What is EaaS?
Evidence-as-a-Service turns dispute data into a bank-ready, versioned PDF evidence package via API - a platform-level integration for B2B platforms and PSPs.
Evidence-as-a-Service (EaaS) transforms messy dispute data into a polished, bank-ready PDF evidence package in about 30 seconds (up to ~3 minutes). Your platform provides the dispute details and supporting materials; Chargeflow's AI agent enriches, validates, and assembles a consistent evidence letter designed to refute the claim. Once ready, Chargeflow notifies you via webhook and provides a secure download link for the PDF.
Who it's for
EaaS is designed for B2B platforms and PSPs, not individual merchants.
- Platforms integrate EaaS by exposing a "Generate Evidence" action in their merchant portal, or by triggering evidence generation automatically when disputes arrive.
- Merchants do not integrate directly with EaaS. Merchants on your platform can manage disputes through Chargeflow by connecting their payment providers, but the EaaS API itself is a platform-level integration.
Key capabilities
- Works for all disputes: any stage, any country, any language.
- Rich context support: leverages dispute data, enrichments, and optional merchant context such as policies, checkout steps, and buyer verification details.
- Single versioned PDF: outputs one document per dispute, ready for bank submission.
- Version control: regenerate evidence as new data arrives; each regeneration increments
file_version. - Structured data access: enriched dispute data is accessible via API alongside the PDF.
Entitlement gating
EaaS access is enabled per platform by your Chargeflow account manager. You cannot self-serve enable it.
Warning
Without the EaaS entitlement, all EaaS API calls return a 403_eaas_not_enabled error. Contact your account manager to get EaaS enabled on your Connect account before testing.
Once enabled, you can generate API keys, subscribe to webhooks, and start testing immediately.
