Teilt PDF per Barcode API
Was dieser Endpunkt bewirkt: Der PDF4me Teilt PDF per Barcode REST API Scans a PDF Ein Dokument wird nach Seiten mit einem bestimmten Barcode-Wert durchsucht und bei jeder übereinstimmenden Seite geteilt. Definieren Sie ein Barcode-Zeichenkette, Filtermethode und Barcode-TypDann entscheiden Sie, ob Sie kürzen möchten. vorher, nachher oder durch Entfernen die Barcode-Seite. API verwendet konfigurierbar DPI Die Technologie ermöglicht eine zuverlässige Barcode-Erkennung unabhängig von der Druckqualität und kann optional aufeinanderfolgende Seiten mit demselben Barcode in einem einzigen Ausgabebereich zusammenfassen. Sie eignet sich ideal für die automatisierte Rechnungsverarbeitung, die Postsortierung, die Stapelverarbeitung von Dokumenten und alle Arbeitsabläufe, die Barcodes als physische Trennzeichen verwenden.

Wichtige Fakten, die Sie nicht verpassen sollten
DocName, DocContent, Barcode String, Barcode Filter, Barcode Type, Split Barcode Page, Combine Pages With Same Consecutive Barcodes, and Pdf Render Dpi are all required. Omitting any parameter causes the API to return an error or produce unexpected split results. Validate all eight fields before sending the request.
The API uses Barcode Type to select the correct recognition engine. Setting Code128 when the document contains QR Codes causes recognition to fail silently: the API returns the unsplit original document because no barcodes matched. Always verify the barcode format used in your documents before setting this parameter.
The API renders each page at the specified DPI before scanning for barcodes. At low DPI (e.g. 150), small or dense barcodes: such as DataMatrix or compact QR codes on A4 pages, may not resolve clearly enough for accurate decoding. Use 300 DPI as your default. Increase to 400-600 DPI only for very small barcodes; higher values increase processing time significantly.

Parameter
⚠️ Alle acht Parameter sind erforderlich. für korrektes Barcode-Erkennungs- und Aufteilungsverhalten.
| Parameter | Erforderlich | Typ | Was es tut | Beispiel |
|---|---|---|---|---|
| DocName | Required | String | Filename of the source PDF including the .pdf extension. Used for processing identification and output file naming. | batch-invoices.pdf |
| DocContent | Required | Base64 | The complete PDF file encoded as a Base64 string. The PDF must contain pages with machine-readable barcodes. | JVBERi0xLjQK... |
| Barcode String | Required | String | The barcode text or pattern to search for. Matched against decoded barcode values on each page using the Barcode Filter method. | INV- |
| Barcode Filter | Required | Enum | How the Barcode String is matched against decoded barcode text. Contains: text includes the string anywhere. Equals, exact match. StartsWith, text begins with the string. EndsWith, text ends with the string. | Contains |
| Barcode Type | Required | String | The barcode format printed in the PDF. Must match the actual barcode standard used. Common values: Code128 · Code39 · QRCode · EAN13 · EAN8 · DataMatrix · PDF417 | Code128 |
| Split Barcode Page | Required | Enum | Controls where the split occurs relative to the barcode page. Before: barcode page starts the next document. After, barcode page ends the current document. Remove, barcode page is excluded from all output. | After |
| Combine Pages With Same Consecutive Barcodes | Required | Boolean | When true, consecutive pages sharing the same barcode value are grouped into a single output document rather than split individually. Useful for multi-page forms where the same barcode appears on every page of a section. | true |
| Pdf Render Dpi | Required | String | DPI resolution for rendering PDF pages before barcode scanning. 300 is recommended for standard-size barcodes. Increase to 400-600 for small or dense barcodes. Higher DPI improves recognition accuracy but increases processing time. | 300 |

Häufige Anwendungsfälle
Accounts payable teams receive consolidated PDF batches where each invoice has a Code128 barcode separator page. Split at each barcode (Split Barcode Page: Remove) to extract individual invoice PDFs for routing to the correct cost centre or approval queue automatically.
Bulk print mail runs produce a single PDF with a barcode cover sheet per recipient. Split the document at each barcode page (Split Barcode Page: After) to extract individual mail pieces. Use the barcode value (address or route code) to name each split file for downstream sorting and physical printing.
Scanned document batches from physical mailrooms often include a QR code separator sheet between each document. Set Barcode Type: QRCode, Barcode Filter: Contains the archive category code, and Split Barcode Page: Remove to get clean content-only PDFs ready for archiving: with no separator stubs included.
Häufig gestellte Fragen
▶ What barcode types does the Split PDF by Barcode API support?
The API supports common 1D and 2D formats including Code128, Code39, QR Code, EAN-13, EAN-8, DataMatrix, and PDF417. Specify the correct type in Barcode Type: using the wrong type causes the recognition engine to miss all barcodes and return the unsplit original document.
▶ What does the Barcode Filter parameter control?
Barcode Filter controls how Barcode String is matched against decoded barcode text on each page. Contains: barcode text includes the string anywhere. Equals, exact match only. StartsWith, text begins with the string. EndsWith, text ends with the string. Use Contains for partial patterns, Equals for strict control over exact barcode values.
▶ What does Split Barcode Page control?
Split Barcode Page determines what happens to the page containing the matching barcode. Before: that page starts the next output document. After, that page ends the current output document. Remove, that page is excluded from all output documents entirely. Use Remove for blank separator pages or cover sheets you do not want in any output.
▶ What does Combine Pages With Same Consecutive Barcodes do?
When set to true, consecutive pages sharing the same barcode value are grouped into one output document instead of being split individually. This is useful for multi-page records or forms where the same barcode appears on every page of a section: it prevents unnecessary splits within a single logical document.
▶ Why should I increase Pdf Render Dpi for small or dense barcodes?
The API renders each PDF page at the specified DPI before scanning. At 150 DPI, small barcodes (e.g. DataMatrix cells under 5mm wide) may not resolve with enough pixel density for accurate decoding. Use 300 DPI as your default. Increase to 400-600 DPI for very small or dense barcodes: note that higher DPI significantly increases processing time and memory usage.
