Use the REST API to interact with tag objects in your Git database on GitHub.
A Git tag is similar to a Git reference, but the Git commit that it points to never changes. Git tags are helpful when you want to point to specific releases. These endpoints allow you to read and write tag objects to your Git database on GitHub. The API only supports annotated tag objects, not lightweight tags.
Note
Most endpoints use Authorization: Bearer <YOUR-TOKEN> and Accept: application/vnd.github+json headers, plus X-GitHub-Api-Version: 2026-03-10. Curl examples below omit these standard headers for brevity.
POST /repos/{owner}/{repo}/git/tags
Note that creating a tag object does not create the reference that makes a tag in Git. If you want to create an annotated tag in Git, you have to do this call to create the tag object, and then create the refs/tags/[tag] reference. If you want to create a lightweight tag, you only have to create the tag reference - this call would be unnecessary.
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:
NameTypeDescriptionverifiedbooleanIndicates whether GitHub considers the signature in this commit to be verified.reasonstringThe reason for verified value. Possible values and their meanings are enumerated in table below.signaturestringThe signature that was extracted from the commit.payloadstringThe value that was signed.verified_atstringThe date the signature was verified by GitHub.
These are the possible values for reason in the verification object:
ValueDescriptionexpired_keyThe key that made the signature is expired.not_signing_keyThe "signing" flag is not among the usage flags in the GPG key that made the signature.gpgverify_errorThere was an error communicating with the signature verification service.gpgverify_unavailableThe signature verification service is currently unavailable.unsignedThe object does not include a signature.unknown_signature_typeA non-PGP signature was found in the commit.no_userNo user was associated with the committer email address in the commit.unverified_emailThe committer email address in the commit was associated with a user, but the email address is not verified on their account.bad_emailThe committer email address in the commit is not included in the identities of the PGP key that made the signature.unknown_keyThe key that made the signature has not been registered with any user's account.malformed_signatureThere was an error parsing the signature.invalidThe signature could not be cryptographically verified using the key whose key-id was found in the signature.validNone of the above errors applied, so the signature is considered to be verified.
