Workflow Modules Reference¶

Workflow modules are the building blocks of workflows — triggers, actions, and utilities that users drag onto the canvas. Stored in the workflows_modules table (regional DB).

For table schema, see Database Tables Reference.

App Types¶

The app_type field groups modules by their parent app/platform. It's used for: - Icon resolution in the UI (via apps_branding table and frontend appIconUrls constant) - Partner branding replacement (Stacksync modules get partner icon/name) - Resource table "Apps" column (extracted from module_id via split_part(module_id, '-', 1))

Stacksync Platform App Types¶

These are built by Stacksync. For partner workspaces, their icons and "Stacksync" in names get replaced with the partner's branding.

`app_type`	Display Name	Notes
`stacksync_ai`	Stacksync AI	AI Prompt, Search, Crawl Website, Scrape Page, Extract Data, Map Website
`stacksync_ocr`	Stacksync OCR	Process Documents
`stacksync_email`	Stacksync Email	Send Email, Reply Email, Forward Email
`stacksync-enrichment`	Stacksync Enrichment	LinkedIn enrichment modules (Get Posts, Enrich Records, List Records, Search Live)
`file_service`	File Service	Get File Content
`system`	Standard modules	Platform utilities: If Else, For Loop, While Loop, Transform Data, Wait, Stop Workflow, Merge JSON, Data Aggregator, Webhook Trigger, Cron Schedule Trigger, Email Trigger, HTTP Request, Encode/Decode, Cast, Try Catch, Workflow Variables, etc.
`code-execution`	Code Execution	Javascript Code, Python Code
`llm`	LLM	Generic LLM Prompt (non-Stacksync-branded)
`queues`	Queues	Insert Data, Consumer Trigger
`variables`	Variables	Workspace Variable CRUD

Partner Branding Rules¶

Module icons: stacksync* and file_service app types get partner icon. system modules keep their own icons (only the category header gets partner icon).
Category icons (in apps_branding): stacksync*, system, and file_service get partner icon.
Module names: "Stacksync" in module_name is replaced with partner name (e.g. "Stacksync AI" → "Rillet AI"). Modules without "Stacksync" in their name (e.g. "If Else", "Get File Content") keep their display name.

module_id Format¶

The module_id follows the pattern {app_type}-{action}-{variant}:

salesforce-get-records
stacksync-ai-summarize
system-if_else
system-http_requests
code-execution-javascript_v1
code-execution-python_v1

The resource table extracts the app type from module_id using split_part(module_id, '-', 1). This means: - stacksync-ai-summarize → stacksync (all stacksync sub-types collapse to stacksync) - salesforce-get-records → salesforce - code-execution-javascript_v1 → code-execution (special-cased to javascript in the SQL) - system-http_requests → system (special-cased to http in the SQL)

Table	Relationship
`apps_branding`	Maps `app_type` → display name, icon URL, metadata. Used for category headers in the module sidebar.
`workflows_versions`	`workflow_schema` jsonb contains array of module instances referencing `module_id`.
`workflows_apps_private`	Private/custom apps per workspace — their modules also appear in `workflows_modules`.
