Posting PDFs / document carousels

LinkedIn is the only provider Postiz supports PDF posting on, and only through document-carousel posts. When you create a carousel of images on a LinkedIn Page, Postiz combines the images into a PDF document and uploads it as a LinkedIn document share. You don’t upload a PDF directly — Postiz produces the PDF from your images. This is not supported on other platforms; the public-API upload endpoint does not accept application/pdf.
