Token auto-refresh: why it matters and how we handle it

When you connect Instagram, Facebook, or LinkedIn to a scheduler, you're giving a time-limited token. When it expires, posts can fail and connections drop. We explain why this happens and how Post See refreshes tokens so you never lose access mid-campaign.

Quick summary

Social platforms expire your connection tokens—so "Connect once, post forever" only works if refresh is automatic. Real use case: users who switched from tools that didn't refresh lost access mid-campaign. Here's how we keep your accounts connected.

Use cases

Campaign that didn't miss a beat

100% delivery

A brand ran a 30-day campaign with daily posts. Their previous tool had dropped the connection in week 2 without warning. With auto-refresh, all 30 posts went out; they only learned about token expiry from our docs.

Agency with 20+ client accounts

Zero re-auth hassle

Managing tokens for 20 Instagram accounts manually would be a nightmare. Auto-refresh means the agency connects once per client and doesn't have to re-auth every few months.

Creator who forgot about tokens

Set and forget

She hadn't thought about OAuth until her old scheduler failed. She switched to a tool that refreshes; her accounts stayed connected and she didn't lose a single scheduled post.

How it works

How token refresh works (simplified)

When you connect, we store a refresh token. Before your access token expires, we use the refresh token to get a new one. You never see this—it happens in the background. If refresh fails (e.g. you revoked app access), we notify you to reconnect.

1
You connect an account (we get access + refresh tokens)
2
Before access expires, we call the platform's refresh endpoint
3
New access token is stored; posting continues
4
If refresh fails, we alert you and pause posting until you reconnect

Frequently asked questions

Short answers based on this guide—helpful for readers and search.

What is an OAuth token in plain language?
It is a time-limited permission slip from Instagram, Facebook, LinkedIn, or another network that lets Post See publish on your behalf after you sign in. It is not your password; it expires or can be revoked, which is why refresh and reconnect flows matter.
Why does token auto-refresh matter for scheduled campaigns?
If access expires mid-campaign, posts can fail without a clear warning in your head. Auto-refresh swaps in new tokens in the background when platforms allow it, so long-running schedules and agencies with many client accounts see fewer surprise drop-offs.
Do I still need to reconnect if I change my password or revoke the app?
Yes. Password changes, security resets, or revoking the app on the social network break the old token. You reconnect from your scheduler’s connections screen; auto-refresh cannot override a revocation you initiated on the platform.
Is token handling different for users in the EU or UK?
OAuth is global, but platforms sometimes change consent screens or data rules by region. The underlying idea is the same: you approve access on the official site, and the tool stores tokens under its privacy policy. If you operate in the EU or UK, keep records of which apps have access to your business pages for compliance hygiene.
