Private Plugins

This feature requires an Enterprise license. Please contact [e-mail] to enable the developer console on your account.

Private plugins, unlike their public counterpart, are developed, maintained and deployed by Ubidots users in order to meet requirements that are not natively addressed by the platform.

A private plugin is structured around a specific set of files. These files not only determine the plugin type but also define its logic and overall functionality. The typical file structure for a plugin, regardless of its type, is outlined below:

├── src
│   ├── some_files_or_folders    
├── LICENSE
├── README.md
├── manifest.toml 

Adhering to this file structure and including all the mentioned files is mandatory for the plugin to be deployed and function correctly.

src directory

the src directory holds the primary components of the plugin. This is where the core logic, main functionalities, and some configuration files are defined.

For more specific details about the contents of this directory, please refer to the dedicated section for each type of plugin:

CronWebhookWidgetDevice

manifest.toml

In a broad sense, the manifest file defines the plugin's identity and behavior, that is, it outlines:

• Its type

• Plugin's current version

• Plugin's price

• Environmental variables

This file contains both shared components that apply to all plugin types and unique components that are specific to each plugin type.

The typical manifest file common to all plugins is composed by:

Section	Key	Value	Description	Example
[-]	manifest_version	A valid manifest version. Currently 2.0 is the only one supported.	Manifest version.	manifest_version = 2.0
[settings]	version	Any number, according to your versioning system.	Plugin's current version.	version = "1.1.1"
[settings]	plugin_type	cron, webhook, device, widget.	Type of plugin	plugin_type = "widget"
[settings]	license_name	A valid license name.	The name for your plugin's license.	license_name = "MIT license"
[pricing]	price*	A float number.	This is the price that the developer wants to set for the plugin.	price = 10
[environment]	Any variable name*	Any value for the variable.	Allows to set environment variables within the plugin.	UBIDOTS_URL = "https://industrial.api.ubidots.com"

With that in mind, a manifest file that is common to all plugins, regardless of their type, looks like this:

manifest_version = 2.0

[settings]
version = "1.1.1"
plugin_type = "cron" | "webhook" | "device" | "widget"
license_name = "MIT license"

[pricing]
price = 10

[environment]
UBIDOTS_URL = "https://industrial.api.ubidots.com"

For detailed information about the specific manifest file components particular to each plugin type, refer to their dedicated pages.

Manifest's file keys marked with a * are not mandatory.
