How Channels Are Connected

PostSider supports two connection methods. The method available depends on the platform.

​
OAuth (most platforms)

Most platforms use OAuth, which means PostSider handles the secure authentication handshake for you.
1

Open Add Channel

Navigate to Channels in the sidebar and click Add Channel.
2

Choose your platform

Select the platform you want to connect from the list.
3

Authenticate

Click Sign in with [Platform]. You’ll be redirected to that platform to authorize PostSider. After approving, you’re returned to PostSider with the channel connected.
OAuth platforms (such as X, LinkedIn, and Facebook) use app credentials that are set as environment variables on your instance. On PostSider Cloud they are already configured, so you can connect right away. If you self-host, add each platform’s Client ID and Secret to your .env first (see Environment).

​
Credential Paste (direct entry)

Some platforms don’t use a central OAuth server - or they offer simpler token-based access. For these, you enter your credentials directly into the Add Channel form. No app registration or server configuration is required. Platforms using direct credential entry include:
Credential-paste platforms are often the quickest to connect - there’s no OAuth app registration involved. Just generate a token from the platform’s settings page and paste it into PostSider.
Telegram, Farcaster, and Discord use bespoke connect flows instead of plain OAuth or credential paste. Telegram links the operator-configured shared bot with a /connect <code> flow, Farcaster uses Sign In With Neynar, and Discord offers a shared-bot OAuth path or bring-your-own bot token. See Messaging channels and Social Media for those instructions.
