In this post, I will show you how to access DHIS2 data using OAuth2. Let’s start:

DHIS2 supports the OAuth2 authentication protocol. OAuth2 is an open standard for authorization which it allows third-party clients to connect on behalf of a DHIS2 user and get a reusable bearer token for subsequent requests to the Web API. DHIS 2 does not support fine-grained OAuth2 roles but rather provides applications access based on user roles of the DHIS2 user.

Each client for which you want to allow OAuth 2 authentication must be registered in DHIS2.
