## Glossary

Endpoint
:   Resource available though the api.
    The endpoint is the URL where your api can be accessed by a client application

Method
:   HTTP verbs to indicate the desired action to be performed on the identified resource.
    See: https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods

itemtype
:   A GLPI type, could be an asset, an itil or a configuration object, etc.
    This type must be a class who inherits CommonDTBM GLPI class.
    See [List itemtypes](https://forge.glpi-project.org/projects/glpi/embedded/class-CommonDBTM.html).

searchOption
:   A column identifier (integer) of an itemtype (ex: 1 -> id, 2 -> name, ...).
    See [List searchOptions](#list-searchoptions) endpoint.

JSON Payload
:   content of HTTP Request in json format (HTTP body)

Query string
:   URL parameters

User token
:   Used in login process instead of login/password couple.
    It represent the user with a string.
    You can find user token in the settings tabs of users.

Session token
:   A string describing a valid session in glpi.
    Except initSession endpoint who provide this token, all others require this string to be used.

App(lication) token
:   An optional way to filter the access to the api.
    On api call, it will try to find an api client matching your ip and the app toekn (if provided).
    You can define an api client with an app token in general configuration for each of your external applications to identify them (each api client have its own history).

## Important

* you should always precise a Content-Type header in your HTTP calls.
   Currently, the api supports:
  * application/json
  * multipart/form-data (for files upload, see [Add item(s)](#add-item-s) endpoint.

* GET requests must have an empty body. You must pass all parameters in URL.
  Failing to do so will trigger an HTTP 400 response.

* By default, sessions used in this API are read-only.
  Only Some methods have write access to session:
  * [initSession](#init-session)
  * [killSession](#kill-session)
  * [changeActiveEntities](#change-active-entities)
  * [changeActiveProfile](#change-active-profile)

  You could pass an additional parameter "session_write=true" to bypass this default.
  This read-only mode allow to use this API with parallel calls.
  In write mode, sessions are locked and your client must wait the end of a call before the next one can execute.

* You can filter API access by enable the following parameters in GLPI General Configuration (API tab):
  * IPv4 range
  * IPv6 address
  * *App-Token* parameter: if not empty, you should pass this parameter in all of your api calls

* Session and App tokens could be provided in query string instead of header parameters.

## Init session

* **Description**: Request a session token to uses other api endpoints.
* **Method**: GET
* **Parameters**: (Headers)

     You should pass this 2 parameters in [http basic auth](https://en.wikipedia.org/wiki/Basic_access_authentication).
     It consists in a Base64 string with login and password separated by ":"
     A valid Authorization header is:
        * "Authorization: Basic base64({login}:{password})"

    > **OR**

  * an *user_token* defined in User Preference (See 'Remote access key')
     You should pass this parameter in 'Authorization' HTTP header.
     A valid Authorization header is:
        * "Authorization: user_token q56hqkniwot8wntb3z1qarka5atf365taaa2uyjrn"

   So, we provide arrays to guarantying sorted rows.

  * ¹ - *contains* will use a wildcard search per default. You can restrict at the beginning using the *^* character, and/or at the end using the *$* character.
  * ² - *equals* and *notequals* are designed to be used with dropdowns. Do not expect those operators to search for a strictly equal value (see ¹ above).

### ERROR_RANGE_EXCEED_TOTAL

The range parameter you provided is superior to the total count of available data.

### ERROR_GLPI_ADD

## Servers configuration

By default, you can use <http://path/to/glpi/apirest.php> without any additional configuration.

You'll find below some examples to configure your web server to redirect your <http://.../glpi/api/> url to the apirest.php file.

### Apache Httpd

We provide in root .htaccess of GLPI an example to enable api url rewriting.

You need to uncomment (removing #) theses lines:

```apache
#<IfModule mod_rewrite.c>
#   RewriteEngine On
#   RewriteCond %{REQUEST_FILENAME} !-f
#   RewriteCond %{REQUEST_FILENAME} !-d
#   RewriteRule api/(.*)$ apirest.php/$1
#</IfModule>
```

By enabling url rewriting, you could use api with this url : <http://path/to/glpi/api/>.
You need also to enable rewrite module in apache httpd and permit GLPI's .htaccess to override server configuration (see AllowOverride directive).

### Nginx

This example of configuration was achieved on ubuntu with php7 fpm.

```nginx
server {
   listen 80 default_server;
   listen [::]:80 default_server;

   # change here to match your GLPI directory
   root /var/www/html/glpi/;

   index index.html index.htm index.nginx-debian.html index.php;

   server_name localhost;

   location / {
      try_files $uri $uri/ =404;
      autoindex on;
   }

   location /api {
      rewrite ^/api/(.*)$ /apirest.php/$1 last;
   }

   location ~ [^/]\.php(/|$) {
      fastcgi_pass unix:/run/php/php7.0-fpm.sock;

      # regex to split $uri to $fastcgi_script_name and $fastcgi_path
      fastcgi_split_path_info ^(.+\.php)(/.+)$;

      # Check that the PHP script exists before passing it
      try_files $fastcgi_script_name =404;

      # Bypass the fact that try_files resets $fastcgi_path_info
      # # see: http://trac.nginx.org/nginx/ticket/321
      set $path_info $fastcgi_path_info;
      fastcgi_param  PATH_INFO $path_info;

      fastcgi_param  PATH_TRANSLATED    $document_root$fastcgi_script_name;
      fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

      include fastcgi_params;

      # allow directory index
      fastcgi_index index.php;
   }
}

```
