How Does an AutoDM Tool Work?
AutoDM tools work in three steps:
Step 1: Trigger Detection
A follower takes a specific action on your Instagram:
Comments a keyword on your Reel or Post (e.g., "LINK", "PRICE", "INFO")
Replies to your Story with any message
Mentions you (@yourusername) in their Story
Sends a keyword in your DMs directly
Step 2: API Processing
The AutoDM tool detects the trigger using the official Instagram Graph API (for safe, Meta-verified tools). This happens in real time — under 1 second with ReplyKaro.
Step 3: DM Sent Automatically
The tool instantly sends a pre-written DM to the triggering user. The message can include:
Links to resources, products, or lead magnets
Personalized text with the follower's name
Multiple messages in a sequence
Conditional messages based on follow status (Follow-Gate)
