# Fill a Word template (`documents_fill_template`)

Makes a new Word file from a .docx template, its placeholders filled from data.

A new Word file from a .docx template in the store, its {{ placeholders }} filled from data. Templates use Jinja: {{ name }}, {% if paid %}...{% endif %}, and {%tr for row in rows %} to repeat a table row. Turn the result into a PDF with documents_convert_to_pdf.

Price: $0.02 a call. A call that fails costs nothing.

## Use it when

The same document is made again and again with different details: delivery notes, contracts.

## Say this to your agent

> Fill in the delivery note template for Café Lotte's espresso machine, delivered on Friday.

## Errors

| Code | Status | When | Fix |
|---|---|---|---|
| `not_found` | 404 | No file in the store has that file_id. | Find it with files_list, or upload it first. |
| `unsupported_type` | 400 | The file is not a Word .docx file. | Use a .docx template. |
| `template_error` | 422 | The template could not be filled; the message says where. | Fix the template or give the data it asks for. |
| `template_too_slow` | 422 | Filling took too long. | Simplify the template's loops. |
| `storage_full` | 409 | The file store has no room for the new file. | Delete files with files_delete, or add room with files_add_storage. |
| `too_large` | 413 | The result would be over 25 MB. | Make it smaller, or split it. |
