X Poster

X Poster is the X (formerly Twitter) component that acts with your account: it publishes new posts or replies, likes and unlikes, retweets and undoes retweets, and deletes your posts.

It is useful to take to X what happens in other processes, for example to publish every new blog article automatically, or to let an AI agent handle part of your account’s activity.

When to use it

You want to post on X every new article on your blog with a text an agent writes.
You want to reply to a specific post from a flow.
You want to retweet or like your own company’s posts from a department’s account.
You need to remove a post that went out with a mistake.

Configuration

You need an X API credential with the keys of a project in the X developer portal: X API Key, X API Secret Key, X Bearer Token, X Access Token and X Access Token Secret. To post, the app must have read and write permission. See Credentials.

Field	What it does
Credential (required)	The X API credential of the account that acts.
Operation (required)	What the component does. See Operations. Default: `Post Tweet`.
Mode	Only in `Post Tweet`. `Basic` publishes a new post; `Advanced` also shows Tweet ID so you can post a reply. Default: `Basic`.
Tweet Text	Only in `Post Tweet`. The text of the post. Required.
Tweet ID	Only in `Post Tweet` with `Advanced`. The ID of the post you want to reply to. If you leave it empty, a new post is published.
Tweet ID	In the other operations. The ID of the post the action applies to. It is the number at the end of its link. Required.
Username	Only in `Like Tweet`, `Retweet`, `Unlike Tweet` and `Delete Retweet`. The username of the credential’s account, without the @. Required.

Operations

Operation	What it does
`Post Tweet`	Publishes a new post or, with Tweet ID, a reply to another post.
`Like Tweet`	Likes a post.
`Retweet`	Retweets a post.
`Delete Tweet`	Deletes a post from the credential’s account.
`Unlike Tweet`	Removes the like from a post.
`Delete Retweet`	Undoes the retweet of a post.

Output

The Tweet Data output returns X’s answer. In Post Tweet it includes the ID and text of the new post; in the other operations, a confirmation of the action, for example whether the post is now liked or retweeted.

You can connect the result to a spreadsheet to keep a log of what was posted, or to a messaging component to tell the team. The component can also be connected to an Agent as a tool. See Tool Mode.

Example

An online store announces every new blog article on X.

The flow receives the new article’s title and link.
An agent writes a short message with the title and the link.
Add X Poster with the Post Tweet operation and the store’s X API credential.
Connect the agent’s message to Tweet Text.
Keep the ID from the Tweet Data output in case you need to delete the post later.

Good practices

Check the length of the text: X rejects posts that go over its character limit.
Actions are always made with the credential’s account. To act with another account, create another credential.

X Reader: look up posts and activity on X.
