# Compose many documents from one template

POST https://api.cloudraker.com/v1/spaces/{spaceId}/compose/batch
Content-Type: application/json

Renders the same template once per item — a run of invoices, contracts or letters from one call.

Every item's `data` is validated first. If ANY item fails, nothing renders and the call answers `422` with an `errors[]` naming the failing item indexes and instance paths: a half-finished batch is worse than none.

```json
{
  "template": "invoice",
  "items": [
    { "name": "acme-0042", "data": { "customer": "Acme", "total": 1240 } },
    { "name": "globex-0043", "data": { "customer": "Globex", "total": 990 } }
  ]
}
```

`output` decides what comes back:

* `files` (the default) stores each PDF and returns the list. An item's `name` names its file (`<name>.pdf`); without one the files are numbered from the template slug.
* `zip` stores ONE archive holding every PDF and returns that single file.

A `name` must be a bare file name — no `/`, no `\`, no `..`, no leading dot — and two items may not end up with the same file name.
