Instagram Business Login: connect without a Facebook Page

Sellers who run on Instagram alone can now connect directly, no Facebook Page required. The OAuth flow auto-discovers a linked Instagram account when a Page is already connected.

Not every social seller has a Facebook Page. Plenty run everything from Instagram. InboxCart now supports Instagram Business Login as a standalone path: connect the Instagram account, skip the Page entirely.

What's new

  • Standalone Instagram Business Login: uses api.instagram.com and graph.instagram.com with its own Meta sub-app.
  • Auto-discovery: if a seller connects Facebook first, any linked Instagram account is detected and enabled automatically.
  • Dual-path settings UI: sellers see either the OAuth button or a manual token entry fallback depending on which Meta products they have provisioned.

Why it matters

The original flow assumed a Facebook Page. That assumption excluded a large chunk of Instagram-native sellers. This change makes InboxCart genuinely Instagram-first for businesses that live there.
