Instagram only lets apps publish to professional accounts (Business or Creator). PostWire can connect one in two ways: through a Facebook Page linked to it, or by logging in with Instagram directly, with no Page at all.
In the Instagram app: Profile → ☰ → Settings and activity → Account type and tools → Switch to professional account, then pick Creator or Business. Personal accounts cannot be published to by any tool — this is Meta's rule, not ours.
If Instagram shows the wrong account, log out of it on instagram.com first and try again — Instagram connects whichever account is logged in in that browser.
From the Instagram app (most reliable): Profile → Edit profile → Page → Connect or create → choose your Page.
From Facebook on a computer: switch into your Page's profile → Settings → Linked accounts → Instagram → Connect account.
This is Meta's error, and it happens a lot with new accounts. What actually fixes it, in order:
| Cause | Fix |
|---|---|
| The Instagram account is still personal | Switch to professional first (top of this page), then link. |
| It is already linked to another (or a deleted) Page | Instagram → Edit profile → Page → disconnect it, then connect the right one. Instagram allows one Page at a time. |
| You are not an admin of the Page | An admin must give you full control of the Page, then retry. |
| Linking from Accounts Center fails | Do it from the Instagram app (Edit profile → Page) instead — it uses a different path. |
| Brand-new account, nothing works | Skip the Page entirely: use Option 1 · Log in with Instagram. |
