Request an image upload URL
Request a presigned upload URL and a freshly generated key for the user’s signature or notary seal image. Each request produces a new key, so uploads never overwrite a previous image. Upload the image to the returned URL first, then save the profile via PUT /v1/users/ (passing the returned key as signatureKey / notarySealKey) to store the reference. Allowed for the user themselves or a caller with the manage permission.
Authorizations
Cognito-issued JWT access token. Send it as Authorization: Bearer <token>.
Path Parameters
The user's unique ID.
Body
Response
The presigned upload URL and key for the image.
The image type, either "signature" or "notary_seal".
A presigned upload (PUT) URL for the image.
The generated key the upload is stored under. Pass it as signatureKey / notarySealKey when saving the profile so the saved profile references this upload.
