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 run history shows the failed step with its input and the error message WordPress returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does List Categories support batch operations?
Run List Categories inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within WordPress's rate limits.
