The basics of API-driven video publishing
A concise walkthrough of how Upload24 handles authentication, upload ingestion, and status tracking when you automate video delivery.
Automation gets easier when the upload flow is predictable. In Upload24 the API is designed around one practical question: how do you move a file from your system into multiple connected social accounts without losing control over auth, scheduling, and delivery state?
The answer is to separate concerns clearly. You authenticate once, choose the upload method that fits your file size and infrastructure, then poll a status endpoint that tells you what happened for every linked account.
Access comes before transport
Upload24 uses bearer authentication to create and manage API keys, but the upload endpoints themselves also accept the raw API key through the X-Api-Key header. That split keeps key management inside the dashboard while letting automation run without a user session.
It also means the API is tenant-aware from the first request. A valid key resolves the tenant context, so every upload, status check, and retry stays scoped to the correct workspace.
Three upload flows cover different workloads
For smaller or straightforward integrations, multipart form upload is the shortest path: send metadata and the file in one request. If your backend already manages object transfer, use the presigned single-put flow. For large files or stricter resilience requirements, multipart presigning lets you upload in pieces and complete the session after you collect every ETag.
- Use /api/upload when you want the simplest request shape.
- Use /api/upload/presign-put when your server or worker uploads a single object directly to storage.
- Use /api/upload/multipart when large files or unstable networks make resumable transfer more important than brevity.
One upload request can fan out to several accounts
That is the part many teams underestimate. In Upload24, a single upload can target multiple linked accounts, and each destination has its own status, external id, and failure details. The public status payload keeps those account-level results visible instead of flattening them into a single success flag.
Operationally, this matters because quota is charged per target account, not per HTTP request. If you publish one asset to three channels, the platform treats that as three delivery actions.
Production usage is mostly about guardrails
The API enforces limits that are worth modeling in your client early: files must stay within the 2 GB cap, uploads must include at least one linked account, scheduled posts cannot be pushed beyond the allowed planning window, and YouTube-specific metadata becomes required as soon as you opt into YouTube fields.
That kind of validation is helpful because it moves integration errors closer to the caller. If you reflect the same checks in your own UI or job workers, you get fewer failed upload attempts and clearer retry behavior.
