Setup guide: zero to first DM in 5 minutes

1. Create your account

Go to /auth/sign-up, enter an email and password. We don't require credit card details for the Free plan.

2. Create a Facebook Developer App

Visit developers.facebook.com/apps and click Create App.

• App type: Business
• Name: anything (e.g. "My Comment 2 Chat")
• Add the Instagram Graph API and Facebook Login for Business products

From the App Settings page, copy your App ID and App Secret.

3. Add the redirect URI

Inside Facebook Login for Business → Settings, add the OAuth redirect URI we display on the Connections page:
https://comment2chat.online/api/meta/callback

4. Paste credentials into comment2chat.online

In your dashboard, go to Connections and paste your App ID and App Secret. Click Save. The credentials are encrypted at rest in our database.

5. Connect Instagram

Click Connect with Facebook. Log in, pick the Facebook Page connected to your IG Business account, grant permissions. Done — you should see your Instagram username appear under Connected accounts.

6. Build your first workflow

Open Automations → New, drop a Trigger node, set it to "Comment contains GUIDE", then add a DM action with your message. Toggle the workflow Active and save.

Comment GUIDE on one of your posts from another account. Within a few seconds you should see the DM arrive. If something fails, check /dashboard/logs.

Troubleshooting

• OAuth error: "Invalid redirect URI" — the URI in Meta must match exactly, no trailing slash.
• No Instagram accounts shown — your IG account must be a Business or Creator account and connected to a Facebook Page.
• DM not delivered — Meta's 24-hour window: the trigger comment is what opens it. Test with a fresh comment.
