Instagram error 200: This person isn't available right now

Code 200 with subcode 1545041 means Meta refused to deliver to this particular person, and it will not tell you exactly why. The documented message - "This person isn't available right now." - is deliberately vague because the reasons are privacy-sensitive: the account may be deactivated or deleted, restricted by Instagram, or the person may have blocked the business or tightened who can message them. The same string also appears under code 551, which is the block-shaped variant of the same refusal.

The defining property is that it is recipient-specific: the identical payload delivers to other IGSIDs. That distinguishes it cleanly from token errors (190, everything fails) and from permission or window errors (200 base, 10/2534022, which name their cause). Treat it as a hard per-recipient stop. Retrying does not help, and repeatedly messaging people who cannot receive from you is exactly the behavior Meta's integrity systems watch for.

Build a suppression list keyed on this subcode and honor it everywhere sends originate, so one unreachable recipient cannot generate a stream of refused calls. A rising rate of 1545041 across your audience is a quality signal worth investigating - it often tracks content people did not opt into. The sibling refusals are 551 and 10/2018108; the messaging-window rules that govern legitimate re-contact are in the limits reference.
