Mastodon

Authentication Method

Mastodon is federated, meaning each instance has separate OAuth:

1. User provides their instance URL (e.g., mastodon.social)
2. TendSocial registers as an app on that instance (dynamically)
3. User authorizes through their instance

Current Implementation

Users enter their Mastodon instance before OAuth. TendSocial carries that instance through OAuth state and stores it in account metadata for publishing. The launch flow uses configured client credentials for the selected instance; do not promise automatic dynamic app registration for every Mastodon instance until per-instance client registration is implemented and verified end to end.

Required Scopes

Scope	Purpose
read	Read account info
write	Post toots
follow	Follow, boost, and favorite workflows
push	Receive notifications (future optional scope)

Callback URL

https://api.tendsocial.com/api/company/social-accounts/callback/MASTODON

Environment Variables

Mastodon credentials are per-instance, stored in database per connection.

Optional default instance:

MASTODON_CLIENT_ID=your_client_id
MASTODON_CLIENT_SECRET=your_client_secret
MASTODON_INSTANCE_URL=mastodon.social

Bluesky

Authentication Method

Bluesky uses App Passwords (not OAuth):

1. Go to Bluesky Settings
2. Click Add App Password
3. Name it (e.g., "TendSocial")
4. Copy the generated password

IMPORTANT

Bluesky does not support OAuth. Users provide their handle and app password directly.

API Endpoint

https://bsky.social/xrpc/

Or the user's PDS if self-hosted:

https://{user-pds}/xrpc/

Required Credentials

Credential	Format
Handle	username.bsky.social or custom domain
App Password	Generated app-specific password

Environment Variables

Bluesky credentials are per-user, stored in database.

No global environment variables needed.

Character Counting

Bluesky counts graphemes, not bytes or characters:

• Emoji = 1 grapheme (regardless of modifiers)
• Links are counted at full length
• Mentions/hashtags counted at full length

TendSocial handles grapheme counting automatically.
