I did follow the docs and， however, it only update the topic’s title, without updating the body. My code (Javascript): async function updateDiscourseTopic(topic_id) { const Discourse_API_Key = "Discourse_API_Key"; const url = `https://discourse.mysite.com/t/-/${topic_id}.json`; const payload = { title: 'session_1', raw: "new body(doesn't apply)" } const response = await fetch(url, { method: 'PUT', headers: { "Api-Key": Discourse_API_Key, "Api-Username": "system", "Content-Type": "application/json", }, body: JSON.stringify(payload) }); }

@Lilly’s right. A topic is defined by attributes like title, category, tags, etc. But the content belongs to a post. If you want to update the title and the content, you need 2 requests. PUT on the topic PUT on the first post. You can find the post’s ID in the HTML code of the page. Look for the data-post-id attribute in . Example:

Wow，you are right, it works :sparkling_heart: And I figured out how to retrieve the ID of the first post in a topic using the Discourse API: async function getFirstPostIdFromOnetopic(topic_id) { const Discourse_API_Key = "Discourse_API_Key"; const url = `https://discourse.mysite.com/t/${topic_id}/posts.json`; const response = await fetch(url, { method: 'GET', headers: { "Api-Key": Discourse_API_Key, "Api-Username": "system", "Content-Type": "application/json", } }); const data = await response.json(); const firstPostId = data.post_stream.posts[0].id; return firstPostId; } Thank you and @Lilly :innocent:

just a guess from looking at the code, but perhaps it may be because you are using topic_id instead of post_id? because first post is the topic in Discourse, more or less?
