As answered by people managing HTTP Toolkit and Upload-Post.
Upload-Post's answer:
Upload-Post is the only API that lets you post to 10+ social platforms with a single endpoint. No need to integrate TikTok, Instagram, YouTube, and Facebook APIs separately — one call handles everything. We also offer true white-label: your users connect their accounts directly, so you never touch their credentials.
