## Working with source settings

Settings on this page are summarised below:

| Field            | Summary                                                                                                                                                                                                                                                                                                                                                                                                                                                     |
| ---------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Source system    | The system that is defined as the source for this service (e.g. Shopify). When this service runs, data is pulled from this system.                                                                                                                                                                                                                                                                                                                          |
| Environment      | <p>When a <a href="/pages/nGdgsIG4bbzprkwE8YrF">connector is added</a>, you can choose whether it is to be used in a live environment, or for testing (also known as staging). </p><p></p><p>The environment is set at the connector level and cannot be changed here. If you need to use a different environment than the one specified here, make sure that a connector exists with the required environment setting and add a new service to use it.</p> |
| Page size        | The number of records to be pulled from the source system at a time. Typically, this value should be left as per the default setting.                                                                                                                                                                                                                                                                                                                       |
| Maximum attempts | The number of times that the service will retry pushing a record if it fails to sync for any reason.                                                                                                                                                                                                                                                                                                                                                        |
| Time zone        | Primarily used for time-based filters (e.g. syncing orders created after a given date/time). Patchworks uses UTC but a specific time zone can be applied here if needed.                                                                                                                                                                                                                                                                                    |
