PostHog Errors to Linear: common questions

Doesn't PostHog already integrate with Linear?

It does, but you create each issue yourself. This workflow files every new error automatically every morning, under one parent ticket, and tells you in Slack.

Does it fix the errors?

No. It finds new errors and files them as tickets so your team can pick them up. It doesn't change any code.

Will it file the same error twice?

No. Before filing, it checks the sub-tickets already under your parent ticket and skips errors that are there.

Is there an n8n template for this?

You don't need one. This workflow is already built: connect your apps and it runs, with nothing to wire up or host.

Which apps do I need to connect?

Linear, PostHog and Slack. You connect each one once, in a click, when you set the workflow up.

Can I change the schedule or the steps?

Yes. Installing copies the whole workflow into your workspace as a draft, and from then on it's yours: reword any step, change the settings, and pick the schedule and time zone (it suggests daily, 6 am). Nothing runs until you run it or publish it.

Which AI model runs it?

The agent you choose when you install it. The workflow uses that agent's model, tools and memory, and you can move it to another agent later.
