# What's possible with timeline comments? ## What's possible * Reading timeline [comments](https://shopify.dev/docs/admin-api/graphql/reference/events/commentevent), and [other events](https://shopify.dev/docs/admin-api/graphql/reference/events/basicevent), for orders, draft orders, customers, and inventory transfers. * Writing order and customer *notes*. This is *not the same* as the timeline comments. We mention it here because this frequently makes for an acceptable fallback approach. ## What's not possible * Using a timeline event as a Mechanic event. This means that Mechanic tasks can't run in direct response to a new comment (or other timeline event). * Reading the name of the staff person who left a comment, or the name of the app responsible for another event. * Creating, updating, prefilling, or deleting timeline comments. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
