Hello FreeAgent API forum!

I would like to update the type of a bank transaction explanation. The [docs](https://dev.freeagent.com/docs/bank_transaction_explanations) don’t go into enough detail unfortunately. For example: an explanation has a type of “Payment” with a category of 280 and I want to update it with `PUT` to an explanation with a type of “Money paid to user”, a category of 907 and (an additional field for this type) a paid user of 706069. If I try this:

```
PUT https://api.freeagent.com/v2/bank_transaction_explanations/167295407
{
    "bank_transaction_explanation": {
        "category": "https://api.freeagent.com/v2/categories/907",
        "is_money_paid_to_user": true,
        "paid_user": "https://api.freeagent.com/v2/users/706069"
    }
}

```

I get the following response:

```
400 Bad Request
{
    "errors": {
        "error": {
            "message": "unknown attribute 'category' for BankAccountEntry."
        }
}

```

}

Confusing! I have a large batch of these to update, so any help would be much appreciated.

Thanks.

Hi Ben,

Apologies, the error message is indeed misleading. It looks like the underlying cause is the missing `gross_value` parameter. The following request should work:

```auto
PUT https://api.freeagent.com/v2/bank_transaction_explanations/167295407
{
   "bank_transaction_explanation" : {
      "gross_value" : [AMOUNT]
      "category" : "https://api.freeagent.com/v2/categories/907",
      "paid_user" : "https://api.freeagent.com/v2/users/706069"
   }
}

```

Thanks,

Anup
