AttachmentService · AttachmentService_CreateAttachment
Access
Requires an authenticated, active account. Instance policy and the operation-specific checks below still apply.
Upload bytes in JSON
Send Attachment directly, with filename, MIME type and base64 content. The optional memo field is a full memo resource name and requires permission to manage that memo. The default upload size limit is 32 MiB unless storage settings change it. Creation returns metadata; content is input-only. The immediate response may omit the memo backlink even when linkage succeeded, so GetAttachment can be used to read the final projection.
Request
CreateAttachment creates a new attachment.
