# FAQ

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

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

* **Cashfree:** Handles one-time invoice payments through Cashfree's Drop-in checkout.
* **Cashfree Subscription:** Manages recurring plans using UPI AutoPay, eNACH, or card mandates.

## 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?

Configure credentials **once** under **Admin → Plugins → Cashfree → Settings**:

* **Shared configuration:** License key, App ID, Secret Key, and Sandbox toggle apply to both gateways.
* **Subscription requirement:** Remote plan mappings are configured separately under **Admin → Remote Plan Mappings**.

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

The **Sandbox** checkbox determines the target API endpoint:

* **Testing (ticked):** Use with Test keys (App ID begins with `TEST`).
* **Live (unticked):** Use with Production credentials.

Verify with a low-value test transaction 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?

* **Gateway status:** Gateways disappear from **Admin → Payment Gateways** and payment processing stops.
* **Customer error:** Checkout shows: *"Cashfree plugin license is not active. Please contact the administrator."*
* **Restoration:** Re-enter and save a valid license key. Brief network outages are tolerated by local caching. See [Licensing](/cashfree-acellemail/licensing).

## Why do I have to map subscription plans?

Cashfree lacks an API endpoint to list all merchant plans automatically:

* **Create:** Configure the plan in Cashfree Dashboard and copy its `plan_id`.
* **Map:** Link the `plan_id` to the matching AcelleMail plan (same currency and amount) in **Admin → Remote Plan Mappings**. See [Set up subscriptions](/cashfree-acellemail/guides/set-up-subscriptions).
