Create attachment
Attach a file to an existing application. Supply the bytes inline as base64-encoded content, or point Greenhouse at a publicly fetchable url and we will download the file on your behalf — exactly one of the two is required. type controls how the attachment is classified in Greenhouse (resume, cover_letter, offer_letter, etc.); uploading a resume or cover_letter replaces any prior attachment of that type by reclassifying the existing one as other. Filenames are validated against the organization's blocklisted-extensions list (for example, .html is rejected for take_home_test).
