How do I list WordPress post categories?

Short answer: You can list categories in WordPress by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the WordPress List Categories action to a workflow, map its 0 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about List Categories.

What does the List Categories action do in WordPress?
Lists all post categories on the WordPress site with slug, name, and post count. Use to populate a category picker before posting.
What inputs does List Categories require?
List Categories has no required inputs. Sensible defaults are applied if you leave fields blank.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if WordPress returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does List Categories support batch operations?
Yes. Run List Categories inside a Loop node to process arrays. TinyCommand handles WordPress's rate limits automatically so you don't have to throttle manually.
