Manually scheduling posts one at a time works fine at small volume. It stops working once you're dealing with dozens or hundreds of posts — a content backlog from another tool, a client's entire back catalog, or a batch of AI-generated posts that all need to go out on a schedule. That's where doing it programmatically through an API actually pays off.

## Why bulk scheduling through the API beats the dashboard for volume

OneUp's dashboard already supports bulk upload via CSV, Google Drive, or Dropbox — a solid option if your content already lives in one of those formats. But once you're generating content programmatically (pulling from a database, transforming data from another system, or building scheduling into a larger automated pipeline) working directly against the API removes the extra step of exporting to CSV first.

## The basic shape of a bulk scheduling script

A programmatic bulk scheduling workflow generally follows this pattern:

1. **Gather your content** — from wherever it lives: a database, a spreadsheet you're reading programmatically, another API, or AI-generated output.
2. **Loop through each item**, formatting it into the structure OneUp's API expects for a post (account, caption, media, scheduled time).
3. **Set staggered scheduled times** for each post rather than firing them all at the same timestamp — spacing content out, whether by a fixed interval or some other logic, is worth building into the script itself rather than handling manually afterward.
4. **Make the authenticated request** for each post, using your OneUp API key.
5. **Handle errors individually** — a bulk job with 200 posts will likely have at least one that fails for a platform-specific reason (an oversized image, a missing required field), so build in logging or retry logic rather than assuming every request succeeds.

## Where to find the exact request format

The specific endpoint, required fields, and authentication details are documented at docs.oneupapp.io — the structure above is the general shape of a bulk scheduling script, not literal code to copy and run, since field names and requirements should come from the actual API reference rather than a generic outline.

## When this is worth building versus using the dashboard's bulk upload

If your content already exists as a clean CSV or lives in Google Drive or Dropbox, the dashboard's built-in bulk upload is simpler. Scripting against the API directly makes more sense once your content is generated or transformed programmatically as part of a larger workflow, rather than sitting in a file ready to import.
