API ACCESS FOR WEB VIEWS

API access can also be turned on for each web view in |RCE| that is decorated with a @LoginRequired decorator. To enable API access, change the standard login decorator to @LoginRequired(api_access=True).

From |RCE| version 1.7.0 you can configure a white list of views that have API access enabled by default. To enable these, edit the |RCE| configuration .ini file. The default location is:

• |RCE| Pre-2.2.7 :file:`root/rhodecode/data/production.ini`
• |RCE| 3.0 :file:`config/_shared/rhodecode.ini`

To configure the white list, edit this section of the file. In this configuration example, API access is granted to the patch/diff raw file and archive.

## List of controllers (using glob syntax) that AUTH TOKENS could be used for access.
## Adding ?auth_token = <token> to the url authenticates this request as if it
## came from the the logged in user who own this authentication token.
##
## Syntax is <ControllerClass>:<function_pattern>.
## The list should be "," separated and on a single line.
##
api_access_controllers_whitelist = RepoCommitsView:repo_commit_raw,RepoCommitsView:repo_commit_patch,RepoCommitsView:repo_commit_download

After this change, a |RCE| view can be accessed without login by adding a GET parameter ?auth_token=<auth_token> to a url. For example to access the raw diff.

http://<server>/<repo>/changeset-diff/<sha>?auth_token=<auth_token>

By default this is only enabled on RSS/ATOM feed views. Exposing raw diffs is a good way to integrate with 3rd party services like code review, or build farms that could download archives.

API ACCESS

All clients are required to send JSON-RPC spec JSON data.

{
    "id:"<id>",
    "auth_token":"<auth_token>",
    "method":"<method_name>",
    "args":{"<arg_key>":"<arg_val>"}
}

Example call for auto pulling from remote repositories using curl:

curl https://server.com/_admin/api -X POST -H 'content-type:text/plain' --data-binary '{"id":1,
"auth_token":"xe7cdb2v278e4evbdf5vs04v832v0efvcbcve4a3","method":"pull", "args":{"repoid":"CPython"}}'

Provide those parameters:

• id A value of any type, which is used to match the response with the request that it is replying to.
• auth_token for access and permission validation.
• method is name of method to call
• args is an key:value list of arguments to pass to method

The |RCE| API will always return a JSON-RPC response:

{
    "id": <id>, # matching id sent by request
    "result": "<result>"|null, # JSON formatted result, null if any errors
    "error": "null"|<error_message> # JSON formatted error (if any)
}

All responses from API will be with HTTP/1.0 200 OK status code. If there is an error when calling the API, the error key will contain a failure description and the result will be null.

API CLIENT

To install the |RCE| API, see :ref:`install-tools`. To configure the API per instance, see the :ref:`rc-tools` section as you need to configure a :file:`~/.rhoderc` file with your |authtokens|.

Once you have set up your instance API access, use the following examples to get started.

# Getting the 'rhodecode' repository
# from a RhodeCode Enterprise instance
rhodecode-api --instance-name=enterprise-1 get_repo repoid:rhodecode

Calling method get_repo => http://127.0.0.1:5000
Server response
{
    <json data>
}

# Creating a new mercurial repository called 'brand-new'
# with a description 'Repo-description'
rhodecode-api --instance-name=enterprise-1 create_repo repo_name:brand-new repo_type:hg description:Repo-description
{
  "error": null,
  "id": 1110,
  "result": {
    "msg": "Created new repository `brand-new`",
    "success": true,
    "task": null
  }
}

A broken example, what not to do.

# A call missing the required arguments
# and not specifying the instance
rhodecode-api get_repo

Calling method get_repo => http://127.0.0.1:5000
Server response
"Missing non optional `repoid` arg in JSON DATA"

You can specify pure JSON using the --format parameter.

rhodecode-api --format=json get_repo repoid:rhodecode

In such case only output that this function shows is pure JSON, we can use that and pipe output to some json formatter.

If output is in pure JSON format, you can pipe output to a JSON formatter.

rhodecode-api --instance-name=enterprise-1 --format=json get_repo repoid:rhodecode | python -m json.tool

API METHODS

Each method by default required following arguments.

id :      "<id_for_response>"
auth_token : "<auth_token>"
method :  "<method name>"
args :    {}

Use each param from docs and put it in args, Optional parameters are not required in args.

args: {"repoid": "rhodecode"}
