Instagram lets apps publish only to professional accounts (Business or Creator). PostWire connects yours in one of two ways, both through PostWire's own Meta app (no developer app needed): log in with Instagram — no Facebook Page needed, approved by Meta on October 8, 2026 — or through the Facebook Page linked to your account (approved July 14, 2026). If several Instagram accounts are linked to your Pages, you pick which one PostWire posts to.
In the Instagram app: Profile → ☰ → Settings and activity → Account type and tools → Switch to professional account, then Creator or Business. Free, about a minute. No Facebook Page is needed for this option.
Open Accounts → Connect account → Instagram, Log in with Instagram is already selected: tick that the account is Business or Creator, press Continue to Instagram and sign in to the Instagram account you post to. Instagram asks to let PostWire read your profile and publish your content: press Allow.
From Claude or another AI agent: ask “connect my Instagram” and open the one-hour link it gives you.
You come back to PostWire with the account connected. If you are signed in to the wrong Instagram account in your browser, log out of it on instagram.com first, then connect again.
Use this if your Instagram account is already linked to a Facebook Page you manage, or if you also want to post to that Page.
In the Instagram app: Profile → ☰ → Settings and activity → Account type and tools → Switch to professional account, then pick Creator or Business. It is free and takes a minute. Personal accounts cannot be published to by any tool — that is Meta's rule.
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.
No Page yet? Create one at facebook.com/pages/create. You need to be an admin of the Page.
Open Accounts → Connect account → Instagram, press Use a Facebook Page instead, tick that the account is linked to a Page, and press Continue to Instagram. Facebook shows “Continue as <your name>”, then asks which Instagram accounts and Pages PostWire may use: tick your Instagram account and the Page it is linked to, then Save.
From Claude or another AI agent: ask “connect my Instagram” and open the one-hour link it gives you; the steps are the same.
If your Pages have more than one Instagram account, PostWire asks “Which Instagram account should PostWire post to?” with one button per account. Click yours: Meta usually skips its screen the second time, so it is one click. Each brand in PostWire posts to one Instagram account; to post to another, connect it under another brand.
That's it: you come back to PostWire with the account connected and can publish photos, Reels and carousels of up to 10 items.
This is Meta's error when linking a Page, and it happens a lot with new accounts. What fixes it, in order:
| Cause | Fix |
|---|---|
| The Instagram account is still personal | Switch to professional first (step 1), 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. |
| PostWire connected a different Instagram account | In Accounts, connect Instagram again and pick the right account, or tick only that account on Facebook's screen. |
