Certificate PDF API & SDK

Need an SDK or API to create PDF certificates? Docweave is a certificate PDF API: pass a template + JSON (recipient, course, date) and get a print-ready certificate back in one REST call — or from an AI agent via the open-source MCP tool.

Issue one credential or thousands in parallel. Same per-document pricing whether the certificate is one page or a multi-page packet.

Generate a certificate PDF via the API

POST your template and data to /api/v1/pdf:

curl https://docweave.dev/api/v1/pdf \
  -H "Authorization: Bearer dw_live_your_key" \
  -H "Content-Type: application/json" \
  -H "Accept: application/pdf" \
  --output certificate.pdf \
  -d '{
    "source": {
      "type": "template",
      "template": "<h1>Certificate of Completion</h1><p>Awarded to {{ recipient }}</p><p>{{ course }} — {{ date }}</p>",
      "data": {
        "recipient": "Jordan Lee",
        "course": "Advanced TypeScript",
        "date": "2026-07-14"
      }
    },
    "options": { "format": "A4", "landscape": true },
    "idempotencyKey": "cert-jordan-lee-advanced-ts"
  }'

…or from an AI agent

Add the Docweave MCP server and your agent gets a generate_pdf tool — the same orchestration, no HTTP boilerplate:

// From an AI agent over MCP — no HTTP plumbing:
generate_pdf({
  source: {
    type: "template",
    template: "<h1>Certificate of Completion</h1><p>Awarded to {{ recipient }}</p><p>{{ course }} — {{ date }}</p>",
    data: { recipient: "Jordan Lee", course: "Advanced TypeScript", date: "2026-07-14" }
  },
  outputPath: "/tmp/certificate-jordan-lee.pdf"
})

Template example

Any HTML works as a template. Use {{ placeholders }} for the values you pass in data:

<article style="font-family: Georgia, serif; text-align:center; padding:64px;">
  <h1 style="letter-spacing:2px;">Certificate of Completion</h1>
  <p style="font-size:18px;">This certifies that</p>
  <h2 style="font-size:32px; margin:16px 0;">{{ recipient }}</h2>
  <p>has successfully completed</p>
  <h3>{{ course }}</h3>
  <p>Issued on {{ date }} by {{ issuer }}</p>
  <p style="margin-top:48px;">Credential ID: {{ credential_id }}</p>
</article>
