A

Account

Identity

Your personal user profile, identified by your email address. It travels with you across workspaces, while your workspace role controls what actions you can perform.

Learn more in Account & Authentication →

Action

Canvas Steps

A Step that performs an external or built-in operation. Examples include sending an email, updating a CRM record, or running code.

Learn more in Triggers and Actions →

App drawer

Canvas UI

The right-hand configuration panel for a selected Step. It provides Setup, Executions, and Test & Debug tabs, where tests can perform real actions in connected services.

Learn more in The Dock & App drawer →

Automation

Core Architecture

A set of connected Steps built on the canvas. It combines triggers, actions, data transformations, and flow controls in sequence.

Learn more in What Is an Automation? →

B

Billing and usage

Workspace Settings

The workspace billing page at /app/subscription. It shows usage meters, published unit prices, invoices, payment methods, and billing safeguards based on your billing permissions.

Learn more in Billing & Usage Overview →

C

Canvas

Core Interface

The multiplayer visual workspace for building and operating automations. It renders triggers, action Steps, routing branches, sticky notes, and live collaborator cursors.

Learn more in Steps and Connections →

Client workspace

MSP & Governance

A client organization’s workspace managed under a delegation grant. The grant controls operational access without creating a billing agreement.

Learn more in How Multi-Tenancy Works →

Conditions

Flow Control

A flow control Step that evaluates structured rules. Every matching branch runs, while an optional Else branch runs when no rules match.

Learn more in Conditions Step →

Connection (app)

Integrations

A connected app account authenticated via OAuth or API credentials. Steps use the selected connection within that account’s permissions.

Learn more in Connecting an App →

D

Date

Data Tools

A data Step that formats, compares, and shifts timestamps. It can also extract calendar parts such as month or weekday.

Learn more in Date Step →

E

Execution

Engine & Runtime

One run of an automation started by a trigger or test. An execution ID links its Step attempts, inputs, and outputs.

Learn more in Step-Level Executions →

F

Flow

Flow Control

The dock group of built-in logic Steps. It includes Conditions, Switch, Filter, Repeater, Wait, Human Review, Stop and Error, and Do Nothing.

Learn more in Choosing a Flow Step →

G

Glow AI Tokens

AI & Billing

The consumption unit for hosted AI features in Glow. Billable usage equals input, output, and reasoning tokens, resets monthly, and never converts into Step credits.

Learn more in Step Credits, Tokens & Storage →

Grant

MSP Governance

A delegation agreement from a client Admin to a partner. Grants specify the access tier (Read-only or Full operational), covered automations, expiration, and audit logging.

Learn more in Governance & Impersonation →

H

HTTP Mode

Step Configuration

Manual field configuration for an eligible app action in the App drawer. Select it from the HTTP | MCP toggle in the Step’s ⋮ menu; it is distinct from the HTTP Request Step.

HTTP Request

Developer Tools

A built-in Step under Tools → Data → Dev tools for custom HTTP calls. It supports GET, POST, PUT, DELETE, and PATCH within authentication, timeout, and payload limits.

Learn more in HTTP Request →

I

Interface

Templates & Forms

The canvas drawer that turns an automation into a standalone form. Users submit inputs without opening or modifying the canvas.

Learn more in Form Templates →

L

Loop

Batch & Iteration

Repeated execution over a list. Run for each item repeats a single action Step over a list, while Repeater repeats a multi-Step loop body.

Learn more in Loops & Iteration →

M

MCP Mode

Step Configuration

Natural-language configuration for an eligible app action in the App drawer. Select it with the HTTP | MCP toggle in the Step’s ⋮ menu, or switch to HTTP for manual fields.

Model Context Protocol (MCP)

Developer & AI

An open standard connecting AI clients to external tools. Glow provides an MCP server for AI editors and an MCP client for AI Agents.

Learn more in Model Context Protocol (MCP) →

P

Prepaid Resource Model

Billing Architecture

A billing model using purchased Step credits, Glow AI tokens, and retained storage. Exhausting a balance pauses new work requiring that resource without reversing completed external actions.

Learn more in Billing & Usage Overview →

R

Record

Data Structures

A structured key-value data object such as a contact or invoice. Steps pass, map, and transform collections of records across an automation.

ret

Variable Syntax
The response key used by Glow’s HTTP Request Step (for example, {{ 3.ret.id }}). App actions expose their return value directly without a ret wrapper.
Learn more in Variable Reference Syntax →

Retained Storage

Storage & Billing

Persistent workspace cloud storage (in GB) for files and documents. Retained storage is standing capacity and never resets monthly.

Learn more in Step Credits, Tokens & Storage →

Role

Team & Security

A workspace user’s permission tier: Admin, Manager, Member, or Viewer. Admins, Managers, and Members build and run accessible automations, while Viewers see permitted diagrams and run summaries, not configuration or execution payloads.

Learn more in Permissions and Access →

S

Scheduler

Triggers

A built-in trigger that starts runs on a recurring schedule. Configure it using plain-language intervals or cron expressions.

Learn more in Scheduler Trigger →

Secret

Security & Config
An encrypted workspace credential such as an API key or password. Reference it at runtime with {{ $secret.KEY }} instead of pasting raw credentials into Step fields.
Learn more in Secrets and Variables →

Starting Point

Canvas Testing

The trigger or Step selected in the dock when starting a manual test run.

Step

Core Concept

The fundamental building block on the Glow canvas. Every trigger, action, AI model, and flow control is a Step with a permanent Step number.

Learn more in Steps and Connections →

Step Credit

Billing & Execution

A unit used to meter automation actions. Consumption depends on the action’s published rate and work performed, and some actions cost no Step credits.

Learn more in Step Credits, Tokens & Storage →

Subflow

Modular Automations

A canvas Step that runs another automation as a child routine. It waits for the child run’s result before continuing.

Learn more in Calling Another Automation (Subflow) →

Summarize

Data Tools
A data Step that aggregates lists into grouped summaries under {{ N.groups }}. Supported operations include count, sum, average, min, max, list, and join.
Learn more in Summarize Step →

Switch

Flow Control

A routing Step that checks ordered cases against an input value. It runs only the first matching branch or the fallback.

Learn more in Switch Step →

T

Team / Workspace

Collaboration

The shared organizational unit for automations, connections, variables, files, and billing. Member roles and visibility settings govern access inside a workspace.

Learn more in Setting Up Your Team →

Template

Marketplace

A reusable automation blueprint from the Marketplace or your team library. Fork it into a workspace canvas to customize and run it.

Learn more in Templates and Reuse →

Trigger

Canvas Entry

The entry Step that starts an automation run. Examples include Webhook, Scheduler, Chat Trigger, Form Trigger, and app events.

Learn more in Triggers and Actions →

V

Variable

Data & State
A dynamic value used in Step fields. {{ N.field }} reads a Step output for the run, while {{ $var.KEY }} reads a persistent workspace variable.
Learn more in Secrets and Variables →

W

Wait

Flow Control

A flow control Step that pauses execution for up to 13 days. The run resumes automatically when the timer elapses.

Learn more in Wait (Delay) Step →

Webhook

Triggers & REST

A trigger Step that exposes an HTTPS endpoint for incoming requests. It supports optional HMAC signature verification and synchronous responses.

Learn more in Webhook Trigger →

Workflow

Core Architecture

A synonym for an automation built and run on the canvas.

Learn more in What Is an Automation? →

Workflow data panel

Canvas Data Picker

The data picker opened from a field’s data icon. It inserts references using retained outputs, saved test data, or predicted fields. Check the actual output before relying on a suggested field.

Learn more in Workflow Data →

Workspace

Administration

The team environment you are currently operating in. Access depends on your role, automation visibility, and any active delegation grant.
