authorize the connections.
   

1. Next, enter into the work item and access the Zoho Assist Session widget. Choose the user and session type, and click Start Session. The session will be successfully initiated and a comment regarding the session details will also be added to the work item.
