# Discussions API **(FREE)**
Discussions are a set of related notes on:
- Snippets
- Issues
- Epics **(ULTIMATE)**
- Merge requests
- Commits
This includes system notes, which are notes about changes to the object (for example,
when a milestone changes, a corresponding system note is added). 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](index.md#pagination).
## Issues

### Create new merge request thread
> The `commit id` entry was [introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/47130) in GitLab 13.7.
Creates a new thread to a single project merge request. This is similar to creating
a note but other comments (replies) can be added to it later.
```plaintext
POST /projects/:id/merge_requests/:merge_request_iid/discussions
```
Parameters for all comments:
| Attribute | Type | Required | Description |
| ---------------------------------------- | -------------- | -------- | ----------- |
| `id` | integer/string | yes | The ID or [URL-encoded path of the project](index.md#namespaced-path-encoding) |
| `merge_request_iid` | integer | yes | The IID of a merge request |
| `body` | string | yes | The content of the thread |
| `commit_id` | string | no | SHA referencing commit to start this thread on |
| `created_at` | string | no | Date time string, ISO 8601 formatted, such as `2016-03-11T03:45:40Z` (requires administrator or project/group owner rights) |
| `position` | hash | no | Position when creating a diff note |
| `position[base_sha]` | string | yes | Base commit SHA in the source branch |
| `position[start_sha]` | string | yes | SHA referencing commit in target branch |
| `position[head_sha]` | string | yes | SHA referencing HEAD of this merge request |
| `position[position_type]` | string | yes | Type of the position reference', allowed values: `text` or `image` |
| `position[new_path]` | string | yes (if the position type is `text`) | File path after change |
| `position[new_line]` | integer | no | Line number after change (for `text` diff notes) |
| `position[old_path]` | string | yes (if the position type is `text`) | File path before change |
| `position[old_line]` | integer | no | Line number before change (for `text` diff notes) |
| `position[line_range]` | hash | no | Line range for a multi-line diff note |
| `position[width]` | integer | no | Width of the image (for `image` diff notes) |
| `position[height]` | integer | no | Height of the image (for `image` diff notes) |
| `position[x]` | float | no | X coordinate (for `image` diff notes) |
| `position[y]` | float | no | Y coordinate (for `image` diff notes) |
#### 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. This is a bug that we plan to fix in
[GraphQL `createDiffNote` forces clients to compute redundant information (#325161)](https://gitlab.com/gitlab-org/gitlab/-/issues/325161).
- If you specify incorrect `base`/`head`/`start` `SHA` parameters, you might run
into the following bug:
[Merge request comments receive "download" link instead of inline code (#296829)](https://gitlab.com/gitlab-org/gitlab/-/issues/296829).
To create a new thread:
1. [Get the latest merge request version](merge_requests.md#get-mr-diff-versions):
```shell
curl --header "PRIVATE-TOKEN: <your_access_token>"\
"https://gitlab.example.com/api/v4/projects/5/merge_requests/11/versions"
```
1. Note the details of the latest version, which is listed first in the response array.
```json
[
{
"id": 164560414,
"head_commit_sha": "f9ce7e16e56c162edbc9e480108041cf6b0291fe",
"base_commit_sha": "5e6dffa282c5129aa67cd227a0429be21bfdaf80",
"start_commit_sha": "5e6dffa282c5129aa67cd227a0429be21bfdaf80",
"created_at": "2021-03-30T09:18:27.351Z",
"merge_request_id": 93958054,
"state": "collected",
"real_size": "2"
},
"previous versions are here"
]
```
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][start]` | hash | no | Multiline note starting line |
| `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][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`. |
#### 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"
```
