Introduction

Open Campus Achievements and Badges (OCAs and OCBs) are verifiable digital credentials that allow institutions, educators, and communities to recognize and reward learners in a trusted, portable way. Built on the Open Badges and W3C Verifiable Credentials standards, they provide a unified framework for issuing credentials that can be validated across platforms.

• Achievements (OCAs): Formal recognitions such as course completions, certifications, or licenses.

• Badges (OCBs): Lightweight, gamified recognitions that highlight participation, skills, or milestones.

Every credential issued through Open Campus is tied to a learner’s Open Campus ID (OCID) or wallet, ensuring that ownership is secure, verifiable, and interoperable across the Open Campus ecosystem.

With Open Campus Achievements/Badges, developers and issuers can:

• Recognize learning with portable, tamper-proof credentials.

• Engage communities through badges that encourage participation.

• Build trust by issuing credentials that follow global standards.

This guide will help you understand how to issue, integrate, and manage OCAs and OCBs using the Open Campus API.
