# 1. Generate Merchant Keys

API Endpoints

{% tabs %}
{% tab title="Production Endpoint" %}

```
Production Base URL /api/GenToken/GenerateMerchantKey
```

{% endtab %}

{% tab title="Sandbox Endpoint" %}

```
Sandbox Base URL /api/GenToken/GenerateMerchantKey
```

{% endtab %}
{% endtabs %}

#### **Sample Request & Response**

Use the below parameters to get merchant keys.

{% tabs %}
{% tab title="Sample Request" %}

```

{
    "merchantCode":"xxxxx",
    "authKey":"xxxxxxxxxx"
}
```

{% endtab %}

{% tab title="Sample Response" %}

```
{
  "errorCode": 0,
  "errorMessgae": "string",
  "result": {
    "publicKey": "string"
  }
}
```

{% endtab %}
{% endtabs %}

#### To obtain the public key, access the publicKey property directly from the API response object as follows:       

```
var publicKey = response.result.publicKey;
```

In the event that an error occurs while retrieving or using response.result.publicKey (e.g., the property is malformed, or inaccessible), implement the following fallback mechanism:                                                 **Use an RSA public key in the XML format specified below:**

```
<RSAKeyValue>
    <Modulus>[Binary value]</Modulus>
    <Exponent>AQAB</Exponent>
</RSAKeyValue>
```

&#x20;Replace \[Binary value] with the base64-encoded modulus of the RSA public key. This is the primary component of the key.

**Note**: Merchant keys are valid for 24 hours and the same key to be use for decryption for 24 hours. Users are expected to generate a new merchant key every 24 hours. If the merchant utilizes an invalid RSA public key, the following error will show up in subsequent calls. { "ErrorMessage" : "Exception while decrypting the Card Details" }
