REST API endpoints for Git tags
Use the REST API to interact with tag objects in your Git database on GitHub Enterprise Server.
About Git tags
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 Enterprise Server. The API only supports annotated tag objects, not lightweight tags.
Create a tag object
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:
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. |
