In this chapter, you will find general policies and conventions, which you must take into account when you create an API.
In this chapter, you will find general policies and conventions, which you must take into account when you create an API.
In this section, you will find information about handling queries that are sent to the API Server.
When a query is sent to the API Server, there is a test to ascertain the success of the primary and, possibly, secondary login in the session for the current project (see Authentication).
NOTE: This test is not done if the API method used by the query is marked as AllowUnauthenticated.
The imx-session-<API project name> cookie is evaluated to allocate the current session.
If a cookie is passed that cannot be associated with an active session in the current process, the security token in the cookie is used to set up a new session (see Session status and security tokens).
If there is no primary login, the API Server tries to establish a database connection through one of the enabled single sign-on authentication modules.
If login cannot be carried out, the process is canceled and the HTTP error code 500 is passed to the client (see Response codes).
The API Server checks whether the currently logged in user is authorized to run the method. If the user does not have the required permissions, the process is canceled and the HTTP error code 500 is passed to the client (see Response codes).
The API Server calls the validators stored with the API method one by one. If one fails, the process is canceled and the HTTP error code 400 is passed to the client (see Response codes).
Determines the WHERE clause with internal and external filters
Loads data from the database
Augments an entity with calculated columns
An entity in delayed-logic mode can be changed with a POST query or deleted with a DELETE query. An entity in this mode is stateless and does not take up any resources on the server after it has been processed.
Supported HTTP methods:
GET (reads an entity)
POST (changes an entity)
DELETE (deletes an entity)
An interactive entity must be created once with a PUT query and after that they obtain their own ID. Use the ID in subsequent queries (POST or DELETE).
Supported HTTP methods:
GET (loads an entity)
PUT (creates an interactive entity)
POST (changes an interactive entity)
DELETE (deletes an interactive entity)
User authentication is carried out on the API Server for each API project.
Running an API method requires prior authentication on an API project. If the API method is marked as AllowUnauthenticated, authentication is not required (you can find an example in the SDK)
Authentication has two steps:
Required primary authentication: Default authentication through an authentication module
Optional secondary authentication: Multi-factor authentication (using OneLogin)
For more information about configuring authentication, see the One Identity Manager Web Application Configuration Guide.
You can specify how users authenticate themselves on your API. You configure authentication in the API project.
To configure authentication
Edit your API project.
Create the SessionAuthDbConfig class and populate the following properties:
Product: Specify the application with the authentication module that you want to use (for example the WebDesigner or the Manager),
SsoAuthentifiers: Specify the single sign-on authentication modules to use.
ExcludedAuthentifiers: Specify the authentication modules not to use.
