Connections in Zoho IoT provide a secure and standardized way to integrate the Zoho IoT application with other applications, including other Zoho services and third-party platforms. They establish authenticated access, allowing the application to securely and reliably utilize the data and functionalities offered by these services.
By using Connections, organizations can streamline integrations, maintain centralized credential management, and enable data transfer without repeated setup or additional coding.
Once the connection is created and connected, as shown in the image below, the same connection reference can be used in multiple places within the Zoho IoT application to access Zoho IoT APIs or other service APIs.

Creating Connections
Now let’s look at the step-by-step procedure to create connections in the Zoho IoT application to integrate with other Zoho services and third-party services.
Access the Developer Application.
- Select the Automate tab, and select Connections in the left pane. The available connections will be displayed.
Note: Connections created by the user and the administrator of the organization are listed here. You can let other users of the organization utilize your connections. Changes made to such connections will also affect the users who utilize them.
- Click Create Connection button in the top right corner of the screen.

Select the required service from the available default services list. Services act as connectors that allow you to create connections. The available types of services are: Default and Custom Services.
Default Services - These are pre-configured services available in Zoho IoT. You can easily create a connection for any of the default services listed and authenticate it using your credentials.
- Custom Services - If the service you need is not listed by default, you can manually configure it. Once configured, you or other members of your organization can create multiple connections to that service as needed, simply by providing the required credentials.

Enter the connection name. The connection link name will be generated and displayed.
- Set the Use Credentials of Login User toggle to ON to use your credentials automatically when establishing the connection.

Select from the scopes available for the selected service. Scope defines the specific set of permissions or access rights that the connection grants to an external service or application.
For example, when you create a Connection to Zoho Creator in Zoho IoT, you’ll need to define the scope. This scope determines what level of access Zoho IoT will have inside Zoho Creator.
ZohoCreator.dashboard.READ
→ Allows Zoho IoT to read dashboard data in Creator.
ZohoCreator.data.CREATE
→ Allows Zoho IoT to insert new records into a Creator app (e.g., log IoT device data).
ZohoCreator.data.UPDATE
→ Allows Zoho IoT to update existing records in Creator.
ZohoCreator.form.CREATE
→ Allows Zoho IoT to create form records in Creator.
8. Click Create and Connect to create and proceed to establish connection.
Note: This screen will vary based on the selected service.
9. Click Connect to establish connection. The following access permissions screen is displayed.
Note: This connect screen will vary based on the selected service.
10. Click Accept. The resultant screen with connection details is displayed.
11. Click Connect next to the connection name on the top of the screen. The connection is established and the button will change to REVOKE, and the status will change to Connected.
12. The
Deluge and JSon sample code will be displayed in the respective tabs below the Connection Summary.

13. The new connection can be used in
Webhooks by just associating the connection name, and in
Custom Function by providing the connection name against connection property.

Using Connections in Webhook & Custom Function
After creating a connection in the Zoho IoT application and activating it, you can use it in any Webhook action or Custom Function.
In Webhook:You need to select the Authentication Type as Connections and choose the Connection to associate.
Refer to the Creating Webhooks document to know how connections are used in webhooks.
In Custom Functions:
You can copy paste the deluge script in the Custom Function. Refer to the
Custom Functions document for more details.
Editing Connections
Any connection can be edited as required using the options available in the Connections page.
For additional details, refer to the deluge Connections document.
Deleting Connections
Connections that are not associated to any webhook can be deleted from the application.
To delete a Connection:
Click on the ellipsis next to the connection name and connect/revoke button.
Click Delete.
or
Click the Delete icon on the Connection in the connection's home page.

Click Delete in the confirmation box. The connection will be deleted if there are no associations.
If there are associations to the connection from webhook, the dependency message popup will be displayed, and the connection will not be deleted.
