Generate an image from a template with a single POST request, using HttpClient. Imejis returns the finished image directly, so there are no webhooks and nothing to poll.

Set two environment variables first: IMEJIS_API_KEY (from your dashboard) and IMEJIS_DESIGN_ID (any design's ID). Then send the fields you want to change as component.property pairs, for example headline.text.

using System.Text;
 
var designId = Environment.GetEnvironmentVariable("IMEJIS_DESIGN_ID");
var apiKey = Environment.GetEnvironmentVariable("IMEJIS_API_KEY");
var json = "{\"headline.text\":\"Hello from C#\"}";
 
using var client = new HttpClient();
client.DefaultRequestHeaders.Add("dma-api-key", apiKey);
 
var content = new StringContent(json, Encoding.UTF8, "application/json");
var response = await client.PostAsync($"https://render.imejis.io/v1/{designId}", content);
var bytes = await response.Content.ReadAsByteArrayAsync();
 
await File.WriteAllBytesAsync("output.jpg", bytes);
Console.WriteLine($"status {(int)response.StatusCode} bytes {bytes.Length}");

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

The response is the raw image (image/jpeg by default). Save it to disk, stream it, or return it straight from your own endpoint.
