# FAQ

Quick answers to the questions we hear most about the Cashfree gateway for AcelleMail.

## What's the difference between the two gateways?

The **Cashfree** gateway takes **one-time** invoice payments through Cashfree's Drop-in checkout. The
**Cashfree Subscription** gateway bills **recurring** plans using UPI AutoPay, eNACH or card mandates.
Use Cashfree for single invoices and Cashfree Subscription for anything that repeats.

## Which payment methods are supported?

**UPI, credit/debit cards, net banking and wallets** — all through Cashfree's hosted checkout.

## What currency can I charge in?

**INR only.** Cashfree's domestic Payment Gateway and Subscriptions are INR-based, so only INR-priced
plans are eligible. A subscription plan priced in any other currency won't be offered.

## Do I need to configure two gateways or one?

You configure your credentials **once**. In **Admin → Plugins → Cashfree → Settings** you enter the
license, App ID, Secret Key and Sandbox toggle a single time, and **both** gateways share them. The
only per-gateway step is mapping plans for the Subscription gateway.

## What's the difference between Sandbox and live?

The **Sandbox** checkbox chooses the environment, not your keys. Tick **Sandbox** with **Test** keys
(App ID begins with `TEST`) while testing; untick it and use **Production** keys when you go live.
Always run a small live payment after switching. See [Going live](/cashfree-acellemail/guides/going-live).

## Are my customers' card details stored?

**No.** Payment happens on Cashfree's **hosted checkout**, so card and account details are entered on
Cashfree, not in AcelleMail. The plugin confirms outcomes server-side and never stores card data.

## How are updates delivered?

**Manually.** There's no in-app updater — you download the new version from your relyweb.co client area
and upload it via **Admin → Plugins → Upload Plugin**. Your settings are preserved. See
[Updating](/cashfree-acellemail/updating).

## What happens if my license lapses?

The gateways stop appearing in **Admin → Payment Gateways** and payment processing is disabled. At
checkout a lapsed license shows **"Cashfree plugin license is not active. Please contact the
administrator."** The check is a local background check, so brief outages are tolerated — re-enter and
re-save your key to restore. See [Licensing](/cashfree-acellemail/licensing).

## Why do I have to map subscription plans?

Cashfree has **no "list all plans" API**, so plans can't be auto-discovered. You create each plan in
the Cashfree dashboard, copy its `plan_id`, and map it to your AcelleMail plan (same currency and
amount). See [Set up subscriptions](/cashfree-acellemail/guides/set-up-subscriptions).
