Using the GraphQL API for Discussions

Learn how to use the GitHub Discussions GraphQL API.

In this article

The GitHub Discussions GraphQL API allows you to get, create, edit, and delete discussion posts. For more information about GitHub Discussions, see "‎About discussions."

This API is available for authenticated users, OAuth Apps, and GitHub Apps. Access tokens require the repo scope for private repositories and the public_repo scope for public repositories. For more information, see "Scopes for OAuth apps."

To use this API, you must include GraphQL-Features: discussions_api in the HTTP header.

Fields

Repository.discussions

List the discussions within a repository. If categoryId is specified, only results within that category will be returned.

Signature:

  first: Int,
  last: Int,
  categoryId: ID = null,
  orderBy: DiscussionOrder = {field: UPDATED_AT, direction: DESC}
) : Discussion

DiscussionOrder

"""
Ways in which discussions can be ordered.
"""
input DiscussionOrder {
  """
  The field by which to order discussions.
  """
  field: DiscussionOrderField!

  """
  The direction in which to order discussions by the specified field.
  """

"""
enum DiscussionOrderField {
  """
  Order discussions by creation time.
  """
  CREATED_AT

  """

  """
  UPDATED_AT
}

Repository.discussionCategories

Return the available discussion categories defined within this repository. Each repository may have up to 10 categories. For more information about discussion categories, see "About discussions."

Signature:

discussionCategories(
  after: String,
  before: String,
  first: Int,
  last: Int,
) : DiscussionCategoryConnection!

Repository.discussion

Get a discussion. Returns null if discussion with the specified ID exists.

Signature:

Repository.pinnedDiscussions

Return discussions pinned to this repository, ordered by pin position.

Signature:

pinnedDiscussions(
  after: String,
  before: String,
  first: Int,
  last: Int,
) : PinnedDiscussionConnection!

Objects

Note: For brevity, connection types are not expanded here. Each connection type mentioned in the schema follows the same pattern as other connections in the GraphQL API. For more information, see "Introduction to GraphQL."

Mutations

These mutations follow the same implementation pattern that other mutations in the GraphQL API. Each mutation accepts a single argument of an Input type, named after the mutation, and returns a Payload type containing the fields specified.

For example, this is a basic createDiscussion mutation that will create a new discussion:

mutation {
  # input type: CreateDiscussionInput
  createDiscussion(input: {repositoryId: "1234", categoryId: "5678", body: "The body", title: "The title"}) {

    # response type: CreateDiscussionPayload
    discussion {
      id
    }
  }
}

createDiscussion

Input fields:

  • body: String! The body of the new discussion.
  • title: String! The title of the new discussion.
  • repositoryId: ID! The ID of a repository in which to create the discussion.
  • categoryId: ID! The ID of a DiscussionCategory within this repository.
  • clientMutationId: String A unique identifier for the client performing the mutation.

Return type fields:

  • clientMutationId: String The unique identifier provided as an input.
  • discussion: Discussion The discussion that was created.

updateDiscussion

Input fields:

  • discussionId: ID! The node ID of the discussion to update.
  • body: String The new contents of the discussion body.
  • title: String The new discussion title.
  • categoryId: ID The node ID of a DiscussionCategory within the same repository to change this discussion to.
  • clientMutationId: String A unique identifier for the client performing the mutation.

Return type fields:

  • clientMutationId: String The unique identifier provided as an input.
  • discussion: Discussion The discussion that was modified.

deleteDiscussion

Input fields:

  • id: ID! The node ID of the discussion to delete.
  • clientMutationId: String A unique identifier for the client performing the mutation.

Return type fields:

  • clientMutationId: String The unique identifier provided as an input.
  • discussion: Discussion The discussion that was deleted.

addDiscussionComment

Input fields:

  • body: String! The contents of the comment.
  • discussionId: ID! The node ID of the discussion to comment on.
  • replyToId: ID The node ID of the discussion comment to reply to. If absent, the created comment will be a top-level comment.
  • clientMutationId: String A unique identifier for the client performing the mutation.

Return type fields:

  • clientMutationId: String The unique identifier provided as an input.
  • comment: DiscussionComment The discussion comment that was created.

updateDiscussionComment

Input fields:

  • body: String! The new contents of the comment body.
  • commentId: ID! The node ID of the discussion comment to update.
  • clientMutationId: String A unique identifier for the client performing the mutation.

Return type fields:

  • clientMutationId: String The unique identifier provided as an input.
  • comment: DiscussionComment The discussion comment that was updated.

deleteDiscussionComment

Input fields:

  • id: ID! The node ID of the discussion comment to delete.
  • clientMutationId: String A unique identifier for the client performing the mutation.

Return type fields:

  • clientMutationId: String The unique identifier provided as an input.
  • comment: DiscussionComment The discussion comment that was deleted.

markDiscussionCommentAsAnswer

Input fields:

  • id: ID! The node ID of the discussion comment to mark as an answer.
  • clientMutationId: String A unique identifier for the client performing the mutation.

Return type fields:

  • clientMutationId: String The unique identifier provided as an input.
  • discussion: Discussion The discussion that includes the chosen comment.

unmarkDiscussionCommentAsAnswer

Input fields:

  • id: ID! The node ID of the discussion comment to unmark as an answer.
  • clientMutationId: String A unique identifier for the client performing the mutation.

Return type fields:

  • clientMutationId: String The unique identifier provided as an input.
  • discussion: Discussion The discussion that includes the unmarked comment.

Discussion may be returned from the top-level search field. To search for discussion, specify type as DISCUSSION. The SearchResultItemConnection type has a discussionCount field to report the number of returned discussions, and the Discussion type is added to the SearchResultItem union.
