Response

It returns a converted document in one of the following formats (in order of preference), depending on the Accept header:

• application/octet-stream
• text/plain
• application/json

If the result is a binary format (e.g., epub or docx) and the content is returned as plain text or JSON, the binary will be base64 encoded.

If a JSON response is given, it will have one of the following formats. If the conversion is not successful:

{ "error": string with the error message }

If the conversion is successful:

{ "output": string with textual or base64-encoded binary output,
  "base64": boolean (true means the "output" is base64-encoded),
  "messages": array of message objects (see below) }

Each element of the “messages” array will have the format

{ "message": string,
  "verbosity": string (either "WARNING" or "INFO") }

Request

The body of the POST request should be a JSON object, with the following fields. Only the text field is required; all of the others can be omitted for default values. When there are several string alternatives, the first one given is the default.

text (string)

The document to be converted. Note: if the from format is binary (e.g., epub or docx), then text should be a base64 encoding of the document.

from (string, default "markdown")

The input format, possibly with extensions, just as it is specified on the pandoc command line.

to (string, default "html")

The output format, possibly with extensions, just as it is specified on the pandoc command line.

shift-heading-level-by (integer, default 0)

Increase or decrease the level of all headings.

indented-code-classes (array of strings)

List of classes to be applied to indented Markdown code blocks.

track-changes ("accept"|"reject"|"all")

Specifies what to do with insertions, deletions, and comments produced by the MS Word “Track Changes” feature. Only affects docx input.

abbreviations (file path)

List of strings to be regarded as abbreviations when parsing Markdown. See --abbreviations in pandoc(1) for details.

standalone (boolean, default false)

If true, causes a standalone document to be produced, using the default template or the custom template specified using template. If false, a fragment will be produced.

template (string)

String contents of a document template (see Templates in pandoc(1) for the format).

variables (JSON map)

Variables to be interpolated in the template. (See Templates in pandoc(1).)

dpi (integer, default 96)

Dots-per-inch to use for conversions between pixels and other measurements (for image sizes).

wrap ("auto"|"preserve"|"none")

Text wrapping option: either "auto" (automatic hard-wrapping to fit within a column width), "preserve" (insert newlines where they are present in the source), or "none" (don’t insert any unnecessary newlines at all).

columns (integer, default 72)

Column width (affects text wrapping and calculation of table column widths in plain text formats)

table-of-contents (boolean, default false)

Include a table of contents (in supported formats).

toc-depth (integer, default 3)

list-of-figures (boolean, default false)

Include a list of figures (in supported formats).

list-of-tables (boolean, default false)

Include a list of tables (in supported formats).

strip-comments (boolean, default false)

Causes HTML comments to be stripped in Markdown or Textile source, instead of being passed through to the output format.

highlight-style (string, leave unset for no highlighting)

Specify the style to use for syntax highlighting of code. Standard styles are "pygments" (the default), "kate", "monochrome", "breezeDark", "espresso", "zenburn", "haddock", and "tango". Alternatively, the path of a .theme with a KDE syntax theme may be used (in this case, the relevant file contents must also be included in files, see below).

embed-resources

Embed images, scripts, styles and other resources in an HTML document using data URIs. Note that this will not work unless the contents of all external resources are included under files.

html-q-tags (boolean, default false)

Use <q> elements in HTML instead of literal quotation marks.

ascii (boolean, default false)

Use entities and escapes when possible to avoid non-ASCII characters in the output.

reference-links (boolean, default false)

Create reference links rather than inline links in Markdown output.

reference-location ("document"|"section"|"block")

Determines whether link references and footnotes are placed at the end of the document, the end of the section, or the end of the block (e.g. paragraph), in certain formats. (See pandoc(1) under --reference-location.)

setext-headers (boolean, default false)

Use Setext (underlined) headings instead of ATX (#-prefixed) in Markdown output.

top-level-division ("default"|"part"|"chapter"|"section")

Determines how top-level headings are interpreted in LaTeX, ConTeXt, DocBook, and TEI. The "default" value tries to choose the best interpretation based on heuristics.

number-sections (boolean, default false)

Automatically number sections (in supported formats).

number-offset (array of integers)

Offsets to be added to each component of the section number. For example, [1] will cause the first section to be numbered “2” and the first subsection “2.1”; [0,1] will cause the first section to be numbered “1” and the first subsection “1.2.”

html-math-method ("plain"|"webtex"|"gladtex"|"mathml"|"mathjax"|"katex")

Determines how math is represented in HTML.

listings (boolean, default false)

Use the listings package to format code in LaTeX output.

incremental (boolean, default false)

If true, lists appear incrementally by default in slide shows.

slide-level (integer)

Heading level that deterimes slide divisions in slide shows. The default is to pick the highest heading level under which there is body text.

section-divs (boolean, default false)

Arrange the document into a hierarchy of nested sections based on the headings.

email-obfuscation ("none"|"references"|"javascript")

Determines how email addresses are obfuscated in HTML.

identifier-prefix (string)

Prefix to be added to all automatically-generated identifiers.

title-prefix (string)

Prefix to be added to the title in the HTML header.

reference-doc (file path)

Reference doc to use in creating docx or odt or pptx. See pandoc(1) under --reference-doc for details. The contents of the file must be included under files.

epub-subdirectory (string, default “EPUB”)

Name of content subdirectory in the EPUB container.

epub-fonts (array of file paths)

Fonts to include in the EPUB. The fonts themselves must be included in files (see below).

ipynb-output ("best"|"all"|"none")

Determines how ipynb output cells are treated. all means that all of the data formats included in the original are preserved. none means that the contents of data cells are omitted. best causes pandoc to try to pick the richest data block in each output cell that is compatible with the output format.

citeproc (boolean, default false)

Causes citations to be processed using citeproc. See Citations in pandoc(1) for details.

bibliography (array of file paths)

files (JSON mapping of file paths to base64-encoded strings)

Any files needed for the conversion, including images referred to in the document source, should be included here. Binary data must be base64-encoded. Textual data may be left as it is, unless it is also valid base 64 data, in which case it will be interpreted that way.
