.. http:get:: /api/1/revision/(sha1_git)/
Get information about a revision in the archive.
Revisions are identified by **sha1** checksums, compatible with Git commit
identifiers.
See :func:`swh.model.git_objects.revision_git_object` in our data model
module for details about how they are computed.
:param string sha1_git: hexadecimal representation of the revision
**sha1_git** identifier
:reqheader Accept: the requested response content type,
either ``application/json`` (default) or ``application/yaml``
:resheader Content-Type: this depends on :http:header:`Accept` header
of request
:<json int n: sample input integer
:<json string s: sample input string
:<json array a: sample input array
:>json object author: information about the author of the revision
:>json object committer: information about the committer of the revision
:>json string committer_date: RFC3339 representation of the commit date
:>json string date: RFC3339 representation of the revision date
:>json string directory: the unique identifier that revision points to
:>json string directory_url: link to
:http:get:`/api/1/directory/(sha1_git)/[(path)/]` to get information
about the directory associated to the revision
:>json string id: the revision unique identifier
:>json boolean merge: whether or not the revision corresponds to a merge
commit
:>json string message: the message associated to the revision
:>json array parents: the parents of the revision, i.e. the previous
revisions that head directly to it, each entry of that array contains
an unique parent revision identifier but also a link to
:http:get:`/api/1/revision/(sha1_git)/` to get more information
about it
:>json string type: the type of the revision
:statuscode 200: no error
:statuscode 400: an invalid **sha1_git** value has been provided
:statuscode 404: requested revision can not be found in the archive
**Example:**
.. parsed-literal::
:swh_web_api:`revision/aafb16d69fd30ff58afdd69036a26047f3aebdc6/`
