Account Account Info APIs

Files

The HubSpot Files API uploads and manages files in the HubSpot file manager — the storage layer behind email images, CMS pages, knowledge base attachments, and CRM record uploads. It supports direct multipart uploads, asynchronous import-from-URL for large external files, folder organisation, and signed-URL generation for private file access. Files can be checked for duplicates by stat path, retrieved by id, GDPR-deleted, and listed by folder, giving agents full control over the asset library that other HubSpot APIs reference by file id.
