Host object that the script is eval’d against. Exposes the helper API. Defined as a class (not a Module) so ‘instance_eval` gives the script access to standard top-level Ruby plus our helpers, without polluting Object globally.

def call_method(name, *args)
  proxy = sdk_connector.methods
  unless proxy.respond_to?(name.to_sym)
    raise InvalidReturn, "No methods entry named '#{name}' found in connector."
  end
  proxy.public_send(name.to_sym, *args)
end

#call_pick_list(name, **args) ⇒ Object

Invoke a connector ‘pick_lists:` entry. `args` is a Hash of named arguments for dependent pick lists. The SDK supplies `connection` to the lambda automatically.

Examples:

call_pick_list(:active_customers)
call_pick_list(:customer_orders, customer_id: 123)

def call_pick_list(name, **args)
  proxy = sdk_connector.pick_lists
  unless proxy.respond_to?(name.to_sym)
    raise InvalidReturn, "No pick_lists entry named '#{name}' found in connector."
  end
  # SDK signature: pick_list_name(settings = nil, args = {})
  # Passing nil for settings tells the SDK to reuse the connector's settings.
  proxy.public_send(name.to_sym, nil, args)
end

#connection ⇒ Object

Hash of decrypted settings for the configured connection. Returns {} and emits a one-time warning if settings can’t be loaded.
