I built a Friday morning Slack bot that tells me what I posted this week, what's scheduled, and what's missing — so I always have time to get ahead. Then I built a whole LinkedIn analytics app on Lovable. The API made both possible without writing code from scratch.

I wanted the power-user features Buffer hasn't built yet — thread splitting, a content calendar with planning notes, a snippet library. So I built PostIQ on top of the API. It's free, it connects in seconds, and it's everything I wished Buffer had out of the box.

A lot of my users were already posting through Buffer. When I started getting into it myself, I fell in love with the experience and the support — really, one of a kind. Now WriteStack users can send any Substack note to social using Buffer.

To create an API key or App Client and to view your API limits, you'll need to be an organization owner in your Buffer account. These will only be visible to you and not your teammates. We will be looking to extend permissions for this in the future.
