In case the organisation is managing the API, you will need certainly to manage the authorisation server.

Use application-level authorisation should you want to control which applications can access your API, but not which specific end users. This will be suitable if you want to use rate limiting, auditing, or billing functionality. Application-level authorisation is typically not suited to APIs holding personal or data that are sensitive you actually trust your consumers, as an example. another government department.

We recommend using OAuth 2.0, the open authorisation framework (specifically using the Client Credentials grant type). This service gives each registered application an OAuth2 Bearer Token, that can easily be used to make API requests in the application’s own behalf.

To produce authorisation that is user-level

Use user-level authorisation if you’d like to control which end users can access your API. This really is suitable for dealing with personal or data that are sensitive.

As an example, OAuth 2.0 is a authorisation that is popular in government, specifically with all the Authorisation Code grant type. Use OAuth 2.0 Scopes for more access control that is granular.

OpenID Connect (OIDC), which builds in addition to OAuth2, having its utilization of JSON Web Token (JWT), may be suitable in some instances, as an example a system that is federated.

For privacy and whitelisting

Use whitelisting if you need your API to be permanently or temporarily private, for instance to run a beta that is private. You can easily whitelist per application or per user.

You ought not to whitelist the IP addresses of this APIs you consume. This is because APIs can be provided using Content Delivery

Networks (CDNs) and load that is scalable, which count on flexible, rapid allocation of IP addresses and sharing. Rather than whitelisting, you should use an HTTPS egress proxy.

choose a suitable frequency that is refresh expiry period for your user access tokens – failure to refresh access tokens regularly can cause vulnerabilities
