# First Comment

Blotato posts a First Comment immediately after an Instagram or Facebook post publishes. First Comments work for posts published now and posts scheduled for later. The feature is available on every paid plan.

Use a First Comment for a link, additional context, or information you want outside the main caption.

## Using the Blotato Web App

1. Create an Instagram or Facebook post.
2. Open the platform options.
3. Enter your text in **First Comment**.
4. Publish the post now or schedule it.
5. Blotato publishes the comment after the post goes live.

## Using the Blotato API or MCP

1. Add `target.firstComment` to an Instagram or Facebook request in [Publish Post](/rest-api-reference/publish-post.md).
2. For MCP, pass `firstComment` to `blotato_create_post`.
3. Submit the post for immediate publishing or scheduling.

Facebook First Comments support up to 8,000 characters. Instagram First Comments support up to 2,200 characters. First Comments work on Facebook posts and reels, plus Instagram posts, carousels, and reels. Stories do not support First Comments.

For another platform, wait for the post to publish, then use [Post Comment](/rest-api-reference/comments.md#post-comment) where supported or comment on the social platform.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.blotato.com/web-app-features/first-comment.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
