Do I need a Meta app to post to my own Instagram with Postwire?

No. The extension fills the post in Instagram's web composer and you click publish. App review only matters if you build an app that posts for other people.

Why use the Chrome extension instead of Meta's API?

The API path costs a developer app, permissions and token upkeep. Filling the web composer needs none of that; the trade-off is that your Mac must be awake and you click publish on every post.

How often do tokens need refreshing?

Only if you connected a Meta app for metrics: long-lived tokens last weeks, not forever, and Postwire warns seven days before each one expires. Posting does not use them.

Meta APIs for Instagram, Threads and Facebook: what an unreviewed app can do, and why Postwire skips it

Postwire is a social media auto poster that fills your own Instagram, Threads and Facebook posts in their web composers so you click publish, with no Meta app required.

What works without app review

A Meta app that has not been through app review can still be used by people who have a role on it, such as admins, developers and Testers. If the Instagram, Threads and Facebook accounts you want to post to are your own, giving them a role on the app is generally enough to publish through the official APIs.

Postwire used to work this way. Since November 2026 it does not post through Meta's APIs at all: the Chrome extension fills the Threads, Instagram and Facebook composers in your logged-in ops profile and you click publish, so you never have to create or maintain a Meta app.

What does not

Posting for accounts that do not have a role on your app, which is what a product serving other people would need, requires Meta's app review and business verification. Postwire does not do that and does not post for other people's accounts.

Rules differ by API and change over time, so check Meta's current developer documentation for permissions and review requirements before you rely on them.

Where a Meta app still helps

A Meta app is now optional and only used to pull engagement metrics. If you connect one, Postwire stores its long-lived tokens encrypted and alerts you seven days before expiry; without one, posting works the same and metrics are skipped. Either way, Instagram needs at least one image (carousels up to 10) and has no clickable caption links, and Threads allows 500 characters.
