# AutoBill.fetchCreditHistory

The `fetchCreditHistory` method returns an array of `CreditEventLog` objects.

For more information, see the Account object’s [Account.fetchAllCreditHistory](Account_fetchAllCreditHi) method, and the [CreditEventLog Object Data Members](Account_fetchAllCreditHi) table.

## Input

*srd*: sparse response description, a SOAP string (which must be a JSON object), in which you specify the elements you want returned.This parameter enables the calling system to constrain a `method` call to return only components you specify. This gives you greater control over returned content, and improves response time within the Vindicia platform by reducing the processing needed for the call.

Some fields are required, either practically or in the WSDL, and will be returned regardless of the `srd` `A null` `srd` returns the complete response.

*autobill* : the (optional) `AutoBill` object for which you wish to retrieve credit event history. Use the `AutoBill`’s or `VID` to identify it. Leave this variable blank if you wish to fetch credit history across all `AutoBills`.

*timestamp*: the starting time stamp (lower limit) for the range of credit event logs you wish to retrieve.

*endTimestamp*: the ending time stamp (upper limit) for the range of credit event logs you wish to retrieve.

*page*: the page number, starting at 0, for which to return the results. For example, if the total number of results is 85 and *pageSize* is 10:

* Specifying 0 for *page* gets the results from 1 through 10.
* Specifying 2 for *page* gets the results from 21 through 30.
*

*pageSize*: the number of records to return per call. This value must be greater than 0.

## Output

*return*: an object of type `Return` that indicates the success or failure of the call.

*creditEventLogs*: an array of `CreditEventLog` objects. Each of these objects describes a specific credit-related event or action associated with the input `AutoBill`. See [CreditEventLog Object Data Members](Account_fetchAllCreditHi) for details.

## Returns

In addition to those listed in [The Return Object](The_Return_Object), this call returns:

| Return Code | Return String |
| - | - |
| `400` | One of the following: - `Unable to load autobill.` - `Invalid value or values of the time stamp, and/or page, and/or page size.` |
| `404` | `No matching credit events found.` |

## Example

```

// to fetch credit history for an AutoBill
$abill = new AutoBill(); 
// autobill id for an existing customer whose
// credit history you want to retrieve
$abill->setMerchantAccountId('jdoe101');
$page = 0; // paging begins at 0
$pageSize = 5; // five records 
$startTime = '2010-01-01T22:34:32.265Z'; 
$endTime = '2010-01-30T22:34:32.265Z'; 
do { 
   $ret = 
      $abill->fetchCreditHistory($startTime, $endTime $page, $pageSize); 
   $count = 0; 
   if ($ret['returnCode'] == 200) { 
      $fetchedLogs = $ret['creditEventLogs']; 
      $count = sizeof($fetchedLogs); 
      foreach ($fetchedLogs as $log) { 
         $credit = $log->getCredit();
         $ts = $log->getTimeStamp();
         $eventType = $log->getType();
         // process retrieved credit event log
         // details here.
      } 
      $page++; 
   } 
} while ($count > 0);
```
