Custom Plugins

Build custom plugins to create reusable integrations. Package your APIs for easy use across workflows.

What is a Custom Plugin?

A plugin packages:

• API connection details
• Available actions
• Authentication method
• Input/output schemas

Once created, use like built-in plugins.

Creating a Plugin

Start New Plugin

1. Go to Plugins > Create Plugin
2. Enter plugin details:
   • Name
   • Description
   • Icon
   • Category

Configure Connection

Set up the base configuration:

baseUrl: https://api.example.com/v1
authentication:
  type: api_key
  header: X-API-Key

Add Actions

Define what the plugin can do:

Example: Create User

actions:
  - name: create_user
    displayName: Create User
    description: Creates a new user
    method: POST
    path: /users
    inputs:
      - name: email
        type: string
        required: true
      - name: name
        type: string
        required: true
    output:
      type: object
      properties:
        id: string
        email: string

Add Triggers (Optional)

For webhook-based triggers:

triggers:
  - name: user_created
    displayName: User Created
    description: Fires when a new user is created
    webhookPath: /webhooks/user-created

Plugin Structure

Manifest

The plugin.yaml defines everything:

name: my-service
displayName: My Service
description: Connect to My Service API
version: 1.0.0
icon: custom-icon.svg
category: productivity

connection:
  baseUrl: https://api.myservice.com
  authentication:
    type: oauth2
    authorizationUrl: https://myservice.com/oauth/authorize
    tokenUrl: https://myservice.com/oauth/token
    scopes:
      - read
      - write

actions:
  - name: get_item
    # ... action definition

triggers:
  - name: item_created
    # ... trigger definition

Actions

Each action needs:

| Field | Description | |-------|-------------| | name | Internal identifier | | displayName | Shown in UI | | description | Help text | | method | HTTP method | | path | Endpoint path | | inputs | Parameters | | output | Response schema |

Input Types

Supported input types:

• string - Text input
• number - Numeric
• boolean - True/false
• array - List of items
• object - Nested object
• select - Dropdown options

Testing Plugins

Test Panel

1. Open your plugin
2. Click Test
3. Select an action
4. Enter test data
5. View response

In Workflows

Test in a real workflow:

1. Create test workflow
2. Add your plugin action
3. Run with test data
4. Verify behavior

Publishing

Private (Default)

Only visible in your workspace.

Team

Share with organization:

1. Go to plugin settings
2. Enable Share with team
3. Team can now use it

Public (Marketplace)

Share with everyone:

1. Ensure quality standards
2. Click Publish to Marketplace
3. Complete submission form
4. Wait for review

See Publishing Plugins.

Advanced Features

Dynamic Inputs

Inputs that depend on other values:

inputs:
  - name: workspace
    type: select
    dynamicOptions:
      action: list_workspaces
  - name: channel
    type: select
    dependsOn: workspace
    dynamicOptions:
      action: list_channels
      params:
        workspace: "{{workspace}}"

Pagination

Handle paginated APIs:

pagination:
  type: cursor
  cursorParam: next_cursor
  cursorPath: response.next_cursor

Rate Limiting

Respect API limits:

rateLimit:
  requests: 100
  period: 60 # seconds

Best Practices

1. Clear naming - Descriptive action names
2. Good descriptions - Help users understand
3. Handle errors - Define error responses
4. Test thoroughly - All actions and edge cases
5. Version properly - Semantic versioning
