# What is EaaS? (https://docs.chargeflow.io/docs/platforms/eaas/introduction)



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 [#who-its-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 [#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 [#entitlement-gating]

EaaS access is **enabled per platform by your Chargeflow account manager**. You cannot self-serve enable it.

<Callout type="warn" title="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.
</Callout>

Once enabled, you can generate API keys, subscribe to webhooks, and start testing immediately.
