Switch

Overview

The switch expression is a control flow expression that evaluates a list of boolean conditions in order. The first true condition executes its steps; if none match, it runs the optional default. Each case pairs a condition with a list of expressions; empty steps allow silent passes.

Low-Code Editor

Add a switch step, define DSL conditions per case and add expressions inside each case.

Define the Number of Cases: Click on the ”+” or ”-” symbol to add or remove cases.
Define Condition in a Case: Select a case block; enter a boolean DSL expression in the editor (e.g., data.operation == "sum")’
Add Steps in the Case: Click ”+” inside the case to add expressions.
Configure the Default: Add fallback steps. Omit for silent skips on no-match.

Schema

1 switch:
2   cases:                          # list: Sequence of condition-step pairs (required)
3     - condition: DSL_BOOLEAN_EXPR  # boolean: DSL expr (e.g., "data.user_id == meta_info.user.id")
4       steps:                      # list: Nested expressions (e.g., actions)
5         - EXPRESSION_1
6         - EXPRESSION_2
7     - condition: ANOTHER_EXPR
8       steps:
9         - EXPRESSION_3
10   default:                        # dict: Fallback if no cases match (optional)
11     steps:                        # list: Default expressions
12       - EXPRESSION_4

Fields

Field	Type	Mandatory	Description
`cases`	list[dict]	Yes	Sequential checks: First true runs its steps
`condition`	boolean	Per case	DSL expressions
`steps`	list[expr]	No	List of expressions to execute. Can be empty `[]`
`default.steps`	list[expr]	No	Catch-all list of expressions.

Practical Examples

Example 1: Simple ID Match

Notify only if the user is not the requestor

1 switch:
2   cases:
3     - condition: meta_info.user.id == data.requestor.record_id
4       steps: []  # Skip if self-add
5   default:
6     steps:
7       - action:
8           action_name: mw.send_plaintext_chat_notification
9           output_key: notification_sent
10           input_args:
11             user_record_id: data.user.record_id
12             message: 
13             	RENDER():
14               template:"Hey {{user_name}}, {{requestor_name}} added you to a special group"
15               args:
16               	user_name: meta_info.user.full_name
17 								requestor_name: data.requestor.full_name

Expectation: If there’s a match, stay silent; If not, send a message to the user

Example 2: Role-Based Welcomes

Tailor onboarding by access level.

1 switch:
2   cases:
3     - condition: data.user.access_level == "admin"
4       steps:
5         - action:
6             action_name: send_admin_welcome
7             output_key: admin_msg
8             input_args:
9               user_id: data.user.id
10               message: '''Welcome, Admin! Full dashboard access unlocked.'''
11     - condition: data.user.access_level == "member"
12       steps:
13         - action:
14             action_name: send_member_welcome
15             output_key: member_msg
16             input_args:
17               user_id: data.user.id
18               message: '''Welcome, Member! Dive into your profile perks.'''
19   default:
20     steps:
21       - action:
22           action_name: send_generic_access_notification
23           output_key: generic_msg
24           input_args:
25             user_id: data.user.id
26             message: '''Account ready—start exploring!'''

Expectation: Routes to specific action and welcome message based on user’s access level.

Example 3: Temperature Thresholds

Alert or log based on sensor data

1 switch:
2   cases:
3     - condition: data.temperature <= 5
4       steps:
5         - action:
6             action_name: alert_cold_temperature
7             output_key: cold_alert
8             input_args:
9               message: '''Alert: Very cold—check heating!'''
10     - condition: data.temperature > 5 AND data.temperature <= 25
11       steps:
12         - action:
13             action_name: log_moderate_temperature
14             output_key: mod_log
15             input_args:
16               message: '''Moderate temp: All good.'''
17   default:  # >25 implied
18     steps:
19       - action:
20           action_name: alert_high_temperature
21           output_key: high_alert
22           input_args:
23               message: '''Alert: High temp—activate cooling!'''

Expectation: Based on the temperature send an alert or log.
