# Other Card Processors

> Setup steps for SumUp, Mollie, Skrill, Authorize.Net, Revolut Business, NMI, Overpay, MONEI, Razorpay, Mercado Pago, Adyen, VenPayr and OVGC Payments.

Every processor on this page takes card payments into an account you own. [Stripe](/guides/payment-methods/stripe), [Square](/guides/payment-methods/square) and [PayPal](/guides/payment-methods/paypal) have their own pages. The rest are covered below, and each is a matter of pasting in credentials, with some also needing a webhook.

If you are not sure which processor to choose, start with [How to accept card payments](/guides/accept-cards).

<Note>
  Where a webhook URL is needed it looks like `https://webhooks.sellauth.com/v1/PROVIDER/YOUR_SHOP_ID`. The exact URL with your shop ID filled in is shown in the setup instructions on the payment method page in the dashboard.
</Note>

## SumUp

Cards, plus Apple Pay and Google Pay with Hosted Checkout enabled.

<Steps>
  <Step title="Create an API key">
    On the [SumUp API Keys](https://developer.sumup.com/api-keys) page, name the key SellAuth and click **Create**. Copy it into **API Key**.
  </Step>

  <Step title="Find your merchant code">
    In the [SumUp dashboard](https://me.sumup.com/), your merchant code sits under your business name in the top right, in the form `M3J4YWRV`. Copy it into **Merchant Code**.
  </Step>
</Steps>

**Hosted Checkout** switches SumUp to its newer checkout, which supports Apple Pay and Google Pay and gives buyers a better flow. Leave it off and buyers get the older card form. SumUp also supports [currency override](/guides/payment-methods#settings-shared-by-every-method).

## Mollie

Cards, Apple Pay and Google Pay, plus iDEAL, Bancontact, BLIK, Klarna, TWINT, EPS, giropay, Przelewy24 and Multibanco. A good fit if you sell into the Netherlands, Belgium or Germany.

Paste your Mollie **API key** and save. Which local methods appear depends on what you have activated in Mollie and where the buyer is.

## Skrill Business

Cards, Apple Pay and Google Pay, plus local methods. Requires a Skrill **Business** account, as a personal account will not work.

Enter the email address on your Skrill Business account and save.

For a personal Skrill wallet, use [Skrill (Send Money)](/guides/payment-methods/skrill-send-money) instead, which detects wallet transfers from Skrill's notification emails.

## Authorize.Net

Cards only, with optional address collection.

<Steps>
  <Step title="Copy your API credentials">
    Open [API Credentials & Keys](https://account.authorize.net/ui/themes/anet/User/TransactionKey.aspx). Copy the **API Login ID**, then generate a **New Transaction Key** and a **New Signature Key**, copying each into the matching field.
  </Step>

  <Step title="Add the webhook">
    On the [Webhooks page](https://account.authorize.net/ui/themes/anet/Settings/Webhooks.aspx), click **Add Endpoint**, enter your SellAuth webhook URL, and under **Select Events** choose **Payment Events > net.authorize.payment.authcapture.created**. Save.
  </Step>
</Steps>

**Enable Billing Address Inputs** and **Enable Shipping Address Inputs** add those fields to the Authorize.Net checkout, which helps with fraud screening and with physical goods.

## Revolut Business

Cards, Apple Pay, Google Pay and Revolut.

Open [Settings > APIs > Merchant API](https://business.revolut.com/settings/apis?tab=merchant-api) in Revolut Business and copy the **API Public Key** and **API Secret Key** into the matching fields.

**Hosted Checkout** sends buyers to Revolut's site instead of showing the payment form in a popup. You can restyle the form under Revolut Checkout in the merchant profile settings.

## NMI

Cards only. Enter the **Terminal ID**, **Transaction Key** and **Hash Key** from your NMI account and save.

## Overpay

Cards only. Overpay approves integrations by application rather than self-signup, so contact them through [overpay.pro](https://overpay.pro) first.

Once approved, enter the **Shop ID**, **Public Key** and **Secret Key** from your Overpay account. Their [documentation](https://docs.overpay.io/en/using_api/id_key/) shows where to find each value.

## MONEI

Cards, Apple Pay and Google Pay. Popular in Spain.

Open [MONEI API Access](https://dashboard.monei.com/settings/api), click **Create API Key** or copy the existing one, paste it into **API Key** and save.

## Razorpay

UPI, cards and netbanking, for buyers in India. No Apple Pay or Google Pay.

<Steps>
  <Step title="Generate live API keys">
    On the [Razorpay API Keys page](https://dashboard.razorpay.com/app/website-app-settings/business-website-details), click **Generate Key**. Copy the **Live API Key** (it starts with `rzp_live_`) and the **Live Key Secret** into the matching fields.
  </Step>

  <Step title="Add the webhook">
    On the [Webhooks page](https://dashboard.razorpay.com/app/website-app-settings/webhooks), click **Add New Webhook** and enter your SellAuth webhook URL.
  </Step>

  <Step title="Set a matching secret">
    In Razorpay's **Secret** field, enter a random string of your choice. Paste the same string into **Webhook Secret** on the SellAuth page. The two must match.
  </Step>

  <Step title="Enable the events">
    Under **Active Events**, enable everything in the **Payment\_link** section, then save.
  </Step>
</Steps>

## Mercado Pago

Cards and local methods across Latin America. No Apple Pay or Google Pay.

Copy the **Access Token** from your Mercado Pago account, in the form `APP_USR-...`, and save. Mercado Pago supports [currency override](/guides/payment-methods#settings-shared-by-every-method).

## Adyen

Cards, Apple Pay and Google Pay, with a longer setup than most.

<Steps>
  <Step title="Create an API credential">
    In the Adyen dashboard, go to **Developers > API Credentials**, click **Create new credential**, choose **Web service user**, and create it. Copy the API key, then click **Save changes**.
  </Step>

  <Step title="Find your merchant account">
    Click your company name in the top left. It reads like `YourCompanyAccount / YourCompanyMerchantECOM`. The part after the slash is your merchant account.
  </Step>

  <Step title="Create the webhook">
    Go to **Developers > Webhooks**, click **Create new Webhook**, choose **Standard webhook** and click **Add**. Set the URL to your SellAuth webhook URL. Under **Security > HMAC**, click **Generate** and copy the key into **Webhook HMAC Key**. Under **Events**, click **Clear** and select only **AUTHORISATION**. Save the configuration.
  </Step>
</Steps>

## VenPayr

Cards, Apple Pay and Google Pay, settled to you in cryptocurrency.

In the [VenPayr dashboard](https://dash.venpayr.com/dashboard/payout-settings), scroll to **Store API Key** and click **Regenerate Key**. Copy it into **API Key**, then copy your **Username** from the same dashboard.

## OVGC Payments

Cards, Apple Pay and Google Pay, settled to you in cryptocurrency.

<Steps>
  <Step title="Create an API key">
    In the [OVGC dashboard](https://portal.ovgcpayments.com), go to **API keys** and click **Create Key**. Copy it into **API Key**.
  </Step>

  <Step title="Add the webhook">
    Go to **Webhooks**, click **Add Endpoint**, enter your SellAuth webhook URL, then copy the **Signing secret** into **Webhook Secret**.
  </Step>
</Steps>

## Troubleshooting

**The method cannot be selected at checkout.** The order total falls outside the minimum or maximum amount set on the method. Hovering the method at checkout gives the reason.

**Buyers pay but orders stay pending.** On any processor that needed a webhook, check the webhook first for a wrong URL, wrong events, or a secret that does not match.

**Payments fail immediately.** Test credentials were used instead of live ones, or the keys belong to a different account than the one named in the settings.
