API Usage

The Forgejo API for all versions that have the same major number (e.g. the major number of Forgejo 7.0.0 is 7) are compatible. There are breaking changes (e.g. removal of an API endpoint) when the major number changes and the release notes of this major version provide explanations to help developers upgrade their software accordingly. Read more about the Forgejo numbering scheme.

Enabling/configuring API access

By default, ENABLE_SWAGGER is true, and MAX_RESPONSE_ITEMS is set to 50.

Authentication

Forgejo supports these methods of API authentication:

HTTP basic authentication
token=... parameter in URL query string
access_token=... parameter in URL query string
Authorization: token ... header in HTTP headers

Generating and listing API tokens

A new token can be generated with a POST request to /users/:name/tokens.

Note that /users/:name/tokens is a special endpoint and requires you to authenticate using BasicAuth and a password, as follows:

$ curl -H "Content-Type: application/json" -d '{"name":"test","scopes":["write:package"]}' -u username:password https://forgejo.your.host/api/v1/users/<username>/tokens
{"id":1,"name":"test","sha1":"9fcb1158165773dd010fca5f0cf7174316c3e37d","token_last_eight":"16c3e37d","scopes":["write:package"]}

The keys of the JSON data object are name (the display name for the token) and scopes (list of Access Token scope names).

The sha1 (the token) is only returned once and is not stored in plain-text. It will not be displayed when listing tokens with a GET request; e.g.

$ curl --url https://yourusername:password@forgejo.your.host/api/v1/users/<username>/tokens
[{"name":"test","sha1":"","token_last_eight":"........"},{"name":"dev","sha1":"","token_last_eight":"........"}]

To use the API with basic authentication with two factor authentication enabled, you’ll need to send an additional header that contains the one-time password (6-digit rotating token). An example of the header is X-Forgejo-OTP: 123456 where 123456 is where you’d place the code from your authenticator. Here is how the request would look like in curl:

$ curl -H "X-Forgejo-OTP: 123456" --url https://yourusername:yourpassword@forgejo.your.host/api/v1/users/yourusername/tokens

You can also create an API key token via your Forgejo installation’s web interface: Settings | Applications | Generate New Token.

OAuth2 Provider

Access tokens obtained from Forgejo’s OAuth2 provider are accepted by these methods:

Authorization bearer ... header in HTTP headers
token=... parameter in URL query string
access_token=... parameter in URL query string

More on the `Authorization:` header

For historical reasons, Forgejo needs the word token included before the API key token in an authorization header, like this:

Authorization: token 65eaa9c8ef52460d22a93307fe0aee76289dc675

In a curl command, for instance, this would look like:

curl "http://localhost:4000/api/v1/repos/test1/test1/issues" \
    -H "accept: application/json" \
    -H "Authorization: token 65eaa9c8ef52460d22a93307fe0aee76289dc675" \
    -H "Content-Type: application/json" -d "{ \"body\": \"testing\", \"title\": \"test 20\"}" -i

As mentioned above, the token used is the same one you would use in the token= string in a GET request.

Pagination

The API supports pagination. The page and limit parameters are used to specify the page number and the number of items per page. As well, the Link header is returned with the next, previous, and last page links if there are more than one pages. The x-total-count is also returned to indicate the total number of items.

curl -v "http://localhost/api/v1/repos/search?limit=1"
...
< link: <http://localhost/api/v1/repos/search?limit=1&page=2>; rel="next",<http://localhost/api/v1/repos/search?limit=1&page=5252>; rel="last"
...
< x-total-count: 5252

The default and maximum values for the page parameter can be obtained from the https://forgejo.your.host/api/v1/settings/api endpoint.

$ curl https://codeberg.org/api/v1/settings/api
{
  "max_response_items": 50,
  "default_paging_num": 30,
  "default_git_trees_per_page": 1000,
  "default_max_blob_size": 10485760
}
