The Images API lets you upload, retrieve, and delete images associated with various resources — registrant photos, speaker headshots, sponsor logos, and other image fields.

​
What you can do

  • Upload images to any image field on a resource
  • Retrieve images by resource type, resource ID, and field ID
  • Delete images to remove them from a resource

​
Key concepts

Image addressing — Images are identified by three parameters: image_type (the resource type, e.g., “registrant” or “speaker”), image_id (the resource ID), and field_id (which image field on the resource). This allows multiple image fields per resource.
