November 6, 2026

New Features

Convert InDesign to IDML API

• Convert an InDesign document to IDML: New POST /v3/convert-indesign-to-idml endpoint converts an INDD file to IDML. View endpoint documentation. See Working with the Convert InDesign to IDML API for a quickstart.

Advanced Data Merge API

• New endpoint: POST /v4/merge-data merges CSV data with InDesign templates and adds support for rules, copyfitting, folder output, and pre-signed URLs. View endpoint documentation
• Conditional Visibility and Dynamic Styling: The rulesFile parameter accepts a JSON rules file that can show or hide layers, frames, and placeholders, restyle and recolor content, replace text, and resize or move frames for each record. Learn more about conditional visibility and dynamic styling.
• Copyfitting: The copyfittingSettings object in params automatically reduces font size within defined limits to resolve overset text after a merge. Learn more about copyfitting.
• Folder Structure and Zipped Output: Organize merge outputs into a folder hierarchy using a CSV column prefixed with ~, and optionally compress the output using outputCompressMediaType. Learn more about folder structure and zipped output.
• Pre-signed URL Support in CSV: Set the presignedUrlsInDataSource parameter to true to supply pre-signed image URLs directly in the CSV Image columns (prefixed with @). The images are fetched during the merge. Learn more about pre-signed URL support.
• Output Path Structure: Unlike /v3/merge-data, the POST /v4/merge-data endpoint does not nest outputs in rangeN batch subfolders. All output files are saved in the resolved output folder, and duplicate file names get a (n) suffix. Learn more about output path variations.
• Parameter Name Change: The pagesPerDocument parameter from /v3/merge-data is named recordsPerFile in /v4/merge-data. The behavior is the same. Learn more about the parameter name change.

Adobe Fonts Enablement

• Adobe Fonts Free library support: The InDesign API can now resolve fonts from the Adobe Fonts Free library automatically through your Adobe entitlement, so you no longer need to upload or host those font files. To enable this feature, add a product profile with Fonts enabled to your API credential. Learn more about using Adobe Fonts.

Enhancements

• Multiline records support in DataMerge: The POST /v3/merge-data and POST /v3/merge-data-tags endpoints now support and correctly process multiline records. Multiline content can be included by enclosing field values in double quotes (""), and any line breaks within those values will be preserved during processing. Learn more about multiline support.

• UTF-8 encoded CSV file support: The POST /v3/merge-data and POST /v3/merge-data-tags endpoints now accept and process UTF-8 encoded CSV files, enabling support for special characters such as emojis and international text. Learn more about UTF-8 support.

• HTML5 Export using custom scripts: Using a custom script, users can now export HTML5 pages from InDesign API.

  doc.html5ExportPreferences.textExportFormat = TextExportFormatEnum.HTML_TAG;
  doc.exportFile(ExportFormat.HTML5, html_File_path);
