Node catalogue

Every node available in the builder, grouped as in the palette. And at the end, just as important: what LinkedFlow doesn't do.

Triggers — how people enter

Node	When it starts
Manual	Only when you press “Run”. The classic starting point.
Schedule	At the time you define (by default, weekdays at 9:00). It requires the next node to be a people search: it's the “every morning, search and feed the flow” pattern.
Prospect Added	Each prospect who enters the chosen list starts the journey.
CSV Imported	When an import finishes.
Webhook	An external POST (your CRM, Zapier, n8n…) with the workflow's token. It doesn't create prospects: it resolves an existing one by identifier, URL or email.
Connection Accepted	When someone accepts your invitation.
Message Received	When a DM arrives; the text comes in `{{trigger.message_text}}`.
Post Comment	When someone comments on a post of yours, with an optional keyword filter (“LEAD”, “INFO”…). It's polled every 5 minutes; the “Check the post now” button works even in draft.

Node	What it does
Search People	Feeds the flow with the results of a search (up to 50 per pass). It's a source node: it goes right after a trigger.
Get Profile	Reads the profile data without notifying the person. Doesn't spend quota.
Visit Profile	Visits with notification (“X viewed your profile”). Spends visit quota. The classic touch before inviting.
Send Invitation	With a personalised note or without one. If LinkedIn's note quota runs out, it retries once without the note and records it in the trail.
Wait For Connection	Pauses the journey until they accept. Outputs: accepted / time ran out (7 days by default) / withdrawn.
Withdraw Invitation	Withdraws a pending invitation (the elegant move before retrying cold later on).
Send Message	DM to a first-degree connection. With variants and variables.
Start Conversation	Opens a new thread; with an InMail option if your account allows it.
Wait For Reply	Outputs: replied / time ran out (7 days by default).
React to Message	Like on the last DM received.
React to Comment	Like on the comment that triggered the flow (after the comment trigger).
React to Post	Like (or celebrate, support, love…) on the prospect's latest post or a post by URL. The warm-up tool.
Reply to Comment	Public reply to the comment. Doesn't spend message quota: it only respects the global pause between actions.

Available reactions: LIKE, CELEBRATE, SUPPORT, FUNNY, LOVE, INSIGHTFUL.

Node	What it does
IF	Branches on a condition (`{{previous.score}} >= 60`, for example). Outputs: yes / no.
Switch	Several named outputs based on a variable's value.
Filter	Lets through only those who meet the condition; everyone else ends there.
Deduplicate	Blocks anyone who already passed through this point.
Merge	Joins several branches into one path.
Stop Prospect	Ends that person's journey, with a reason visible in the trail.
Stop Workflow	Ends the whole execution.

Node	What it does
Wait	A duration: `2h`, `1d`, `3d`… The engine resumes waits every minute.
Wait Until	A specific date/time.
Business Hours	Holds the step until the next business window (9:00–18:00 by default).
Rate Limit	Lets through at most N per day per account (20 by default) — a tap inside the workflow itself, on top of the account quotas.

Node	What it does
Human Approval	Pauses the journey and leaves the proposed message in the Approvals inbox, editable before sending. Outputs: approved / rejected.

Node	What it does
AI Agent	Reads the conversation and your knowledge base and drafts a reply; it can escalate to a human. It doesn't send: chain “Send Message” afterwards with `{{previous.text}}`.
AI Generate Message	Drafts a message from scratch following your instructions.
AI Personalize	Adapts a template to the prospect's profile.
AI Prospect Score	Scores the prospect's fit with your ICP (0–100), useful for branching afterwards.
AI Classify Reply	Classifies what they answered: POSITIVE, INTERESTED, QUESTION, NEUTRAL, NOT_NOW, NOT_INTERESTED or DO_NOT_CONTACT — each category is an output.

How the AI works (credits, providers, guardrails) is covered in AI Mode.

Node	What it does
Notify	Internal email to the workspace's managers (“X replied — interested!”).
Add To List	Moves/adds the prospect to a CRM list.
Tag	Adds tags to the prospect.
Webhook	Signed POST to your CRM or tool with the prospect's and the journey's data.
HTTP Request	Generic HTTP call to any API of yours.

So you don't look for it where it isn't — and because saying no is a product feature too:

It doesn't publish posts on your feed or schedule content.
It doesn't email prospects (emails are only internal alerts to your team; for your CRM you have the outgoing webhook).
It doesn't touch other networks: no WhatsApp, no Telegram, no Instagram, no X, no Facebook, no TikTok.
It doesn't make calls or send SMS.
It doesn't follow profiles or pages, and it doesn't act in LinkedIn groups.
It doesn't do mass scraping or bulk exports.
It doesn't run actions “as a company page” (companies are searched, not operated).
There is no “who viewed my profile” trigger.
