Triggers
When you create an automation you first answer “What should trigger this automation?” and pick one of three:Step 1 — Choose the content (Post / Story)
This step decides which posts or stories the automation watches. Comments trigger:- Specific posts or reels — pick exactly which ones (select at least one from the grid).
- Any post or reel — applies to all your posts.
- Upcoming posts — applies to everything you publish from now on.
Step 2 — Targeting & keywords
Decide which comments or messages qualify:- Comments / Messages containing specific keywords — only fires when the text contains one of your keywords.
- Any comment / Any message — fires on everything, regardless of content.
Auto-reply publicly to comments
Available only with the Comments trigger, this toggle lives in the Keywords step. When on, SocialSyncs posts a public reply under the comment.- Add up to 5 reply variants — one is picked at random each time so replies don’t look repetitive.
- Each variant can be up to 500 characters.
Step 3 — The DM flow (Actions)
The Actions step is titled “Set up your DM flow.” It has three toggles, run in order:Send a welcome message
An opening DM with a button the person taps to opt in (Instagram requires this opt-in before you can fully message someone).- Message — the main text, up to 640 characters, with personalization variables.
- Subtitle — optional, up to 80 characters.
- A fixed “Let’s Chat! 💬” button (label editable; the button itself can’t be removed).
Ask to follow first
Invites the person to follow you before continuing. Locked until “Send a welcome message” is enabled.- Message and Subtitle, same limits as above.
- Two fixed buttons: “Visit profile” and ”✅ I am following.”
- SocialSyncs verifies the follow before moving on, and skips this step if the person already follows you.
Send the primary DM
The main payoff message. Pick a DM format:
Each message/card supports up to 3 buttons, which can be a link (URL) or a quick reply (postback).
None of the three DM actions are mandatory. You can build a comment automation that only posts a public reply, or one that sends a single primary DM with no welcome step.
Personalize with variables
In any message field, use Insert to drop in a variable that’s filled per person:The available variables match the trigger — for the Story and DM triggers, the message text variable reads Story reply text / DM text instead of Comment text.
