You can create animated gifs by sending a POST request to /animated_gifs with a template uid (unique ID) and a list of template modifications you want to apply.
You can poll the GET request to the /animated_gifs/:uid endpoint for status updates and to retrieve the animated gif object referenced by it's uid. Animated gifs are usually rendered within a few seconds. When completed, the status changes to completed.
By using a webhook, you can be notified when the animated gif is rendered. Use the webhook_url parameter to tell Bannerbear where to POST the full Animated gif object, once the rendering is completed. The animated gif object will be posted to your webhook as JSON.
