# Sandbox (https://docs.chargeflow.io/docs/merchants/sandbox)



<ComingSoon href="/docs/reference/api-fundamentals/test-credentials">
  An isolated sandbox for merchant integrations is on the way. It will let you build and validate
  against seeded test disputes and alerts without touching production data, with seeded scenarios
  (won, lost, representment, alert prevented) and an in-page API explorer. Interactive, runnable
  tutorials will ship alongside it.
</ComingSoon>

Until the sandbox ships, build against the live API with care.

## Build safely before the sandbox [#build-safely-before-the-sandbox]

1. Generate API keys from the [Chargeflow App](https://app.chargeflow.io/settings#developers), see [API keys](https://docs.chargeflow.io/docs/reference/api-fundamentals/test-credentials).
2. Read disputes and alerts before you write, so you can confirm response shapes without side effects.
3. Make your first call with the [Quickstart](https://docs.chargeflow.io/docs/merchants/quickstart).
4. Work through the [Go-live checklist](https://docs.chargeflow.io/docs/reference/api-fundamentals/go-live-checklist) before you send production traffic.

## What you will be able to test [#what-you-will-be-able-to-test]

* Authentication against `https://api.chargeflow.io` using the `x-api-key` header.
* List and read disputes with [pagination](https://docs.chargeflow.io/docs/reference/api-fundamentals/pagination), and fetch a single dispute by ID.
* Upload evidence, following [Upload evidence](https://docs.chargeflow.io/docs/merchants/automation/upload-evidence).
* Pre-chargeback alerts, following [Manage alerts](https://docs.chargeflow.io/docs/merchants/alerts/manage-alerts).
* Webhooks for `dispute.created` and alert events, following [Subscribe to events](https://docs.chargeflow.io/docs/merchants/automation/subscribe-to-events).
