Pass your dynamic field values in one request and get a finished image back in under 2 seconds. Once a template has [dynamic fields](/help/dynamic-fields), you can render it from code. One request in, one finished image out. No webhooks, no polling. ## [What you need](#what-you-need)What 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 template](#render-a-template)Render 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//export" \ -H "Authorization: Bearer " \ -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 bulk](#generate-in-bulk)Generate 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. ## [Language examples](#language-examples)Language examples Imejis has ready-to-copy quickstarts for cURL, Node.js, Python, Go, PHP, Ruby, and more. Browse them on the [API documentation](/apis) page, and see the full list of renderable pieces in the [component library](/components). ## [No code no problem](#no-code-no-problem)No code? No problem If you'd rather not write code, connect a template to [Zapier](/integrations/zapier), [Make](/integrations/make), or a [public link](/help/share-with-public-links) instead. ## [Frequently asked questions](#frequently-asked-questions)Frequently asked questions ### [How fast is a render](#how-fast-is-a-render)How fast is a render?

Ready-to-copy quickstarts cover cURL, Node.js, Python, Go, PHP, Ruby, and more on the [API documentation](/apis) page. ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://www.imejis.io/#organization","name":"Imejis.io","url":"https://www.imejis.io","logo":{"@type":"ImageObject","url":"https://www.imejis.io/icon-rounded.png","width":512,"height":512},"sameAs":["https://twitter.com/Imejis_io","https://www.instagram.com/imejis_io","https://in.pinterest.com/imejisio"],"contactPoint":{"@type":"ContactPoint","contactType":"customer support","url":"https://www.imejis.io/faqs"}},{"@type":"SoftwareApplication","@id":"https://www.imejis.io/#software","name":"Imejis.io","url":"https://www.imejis.io","applicationCategory":"DesignApplication","operatingSystem":"Web","description":"Template-based image generation API.
