Start with one task
Pick a repeated request and prepare one useful reply. The goal is to confirm that the right person receives the right message, not to create the largest number of flows.
Prepare the workspace
Verify your email, set a password and add your business details. Connect the right Instagram account through the authorization screen. Never put an Instagram password into a message template.
Run a limited test
Choose one post and one keyword. Save the flow, then leave a new comment from an eligible test account. Meta app access and permissions affect live delivery; an editor preview does not confirm them.
Check both success and boundaries
Verify the intended keyword and an unrelated comment. Check links on a phone and look in message requests if needed. If delivery fails, record the post link and test time for support, not passwords or tokens. Expand gradually after a successful test.
