Verifycate for WordPress

Issue verifiable certificates from your WordPress LMS. The plugin connects LearnDash, Tutor LMS, LearnPress, LifterLMS, Sensei and any custom completion hook to Verifycate, so a certificate is queued and issued automatically when a learner completes a course.

This repository is the open-source client. The Verifycate service itself is a hosted, paid product; the plugin is a thin client that talks to its public API through the Verifycate PHP SDK.

Status

0.1.0. Available from GitHub Releases; the WordPress.org listing is pending.

Requirements

  • WordPress 6.2+
  • PHP 7.4+
  • An active Verifycate workspace with API access
  • A workspace API key with certificates:read and certificates:write

What it does

  • Connection — paste a workspace API key, and the plugin resolves the workspace, checks the key scopes and plan, and tests the connection. API and portal URLs plus an optional workspace override live under advanced settings.
  • Mappings — map one course, an entire LMS catalogue, or a custom hook to a certificate. Specific-course mappings take precedence over “any course”.
  • Attributes — map learner and course data to certificate attributes with tokens such as {user_name}, {course_title}, {completion_date}, {user_meta:key} and {course_meta:key}.
  • Durable queue — completions are written to a database queue and processed by WP-Cron with exponential backoff. Failed jobs are visible and retryable.
  • Repeat completions — issue once per learner, or reissue the certificate onto the latest published design for recertification.
  • Wallet — [verifycate_wallet] shortcode and a server-rendered “Verifycate Wallet” block so logged-in learners can open their certificates.
  • WP-CLI — connection status, mappings, direct issuance, queue processing, retries and logs.

Certificate design happens in the Verifycate dashboard. The plugin handles the connection, mapping and issuance.

Installation

Release zip

Download the latest plugin zip from GitHub Releases, or build it locally with composer build.

  1. Upload the plugin zip to /wp-content/plugins/verifycate/, or install it through the WordPress plugins screen.
  2. Activate the plugin.
  3. Go to Verifycate → Get started, paste a workspace API key, and click Connect Verifycate. The plugin finds the workspace, checks the key’s scopes and plan, and tests the connection.
  4. Create at least one certificate in the Verifycate dashboard.
  5. Go to Verifycate → Mappings and map a course to that certificate.

The release zip includes the PHP SDK in vendor/; no Composer run is needed on the site.

Development

The plugin uses the public verifycate/php-sdk package through a Composer VCS repository. Composer fetches the SDK automatically; no credentials are needed. Keep both checkouts side by side if you are working on the SDK too:

mkdir -p ~/projects/verifycate-os
cd ~/projects/verifycate-os

git clone https://github.com/verifycate/wp-plugin.git
git clone https://github.com/verifycate/php-sdk.git

cd wp-plugin
composer install          # PHP dependencies, SDK included
npm install               # JS tooling and @wordpress/env

npm run env:start         # local WordPress at http://localhost:8888

The default wp-env admin credentials are admin / password.

Quality checks

composer lint             # PHPCS with WordPress + PHPCompatibility standards
composer analyse          # PHPStan level 6
composer test             # PHPUnit unit tests (Brain Monkey)
composer check            # all of the above
composer build            # distributable zip in build/verifycate.zip
npm run plugin-zip        # JS-side zip helper

CI runs the same checks on PHP 7.4–8.3, the official Plugin Check against the built plugin, and uploads the zip as an artifact on every push and pull request.

Pushing a v* tag runs .github/workflows/release.yml, rebuilds the zip from that tag, and publishes it as a GitHub Release. You can also start that workflow manually with an existing tag.

CI and the PHP SDK

The PHP SDK is public at verifycate/php-sdk. Composer resolves it through the VCS repository in composer.json; CI and release builds need no credentials.

Supported LMS hooks

Each adapter normalizes the LMS event into the shared issuance pipeline and never calls the API directly.

LMS Hook Arguments used
LearnDash learndash_course_completed $data['user'], $data['course'], optional $data['progress']['score']
Tutor LMS tutor_course_complete_after $course_id, $user_id
LearnPress learn-press/user-course-finished $course_id, $user_id, $result
LifterLMS lifterlms_course_completed $student_id, $course_id
Sensei sensei_user_course_end $user_id, $course_id
Custom verifycate_course_completed $user_id, $course_id, $event, $context

Custom hook

Use the custom hook for membership, e-commerce or in-house course plugins:

do_action( 'verifycate_course_completed', $user_id, $course_id );

do_action(
    'verifycate_course_completed',
    $user_id,
    $course_id,
    'course_completed',
    array(
        'course_title' => 'Advanced Leadership',
        'score'        => 92,
        'cohort'       => 'Spring 2026',
    )
);

Create a mapping with Custom hook, enter the event name (default course_completed) and leave the course id at 0 to match any course. The $context array is available to attribute templates as {context:key}.

Mapping behaviour

  • Any course — one certificate covers every published course in that LMS.
  • Specific course — overrides an any-course mapping for the same certificate.
  • Skip duplicates — a learner receives the certificate once. Pending jobs also suppress a second queue entry.
  • Issue again — reissues the existing certificate onto the latest published design (recertification).
  • Auto-issue — import the recipient and release the credential immediately. Turn it off to queue recipients and release them from the dashboard.
  • Attributes — one key = template per line. Only keys declared on the certificate are sent. Unknown tokens are left as-is so typos are visible.

If the certificate is still a draft, recipients queue but cannot be released. Publishing the certificate in Verifycate is the single action that releases the queue.

Wallet

Shortcode:

[verifycate_wallet title="My certificates" empty_text="Nothing here yet." limit="20"]

Block: insert Verifycate Wallet from the widget category. It is rendered on the server, so no block build step is needed.

The wallet calls the API with the logged-in learner's email and caches the result for five minutes. It only shows issues whose certificate is active.

WP-CLI

wp verifycate status
wp verifycate mappings
wp verifycate issue <certificate-id> --email=ada@example.com --name="Ada Lovelace"
wp verifycate issue <certificate-id> --email=ada@example.com --attributes='{"course_hours":"40"}'
wp verifycate process --limit=20
wp verifycate retry
wp verifycate logs --level=error --limit=20

Data and privacy

The plugin stores:

  • the workspace slug, encrypted API key and API/portal URLs in wp_options (verifycate_settings);
  • course-to-certificate mappings in {prefix}verifycate_mappings;
  • queued issuance jobs and retry state in {prefix}verifycate_jobs;
  • bounded activity logs in {prefix}verifycate_logs (30-day retention).

The API key is encrypted at rest with sodium secretbox when available, falling back to OpenSSL AES-256-GCM. The key is never rendered in full.

Completions send the learner's name, email address, course title, completion date, score when available, and mapped certificate attributes to the Verifycate API. Nothing is sent before the site is connected and a mapping is saved.

Uninstall removes settings, tables, queue history and logs only when the administrator enabled “Delete … when the plugin is uninstalled” on the Get started screen. The default is to keep data so a reinstall resumes cleanly.
