DjangoDjango

Generate a unique OG image for every page, or any on-demand graphic, from a single Imejis template. The pattern below uses a Django view as a thin proxy: your API key stays on the server, and the browser (and social crawlers) only ever see your own URL.

Set two environment variables first: IMEJIS_API_KEY (from your dashboard) and IMEJIS_DESIGN_ID (any design's ID).

.env

IMEJIS_API_KEY=your_api_key
IMEJIS_DESIGN_ID=your_design_id

1 a view that renders the image1. A view that renders the image

This view takes a title query param, POSTs it to Imejis as a component.property override, and returns the finished image bytes. Because the key is sent server-side, it never reaches the client.

views.py

import os
 
import requests
from django.http import HttpResponse
 
 
def og_image(request):
    title = request.GET.get("title", "Untitled")
 
    response = requests.post(
        f"https://render.imejis.io/v1/{os.environ['IMEJIS_DESIGN_ID']}",
        headers={
            "dma-api-key": os.environ["IMEJIS_API_KEY"],
            "Content-Type": "application/json",
        },
        json={"headline.text": title},
    )
    response.raise_for_status()
 
    res = HttpResponse(response.content, content_type="image/jpeg")
    # Renders are deterministic, so cache aggressively at the edge/CDN.
    res["Cache-Control"] = "public, immutable, no-transform, max-age=31536000"
    return res

Wire it up with a route in urls.py.

urls.py

from django.urls import path
 
from . import views
 
urlpatterns = [
    path("og", views.og_image, name="og_image"),
]

2 point your metadata at it2. Point your metadata at it

Reference the view from your template's <head>, passing each page's real data. Social platforms fetch /og?title=… from your own domain, no key exposed.

templates/base.html

<meta
  property="og:image"
  content="https://your-site.com/og?title={{ post.title|urlencode }}"
/>

Override any field. Each dynamic component exposes keys like headline.text, title.color, or image.image. Send only the ones you want to change. A design's overridable fields are listed in its Share / API panel.
