Renders the template once per element of an array in the data and returns the files in a ZIP.

splitBy names the array with a dotted path such as items or order.lines. Each render sees the whole data with that array replaced by the one element, plus item (the element) and batch (index, count). batchName is a template for each file’s name, default {{ batch.index }}.

Request Body^required

The multipart form /v1/render, /v1/render/batch and /v1/templates/validate accept.

object

assets

Images (PNG, JPEG, GIF, SVG), stylesheets and fonts an HTML page names by file name, as in <img src="logo.png">. Every stylesheet applies to the whole page. Nothing is fetched from anywhere else.

Array<string>

batchName

For /v1/render/batch: each file’s name, as a template.

string | null

bookmarks

For bookmarks: a JSON array of {"title", "page", "children"} that replaces the outline, sent as text.

contactInfo

For sign: how to reach the signer.

string | null

ctx

JSON object visible as ctx, sent as text or as a file.

string | null

currency

The currency currency uses when given none, such as EUR. Wins over the template’s.

string | null

data

JSON object the template sees as its root, sent as text or as a file.

string | null

{"customer": {"name": "Ada"}}

downloadFrom

Files to fetch from URLs instead of uploading them, as a JSON array of {"url": "..."} sent as text. At most 10 entries.

Array<string>

embedsMetadata

For embed: a JSON object mapping a file name to {"mimeType": "..."}, sent as text.

For factur-x: MINIMUM, BASIC_WL, BASIC, EN16931 (default) or EXTENDED.

string | null

facturxXml

For factur-x: the invoice XML to embed.

string format: binary

files

Further files, used by merge.

Array<string>

flatten

With a PDF template and data, true fixes the filled values into the page.

What turns HTML into PDF: fulgur (default), a layout engine with no browser and no network, or libreoffice.

string | null

Example

fulgur

What an Office template’s result may keep of what rendering takes out, comma-separated: macros, objects (OLE objects and ActiveX controls), externalLinks, privateLinks (hyperlinks to private addresses), or all. Default: none of them.

string | null

Example

privateLinks

lang

The language, such as fr, fr-CA or en-us, in any case. It wins over the template’s lang: it picks translations for t, and when CLDR has data for it, how number, currency and date write numbers, money and month names.

string | null

Example

fr-CA

level

For sign: b-b, b-t, b-lt or b-lta, as on /v1/pdf/sign.

string | null

location

For sign: where it was signed.

string | null

metadata

JSON object of metadata fields for metadata, sent as text.

string | null

outputFilename

File name of the result, without extension.

string | null

ownerPassword

For encrypt: the password that lifts its restrictions. Defaults to userPassword.

string | null

For rotate: the pages to turn, such as 1-3. Default all.

string | null

string | null

signingKey

For sign: a named key instead of the default one.

string | null

splitBy

string | null

splitSpan

For split: page ranges such as 1-3,5 with pages, or a page count with intervals. Required by the step.

string | null

splitUnify

For split with pages: true gives one document holding the pages instead of one per range.

boolean | null

stamp

For stamp with an image or pdf source: the files to draw. At most five marks a request.

Array<string>

stampExpression

string | null

Example

convert,pdfa,encrypt

The template file. Send this or templateId.

string format: binary

templateHash

The hex SHA-256 of a template this caller sent recently, in place of the file.

string | null

templateId

The id of a stored template, from POST /v1/templates, or an alias as name or name@version. Send this or template. Files in the form are then only further inputs, for merge.

string | null

Example

Europe/Paris

Output format for convert. Default pdf.

string | null

translations

Translations for t, by language, each a flat object of keys and texts. They win over the service’s dictionaries and the template’s own. At most 10,000 entries, keys of 256 bytes and texts of 16 KiB.

The JSON body /v1/render, /v1/render/batch and /v1/templates/validate accept with Content-Type: application/json, for a stored template: there are no files to send.
