Configuring certificates

Overview

This document will help an implementer configure a certificate (template and QR code) for a health event such as vaccination. This section includes configuring:

• Generating signed key pairs

• Certificate generation request

• QR code section

• Certificate template

API

The DIVOC platform provides API services for generating digitally verifiable QR code-based vaccination certificates. The API for certificate generation has 6 sections:

1. PreEnrollmentCode: This section is linked to the 'dose' in the vaccination section to uniquely identify an event. For example, beneficiary registration number (R101) and dose number (1) as (R101-1) will be used to identify the first dose event uniquely. Similarly, beneficiary registration number (R101) and dose number (2) as (R101-2) will be used to identify the second dose event uniquely.

2. Recipient: It contains information about the beneficiary.

3. Vaccination: It contains details about the vaccination event such as name, batch, and vaccination date.

4. Vaccinator: It contains details about the vaccinator.

5. Facility: It contains details about the facility where beneficiaries will get vaccinated.

6. Meta: It contains additional information, which is not part of the QR code, such as the number of past doses taken.

Sample for default certificate generation request

• You can refer to the API service call with sample data below:
