HTTP from your stack

Native Zapier / Make / n8n apps are not shipped yet. Any tool that can POST JSON can render.

Use the same Render API from an HTTP step in Zapier, Make, Pipedream, n8n, Sheets, Airtable, or a CMS webhook.

Request

1. Create an API key under Integrations → API keys.
2. POST https://app.jsontoimg.com/api/v1/render?wait=60
3. Header Authorization: Bearer <your key>
4. JSON body:

{
  "template": "<design-id>",
  "format": "png",
  "layers": {
    "headline": { "text": "Welcome, Alex" }
  }
}

On success the body includes assetUrl when status is done.

When not to wait

For many rows, batch (max 50) or a webhook instead of ?wait=.

Worked example: n8n HTTP Request node. Full contract: API reference. Agents: MCP.
