Select **Gainsight** and click **Continue**. You can then authenticate Hightouch to Gainsight by entering the following fields into Hightouch: * **Subdomain**: You can create domains and subdomains by following [these instructions in Gainsight's docs](https://support.gainsight.com/Gainsight_NXT/06Surveys/02Admin_Guides/Set_up_a_Gainsight_Domain). * **API Key**: You can generate an API key by following [these instructions in Gainsight's docs](https://support.gainsight.com/Gainsight_NXT/Connectors/Connectors/API_Integrations/Generate_API_Access_Key#Generate_Access_Key). ## Sync configuration Once you've set up your Gainsight destination and have a [model](https://docs.hightouch.com/getting-started/concepts.md#models) to pull data from, you can set up your sync configuration to begin syncing data. Go to the [**Syncs** overview page](https://app.hightouch.com/syncs?from=docs) and click the **Add sync** button to begin. Then, select the relevant model and the Gainsight destination you want to sync to. ### Syncing companies The [Company object](https://support.gainsight.com/Gainsight_NXT/API_and_Developer_Docs/Company_and_Relationship_API/Company_API_Documentation) is one of the core objects in Gainsight and is used to store information about your customers, including individual customer records. #### Record matching To match rows from your model to companies in Gainsight, you need to select a model column and corresponding Gainsight field. You can match on any [filterable, unique](https://support.gainsight.com/Gainsight_NXT/API_and_Developer_Docs/Data_Management_APIs/Data_Management_APIs#Get_Describe_OMD) field in Gainsight. Refer to the [record matching docs](https://docs.hightouch.com/syncs/record-matching.md) for more information. #### Field mapping Hightouch lets you sync company fields via [field mapping](https://docs.hightouch.com/syncs/mapping-data.md). You can map data from any of your model columns to any non read-only company fields. #### Delete behavior The [delete behavior](https://docs.hightouch.com/syncs/overview.md#delete-behavior) you select dictates what to do when a row no longer appears in your model's query results. You have the following options: | Behavior | Description | | - | - | | **Do nothing** | Keep the company in Gainsight | | **Clear** | Remove all the mapped fields, but keep the record in Gainsight | | **Delete** | Delete the synced company record from Gainsight | ### Syncing people A Gainsight [Person](https://support.gainsight.com/Gainsight_NXT/API_and_Developer_Docs/Person_API/Person_API_Documentation) is a standard object that stores unique records of people in the real world. #### Record matching To match rows from your model to people in Gainsight, you need to select the model column that contains values that match the **Email** field. Refer to the [record matching docs](https://docs.hightouch.com/syncs/record-matching.md) for more information. #### Field mapping Hightouch lets you sync people fields via [field mapping](https://docs.hightouch.com/syncs/mapping-data.md). You can map data from any of your model columns to any non read-only people fields. #### Delete behavior The [delete behavior](https://docs.hightouch.com/syncs/overview.md#delete-behavior) you select dictates what to do when a row no longer appears in your model's query results. You have the following options: | Behavior | Description | | - | - | | **Do nothing** | Keep the person in Gainsight | | **Clear** | Remove all the mapped fields, but keep the record in Gainsight | | **Delete** | Delete the synced person record from Gainsight | ### Syncing custom objects Hightouch lets you update [Low Volume Custom Objects](https://support.gainsight.com/SFDC_Edition/Data_Management/Managing_Data_In_Gainsight/Low_Volume_Custom_Objects) in Gainsight. You can use these objects to store low volume data that needs to be edited frequently. Hightouch diplays Low Volume custom objects in your Gainsight instance in a picklist at the beginning of your sync configuration. To create custom objects, refer to [Gainsight's docs](https://support.gainsight.com/Gainsight_NXT/02Data_Management/Objects/Gainsight_Objects#Create_Low_Volume_Custom_Objects). > [!NOTE] > > Gainsight doesn't support creating or updating High Volume Custom Objects via [their API](https://support.gainsight.com/Gainsight_NXT/API_and_Developer_Docs/Custom_Object_API/Gainsight_Custom_Object_API_Documentation). > As a workaround, you can sync your data to [S3](https://docs.hightouch.com/destinations/s3.md) and use Gainsight's [S3 Connector](https://support.gainsight.com/SFDC_Edition/Connectors/Connectors/File-Based_Integration/Gainsight_S3_Connector) to import your data into a High Volume Custom Object. #### Record matching To match rows from your model to custom objects in Gainsight, you need to select a model column and corresponding Gainsight field. You can match on any [filterable, unique](https://support.gainsight.com/Gainsight_NXT/API_and_Developer_Docs/Data_Management_APIs/Data_Management_APIs#Get_Describe_OMD) field in Gainsight. Refer to the [record matching docs](https://docs.hightouch.com/syncs/record-matching.md) for more information. #### Field mapping Hightouch lets you sync custom object fields via [field mapping](https://docs.hightouch.com/syncs/mapping-data.md). You can map data from any of your model columns to any non read-only custom object fields. #### Delete behavior The [delete behavior](https://docs.hightouch.com/syncs/overview.md#delete-behavior) you select dictates what to do when a row no longer appears in your model's query results. You have the following options: | Behavior | Description | | - | - | | **Do nothing** | Keep the custom object in Gainsight | | **Clear** | Remove all the mapped fields, but keep the record in Gainsight | | **Delete** | Delete the synced custom object from Gainsight | ## Tips and troubleshooting To see the exact API requests and responses from each sync run, use the [live debugger](https://docs.hightouch.com/syncs/debugger.md). To get notified by Slack, PagerDuty, SMS, or email when a sync fails, set up [sync alerts](https://docs.hightouch.com/syncs/alerting.md). If you run into an issue this page doesn't cover, [contact support](#pylon-chat).
