Workato SDK Reference

Comprehensive reference for all Workato Connector SDK blocks, methods, and configuration options.

Overview

The Workato SDK consists of these main blocks:

Connection Block

Defines authentication and connection settings.

connection: {
  fields: Array,           # Credential input fields
  authorization: Hash,     # Auth type and configuration
  base_uri: lambda,        # Base URL for requests
  test: lambda            # Connection test
}

Authorization Types

Actions Block

Defines connector operations.

actions: {
  action_name: {
    title: String,                    # Display name
    subtitle: String,                 # Secondary description
    description: lambda,              # Dynamic description
    help: String | lambda,            # Help text
    config_fields: Array,             # Mode selectors
    input_fields: lambda,             # Input schema
    execute: lambda,                  # Main logic
    output_fields: lambda,            # Output schema
    sample_output: lambda,            # Sample data
    retry_on_response: Array,         # HTTP codes to retry
    retry_on_request: Array,          # Errors to retry
    max_retries: Integer,             # Retry count
    summarize_input: Array,           # Input summary fields
    summarize_output: Array           # Output summary fields
  }
}

Execute Lambda Parameters

execute: lambda do |connection, input, extended_input_schema, extended_output_schema, continue|
  # connection - credentials hash
  # input - user inputs
  # extended_input_schema - dynamic schema info
  # extended_output_schema - dynamic output schema
  # continue - multistep continuation data
end

Triggers Block

Defines event triggers.

triggers: {
  trigger_name: {
    title: String,
    description: lambda,
    config_fields: Array,
    input_fields: lambda,
    poll: lambda,                     # Polling logic
    webhook_subscribe: lambda,        # Webhook registration
    webhook_unsubscribe: lambda,      # Webhook cleanup
    webhook_notification: lambda,     # Webhook handler
    dedup: lambda,                    # Deduplication
    output_fields: lambda,
    sample_output: lambda
  }
}

Poll Lambda Returns

poll: lambda do |connection, input, closure|
  {
    events: Array,          # Records to process
    next_poll: Any,         # Stored in closure
    can_poll_more: Boolean  # Continue polling?
  }
end

Methods Block

Reusable helper functions.

methods: {
  method_name: lambda do |arg1, arg2|
    # Logic here
  end
}

Calling Methods

result = call('method_name', arg1, arg2)

Object Definitions Block

Reusable field schemas.

object_definitions: {
  schema_name: {
    fields: lambda do |connection, config_fields, object_definitions|
      [
        { name: 'field_name', label: 'Label', type: 'string' }
      ]
    end
  }
}

Referencing Object Definitions

input_fields: lambda do |object_definitions|
  object_definitions['schema_name']
end

Pick Lists Block

Dropdown options.

pick_lists: {
  # Static list
  statuses: lambda do
    [
      ['Active', 'active'],
      ['Inactive', 'inactive']
    ]
  end,

  # Dynamic list
  objects: lambda do |connection|
    get('/api/objects').map { |o| [o['name'], o['id']] }
  end,

  # Dependent list
  fields: lambda do |connection, object_type:|
    get("/api/objects/#{object_type}/fields").map { |f| [f['label'], f['name']] }
  end
}

HTTP Methods

Request Methods

Request Modifiers

get('/api/records')
  .params(key: 'value')              # Query parameters
  .payload(data)                     # Request body
  .headers('X-Custom' => 'value')    # Custom headers
  .request_format_json               # JSON body (default)
  .request_format_xml                # XML body
  .request_format_www_form_urlencoded # Form body
  .request_format_multipart_form     # Multipart body
  .response_format_json              # Parse JSON (default)
  .response_format_xml               # Parse XML
  .response_format_raw               # Raw response

Error Handling

get('/api/records')
  .after_response do |code, body, headers|
    # Handle any response
  end
  .after_error_response(400) do |code, body, headers, message|
    # Handle specific error
  end
  .after_error_response(/4\d{2}/) do |code, body, headers, message|
    # Handle error pattern
