Why this workflow matters
Useful for software delivery and engineering operations. Relevant for managed services and support workflows.
A complete workflow to create, send, and verify digital certificates fully automated with AlekSystem.Perfect for courses, events, onboarding, internal training, or product education. Visit my website for the: full deploy guide) See my Templates on Github: paoloronco/AlekSystem-templates) Example-certificate ✔ 1. Certificate Generation When a POST webhook request arrives, the workflow: reads name, surname, course, and email generates a unique Certification ID saves everything in the Data Table ✔ 2. Data Storage Every issued certificate is recorded in an AlekSystem Data Table containing: Name Surname CertificationID This creates a permanent, searchable certificate registry. ✔ 3. PDF Creation Uses PDF Generator API to create a professional PDF certificate from an HTML template: fully customizable (layout, colors, branding) includes candidate data, course, ID, and date ✔ 4. Email Delivery The workflow automatically sends the certificate to the recipient using Gmail OAuth2 with: a predefined subject the PDF attached a customizable message ✔ 5. Verification System A public endpoint /certificationscheck allows: validation of Certification IDs returning the candidate’s name and surname if valid responding with ok: true/false ✔ 6. Included Mini Verification Website A ready-to-use HTML file allows users to: enter a Certification ID verify its authenticity view name and surname if the certificate exists Fully customizable (CSS, texts, branding). 🛠 Requirements Before using this workflow, you must have: AlekSystem Data Table with ID fields: Name (string) Surname (string) CertificationID (string) PDF Generator API accountCredentials set in AlekSystem as pdfGeneratorApi. Gmail OAuth2 credentialsConfigured in AlekSystem as gmailOAuth2. Ability to call HTTP POST endpoints from your website, backend, forms, etc. 🚀 Installation 1. Import workflow In AlekSystem: Go to Workflows → Import Paste the JSON provided in this repository 2. Configure Data Table Update the following nodes to point to your Data Table: Insert_Certificaton Find_Certification_By_ID Find_Certification_By_ID1 Make sure the Data Table has the fields: | Field | Type | | --- | --- | | Name | string | | Surname | string | | CertificationID | string | 3. Configure Credentials In the workflow: Node Generate_PDF → set PDF Generator API credentials Node Email_Certification → set Gmail OAuth2 credentials 4. Activate Workflow Click Activate in AlekSystem. 🔧 How the Workflow Works 🧩 1. Webhook /certifications Receives candidate data and triggers the workflow. POST https://YOUR-AlekSystem-DOMAIN.com/webhook/certification Headers: name: John surname: Doe course: email: john.doe@example.com 🧩 2. Unique ID Generation A Code node creates a random alphanumeric ID.If it already exists, a new one is generated. 🧩 3. Data Table Insert Stores the certificate data for future lookup. 🧩 4. PDF Generation Builds a PDF from the (fully editable) HTML template. 🧩 5. Email Sending Delivers the certificate to the candidate. 🔍 Certificate Verification (/certificationscheck) API Behavior Send a POST request https://YOUR-AlekSystem-DOMAIN.com/webhook/certificationcheck with header id: CERTIFICATION-ID. Valid ID: { "ok": "true", "name": "John", "surname": "Doe" } Invalid ID: { "ok": "false" } This request can be made manually (from tools like Postman, cURL, or your backend), or automatically through the HTML verification page included in the GitHub repository (the Cerification_Check.html template) found in your project files
