# Discussions API **(FREE)**

Discussions are a set of related notes on:

- Snippets
- Issues
- [Epics](../user/group/epics/index.md)
- Merge requests
- Commits

This includes [comments and threads](../user/discussions/index.md) and system notes.
System notes are notes about changes to the object (for example, when a milestone changes).
Label notes are not part of this API, but recorded as separate events in
[resource label events](resource_label_events.md).

## Discussions pagination

By default, `GET` requests return 20 results at a time because the API results are paginated.

Read more on [pagination](rest/index.md#pagination).

## Issues

#### Create a new thread on the overview page

```shell
curl --request POST --header "PRIVATE-TOKEN: <your_access_token>" \
  "https://gitlab.example.com/api/v4/projects/5/merge_requests/11/discussions?body=comment"
```

#### Create a new thread in the merge request diff

- Both `position[old_path]` and `position[new_path]` are required and must refer
  to the file path before and after the change.
- To create a thread on an added line (highlighted in green in the merge request diff),
  use `position[new_line]` and don't include `position[old_line]`.
- To create a thread on a removed line (highlighted in red in the merge request diff),
  use `position[old_line]` and don't include `position[new_line]`.
- To create a thread on an unchanged line, include both `position[new_line]` and
  `position[old_line]` for the line. These positions might not be the same if earlier
  changes in the file changed the line number. For the discussion about a fix, see
  [issue 32516](https://gitlab.com/gitlab-org/gitlab/-/issues/325161).
- If you specify incorrect `base`, `head`, `start`, or `SHA` parameters, you might run
  into the bug described in [issue #296829)](https://gitlab.com/gitlab-org/gitlab/-/issues/296829).

1. Create a new diff thread. This example creates a thread on an added line:

   ```shell
   curl --request POST --header "PRIVATE-TOKEN: <your_access_token>"\
     --form 'position[position_type]=text'\
     --form 'position[base_sha]=<use base_commit_sha from the versions response>'\
     --form 'position[head_sha]=<use head_commit_sha from the versions response>'\
     --form 'position[start_sha]=<use start_commit_sha from the versions response>'\
     --form 'position[new_path]=file.js'\
     --form 'position[old_path]=file.js'\
     --form 'position[new_line]=18'\
     --form 'body=test comment body'\
     "https://gitlab.example.com/api/v4/projects/5/merge_requests/11/discussions"
   ```

#### Parameters for multiline comments

Parameters for multiline comments only:

| Attribute                                | Type           | Required | Description |
| ---------------------------------------- | -------------- | -------- | ----------- |
| `position[line_range][end][line_code]`   | string         | yes      | [Line code](#line-code) for the end line. |
| `position[line_range][end][type]`        | string         | yes      | Use `new` for lines added by this commit, otherwise `old`. |
| `position[line_range][start][line_code]` | string         | yes      | [Line code](#line-code) for the start line. |
| `position[line_range][start][type]`      | string         | yes      | Use `new` for lines added by this commit, otherwise `old`. |
| `position[line_range][end]`              | hash           | no       | Multiline note ending line. |
| `position[line_range][start]`            | hash           | no       | Multiline note starting line. |

#### Line code

A line code is of the form `<SHA>_<old>_<new>`, like this: `adc83b19e793491b1c6ea0fd8b46cd9f32e292fc_5_5`

- `<SHA>` is the SHA1 hash of the filename.
- `<old>` is the line number before the change.
- `<new>` is the line number after the change.

For example, if a commit (`<COMMIT_ID>`) deletes line 463 in the README, you can comment
on the deletion by referencing line 463 in the *old* file:

```shell
curl --request POST --header "PRIVATE-TOKEN: [ACCESS_TOKEN]" \
  --form "note=Very clever to remove this unnecessary line!" \
  --form "path=README" --form "line=463" --form "line_type=old" \
  "https://gitlab.com/api/v4/projects/47/repository/commits/<COMMIT_ID>/comments"
```

If a commit (`<COMMIT_ID>`) adds line 157 to `hello.rb`, you can comment on the
addition by referencing line 157 in the *new* file:

```shell
curl --request POST --header "PRIVATE-TOKEN: [ACCESS_TOKEN]" \
  --form "note=This is brilliant!" --form "path=hello.rb" \
  --form "line=157" --form "line_type=new" \
  "https://gitlab.com/api/v4/projects/47/repository/commits/<COMMIT_ID>/comments"
```
