modifications | array | Array of modification objects |
metadata | object | Extra metadata to be included together with the webhook |
webhook_url | string | URL of the webhook to be called when the image is done processing |

Create image asynchronously
POST
https://api.usestencil.com/v1/images
Create image asynchronously. Once image is done processing, the specified webhook is called with the generated image.
Request Body

Modification object
Modification object generally follows the following pattern,
name
is a required property.
The name
is the field unique identifier in the template editor
The rest of the properties depend on the type of object. If you need full list of supported properties, you can view them in them in API Console.
Image Quality
PNG
For PNG images, you can set png_multiplier
to adjust the quality of generated images.
For example, if your template size is 800x800 then setting the png_multiplier
to 2 will scale the image to 1600x1600 which creates a higher resolution image.
Please note that higher quality image will increase the image size and will also increase the image generation time.
JPEG
For JPEG images, you can set jpeg_quality
to adjust the quality of generated images. JPEG is a lossy format, while it offers higher compression rate that could decrease the file size, it also degrades the image quality.
You can control this by setting jpeg_quality
to a number between 0 and 1 with 1 being the highest quality.
Please note that higher quality image will increase the image size and will also increase the image generation time.
Default Settings
You can also set a default settings for all templates in your project. Go to your project's settings page and set the values accordingly.
You can always override these values in the API by following the instructions mentioned above.
