A plain REST API

One POST with a design and a format. No SDK required on the calling side, no long-lived connection, no proprietary client.

render.sh

# 1. Create the job
curl -X POST 'https://api.polotno.com/api/renders?KEY=YOUR_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
    "design": { "width": 1080, "height": 1080, "pages": [ ... ] },
    "format": "pdf",
    "vector": true
  }'
# -> { "id": "fp1f2rtva", "status": "scheduled", "output": null, ... }

# 2. Poll for the result (or pass a webhook instead)
curl 'https://api.polotno.com/api/renders/fp1f2rtva?KEY=YOUR_API_KEY'

One endpoint, every format

Switch the format field to get png, jpeg, pdf, gif, or mp4 from the same design. Nothing else about the request changes.

Jobs, not blocking calls

POST schedules a render and returns a job id immediately. Poll the job, or pass a webhook URL and receive the full payload when it completes.

The design is just JSON

Send store.toJSON() from the editor, a template stored in your database, or a payload assembled from a data row on your backend. The API does not care which.

Print options where you need them

vector: true gives selectable text; add pdfx: 'x-4' and color.space: 'CMYK' for a print-ready deliverable.
