# st.doForPosts

This action allows you to apply the actions specified in its `then` parameter to each post provided by the parent action.

> There is a limit of 20 posts that this action can be applied to. If the parent action provides more than 20 posts, only the first 20 will be processed.

> Post-scoped actions can be nested directly under `st.doForPosts`, or wrapped in [st.openPost](/docs/action-st-open-post) first when you also need the post's data or want to run several post-scoped actions together for each post.

## Constraints

> ⏺️ **Root Start:** not allowed.

> ⬆️ **Parent Actions:** [st.retrieveCompanyPosts](/docs/action-st-retrieve-company-posts), [st.retrievePersonPosts](/docs/action-st-retrieve-person-posts).

> ⬇️ **Child Actions:** [st.openPost](/docs/action-st-open-post), [st.reactToPost](/docs/action-st-react-to-post), [st.commentOnPost](/docs/action-st-comment-on-post), [st.retrievePostComments](/docs/action-st-retrieve-post-comments), [st.retrievePostReactions](/docs/action-st-retrieve-post-reactions).

## Parameters

```json
{
  "actionType": "st.doForPosts",
  "then": { ... }
}
```

- `then` – object or array of child actions to apply to each post from the parent action.

## Result options

This action doesn't produce its own distinct result. The effects are visible in the posts that were involved, as they will contain a `then` field with the results of the applied actions. See usage examples for more details.
