Generate images with the API

Once a template has dynamic fields, you can render it from code. One request in, one finished image out. No webhooks, no polling.

What you needWhat you need

• An API key from your Imejis dashboard.
• The design ID of the template you want to render.
• Values for the template's dynamic fields.

Render a templateRender a template

Send the field values to the render endpoint for your design and you get the image back in the response. In pseudocode:

curl -X POST "https://api.imejis.io/designs/<DESIGN_ID>/export" \
  -H "Authorization: Bearer <API_KEY>" \
  -H "Content-Type: application/json" \
  -d '{ "title": "Welcome, Alex", "avatar": "https://example.com/alex.png" }' \
  --output result.png

Each key in the body matches a dynamic field name from your template. Anything you don't override keeps its designed default.

Generate in bulkGenerate in bulk

To produce many images, one per customer, per row, or per event, loop over your data and call the endpoint once per record. The template stays the same. Only the field values change.
