export/urltask, then read the download links from the export task'sresult.files - Call

https://na1.fusion.foxit.com/oauth/tokenand cache the Bearer token.expires_inis about 24 hours and there is no refresh token - Upload first with
POST /pdf-services/api/documents/upload, start the operation, pollGET /pdf-services/api/tasks/{task-id}untilCOMPLETED, then downloadresultDocumentId - Read the body of a 429. It means either the rate limit (15 a minute in sandbox, 100 in production) or
QUOTA_EXCEEDEDwhen credits run out - Keep uploads under 100 MB, and delete documents with
