}Upload campaign media
Uploads an image to attach to a campaign message. Send multipart/form-data with a single file field: PNG, JPEG, WebP, or GIF (animation is preserved), up to 4 MB and 4096×4096 pixels. File contents are verified — SVG and files whose bytes don’t match their declared type are rejected. Returns an absolute HTTP(S) URL on the server’s configured public origin; reference it as media.url when creating or editing a campaign. The image never changes the message’s presentation — set message.presentation for that. Objects are immutable and retained; upload a new file to change an image.
