What is email-body-converter-reference?

Reference material for Rossum's Email Body Converter, a hosted webhook that turns an email's HTML body into a PDF document for Rossum to process. A webhook is a service that runs when an event occurs, such as receiving an email.

Setting up the converter, choosing its configuration, converting selected HTML or text attachments, and designing rules for when the email body should be processed.

Rossum normally processes email attachments but not the email body itself, so this helps make invoice or order data in the body available for extraction.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00313	$0.00821
Opus 5.5	$0.00125	$0.00328
Sonnet 5.5	$0.00063	$0.00164
Haiku 4.5	$0.00031	$0.00082

Security

Grade A, and why

email-body-converter-reference scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Email Body Converter Reference

The Email Body Converter is a Rossum-maintained hosted webhook ("A simple extension that can convert the email HTML body into a PDF and upload it to a queue as a new document") that exists to work around a platform default: "Rossum does not process the body of the email itself" — only attachments are imported. When the invoice, order, or other data arrives in the email body, this extension renders the body as a PDF so it enters the queue as a normal document and gets extracted. It can also convert HTML/TXT attachments to PDF, and (via a second, undocumented mode) HTML/TXT uploads.

See reference.md for the full reference. Consult it when:

Setting the extension up — it is a manually created Webhook on email.received pointing at a Rossum-hosted service URL, with a region table (EU1 + US only) and an admin token owner requirement.
Choosing settings — all 12 configurations[] keys, including the seven that the KB article does not document (each tagged by how it was verified).
Building "convert the body only when nothing else is processable" recipes (skip_if_supported_files_present), attachment conversion, or PDF styling.
Wiring the upload.created → /convert-files mode to convert uploaded HTML/TXT files.
Troubleshooting: body-only emails bouncing as "no processable attachments", nothing imported, replies being converted, attachments not converting.

Read this first: the extension is not in the Rossum Store — you create the webhook yourself (Extensions → My extensions). The service is hosted in EU1 and US; orgs in other regions (EU2 Frankfurt, Japan Tokyo) point their webhook at one of those URLs cross-region. The webhook needs a token owner with Admin access.

Cross-references:

rossum-reference — inbox/email API, the email.received payload/response contract, and the field-level email sources (email_body:text_html, email_header:subject, email:* in rir_field_names) which populate fields on an existing annotation; this extension instead creates a new document.
sfi-reference — structured XML/JSON/e-invoice import (a different extension for machine-readable formats).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
