# Account Details Are Missing

## Overview

**400 - Bad Request:**  This error occurs when the request payload for disbursements is missing required account details necessary for processing.

```json theme={null}
{
    "success": false,
    "message": "Account details are missing."
}
```

## Common Causes and How to Resolve

1. **Missing Payment Details**:
   Missing the required payment details for a specific payment method may result in this error. For instance, in a KES till number disbursement, the request payload below would trigger an error because the till number value is missing, even though it is mandatory for this payment method.

```json theme={null}
{
        "client_id": "XXxxXX",
        "params": {
            "tillnumber": [
                {
                    "till_number": null
                }
            ],
            "amount": "10000",
            "city": "CustomerCity",
            "client_callback_url": "https://example.com",
            "country_id": "1",
            "currency": "KES",
            "email": "johndoe@example.com",
            "first_name": "JohnDoe",
            "last_name": "123",
            "line1": "CustomerStreet",
            "mobile": "2547xxxxxxx0",
            "payment_reference": "REF",
            "postal_code": "123"
        },
        "salt": "salt_value",
        "sender": "integration_name",
        "timestamp": XXxxXX,
        "signature": "XXxxXX"
    }
```

**How To Resolve**: Double-check the required fields for the specified payment method in the API reference for [disbursements](/api-reference/payment/niobi-unified-payment-version-3).

## Best Practices

* **Always Include Required Fields**:
  * Verify from the API documentation the list of required account or payment related details before sending a request.

* **Validate Input Fields**:
  * Implement validation on the client side to ensure all necessary account details are included before submitting the request to avoid missing fields.
