Commits

Signature verification object

The response will include a verification object that describes the result of verifying the commit's signature. The following fields are included in the verification object:

Name	Type	Description
verified	boolean	Indicates whether GitHub considers the signature in this commit to be verified.
reason	string	The reason for verified value. Possible values and their meanings are enumerated in table below.
signature	string	The signature that was extracted from the commit.
payload	string	The value that was signed.

These are the possible values for reason in the verification object:

Value	Description
expired_key	The key that made the signature is expired.
not_signing_key	The "signing" flag is not among the usage flags in the GPG key that made the signature.
gpgverify_error	There was an error communicating with the signature verification service.
gpgverify_unavailable	The signature verification service is currently unavailable.
unsigned	The object does not include a signature.
unknown_signature_type	A non-PGP signature was found in the commit.
no_user	No user was associated with the committer email address in the commit.
unverified_email	The committer email address in the commit was associated with a user, but the email address is not verified on their account.
bad_email	The committer email address in the commit is not included in the identities of the PGP key that made the signature.
unknown_key	The key that made the signature has not been registered with any user's account.
malformed_signature	There was an error parsing the signature.
invalid	The signature could not be cryptographically verified using the key whose key-id was found in the signature.
valid	None of the above errors applied, so the signature is considered to be verified.

Protected branches are available in public repositories with GitHub Free and GitHub Free for organizations, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud, and GitHub Enterprise Server. For more information, see GitHub's products in the GitHub Help documentation.

Returns all branches where the given commit SHA is the HEAD, or latest commit for the branch.

Lists the merged pull request that introduced the commit to the repository. If the commit is not present in the default branch, will only return open pull requests associated with the commit.

To list the open or merged pull requests associated with a branch, you can set the commit_sha parameter to the branch name.

Returns the contents of a single commit reference. You must have read access for the repository to use this endpoint.

Note: If there are more than 300 files in the commit diff, the response will include pagination link headers for the remaining files, up to a limit of 3000 files. Each page contains the static commit information, and the only changes are to the file listing.

You can pass the appropriate media type to fetch diff and patch formats. Diffs with binary data will have no patch property.

To return only the SHA-1 hash of the commit reference, you can provide the sha custom media type in the Accept header. You can use this endpoint to check if a remote reference's SHA-1 hash is the same as your local reference's SHA-1 hash by providing the local SHA-1 reference as the ETag.

Signature verification object

The response will include a verification object that describes the result of verifying the commit's signature. The following fields are included in the verification object:

Name	Type	Description
verified	boolean	Indicates whether GitHub considers the signature in this commit to be verified.
reason	string	The reason for verified value. Possible values and their meanings are enumerated in table below.
signature	string	The signature that was extracted from the commit.
payload	string	The value that was signed.

These are the possible values for reason in the verification object:

Value	Description
expired_key	The key that made the signature is expired.
not_signing_key	The "signing" flag is not among the usage flags in the GPG key that made the signature.
gpgverify_error	There was an error communicating with the signature verification service.
gpgverify_unavailable	The signature verification service is currently unavailable.
unsigned	The object does not include a signature.
unknown_signature_type	A non-PGP signature was found in the commit.
no_user	No user was associated with the committer email address in the commit.
unverified_email	The committer email address in the commit was associated with a user, but the email address is not verified on their account.
bad_email	The committer email address in the commit is not included in the identities of the PGP key that made the signature.
unknown_key	The key that made the signature has not been registered with any user's account.
malformed_signature	There was an error parsing the signature.
invalid	The signature could not be cryptographically verified using the key whose key-id was found in the signature.
valid	None of the above errors applied, so the signature is considered to be verified.

Compares two commits against one another. You can compare branches in the same repository, or you can compare branches that exist in different repositories within the same repository network, including fork branches. For more information about how to view a repository's network, see "Understanding connections between repositories."

This endpoint is equivalent to running the git log BASE..HEAD command, but it returns commits in a different order. The git log BASE..HEAD command returns commits in reverse chronological order, whereas the API returns commits in chronological order. You can pass the appropriate media type to fetch diff and patch formats.

The API response includes details about the files that were changed between the two commits. This includes the status of the change (if a file was added, removed, modified, or renamed), and details of the change itself. For example, files with a renamed status have a previous_filename field showing the previous filename of the file, and files with a modified status have a patch field showing the changes made to the file.

When calling this endpoint without any paging parameter (per_page or page), the returned list is limited to 250 commits, and the last commit in the list is the most recent of the entire comparison.

Working with large comparisons

To process a response with a large number of commits, use a query parameter (per_page or page) to paginate the results. When using pagination:

• The list of changed files is only shown on the first page of results, but it includes all changed files for the entire comparison.
• The results are returned in chronological order, but the last commit in the returned list may not be the most recent one in the entire set if there are more pages of results.

For more information on working with pagination, see "Using pagination in the REST API."
