It includes features for accounting, financial management, project management, and more, allowing businesses to streamline their operations and manage various aspects of their business in one integrated platform. Refer to our website for [the list of metrics and attributes available in Dataddo](https://dataddo.com/connector/exact_online). Refer to Exact Online's official documentation to see [all available endpoints from the Exact Online API](https://start.exactonline.nl/docs/HlpRestAPIResources.aspx?SourceAction=10). ## Authorize Connection to Exact Online To authorize this service, use **OAuth 2.0** to share specific data with Dataddo while keeping usernames, passwords, and other information private. 1. On the **Authorizers** page, click on [Authorize New Service](https://app.dataddo.com/service/new) and select your service. 2. Follow the on-screen prompts to grant Dataddo the necessary permissions to **access and retrieve** your data. 3. **[Optional]** Once your ***authorizer*** is created, click on it to **change the label** for easier identification. Ensure that the account you're granting access to holds at least **admin-level permissions**. If necessary, assign a team member with the required permissions with the [authorizer role](https://docs.dataddo.com/docs/user-roles#authorizer) to authenticate the service for you. For more information, see our article on [***{{glossary.authorizer}}s***](https://docs.dataddo.com/docs/authorized-services). ## How to Create an Exact Online Data Source 1. On the **Sources** page, click on the [**Create Source**](https://app.dataddo.com/sources/new) button. 2. Select the connector from the list and name your ***data source***. 3. On the **Dataset** step, select your **dataset**. **DATADDO TIP** If you're unsure which dataset to select, use the search bar to look for datasets with the desired attributes or metrics. 4. On the **Account** step select your ***authorizer*** from the drop-down menu. **Didn't find your authorizer?** Click on **Add new Account** at the bottom of the drop-down and follow the on-screen prompts. You can also go to the **Authorizers** tab and click on [**Add New Service**](https://app.dataddo.com/service/new). 5. On the **Attributes and Metrics** step, select the **metrics and attributes** you want to extract. ![Create a source using a custom-schema connector.](https://cdn.document360.io/084ed225-3f99-4644-a2da-39ca0cd5ef45/Images/Documentation/Create%20Source%20-%20Custom-Schema%20Connector.png) 6. On the **Metadata** step, select which [**metadata fields**](/docs/metadata-inclusion) such as extraction time to add to your data. 7. On the **Snapshot** step: 1. Configure your [**sync frequency**](/docs/extraction#extraction-frequency) or click **Show advanced settings** to set the exact synchronization time. **DATADDO TIP** To **load historical data**, refer to the [**Data Backfilling**](https://docs.dataddo.com/docs/data-backfilling) article. 2. [Optional] Enable the **Allow Empty Data Extractions** toggle to allow the extraction when no data is available. 8. In the top-right corner, click **Test Data** button to preview extracted data. **Adjust the date range** for specific time frame. 9. Click on **Save** and **congratulations, your new data source is ready!** --- ## Troubleshooting ### Data Preview Unavailable No data preview when you click on **Test Data** might be caused by an issue with your ***source*** configuration. The most common causes are: - **Date range**: Try a smaller date range. You can load the rest of your data afterward via [manual data load](https://docs.dataddo.com/docs/data-backfilling). - **Insufficient permissions**: Please make sure your authorized account has at least admin-level permissions. ### Authorization Issues with .be, .fr, .co.uk Accounts By default, the Dataddo Exact Online connector is pointed to the `.nl` version. So in case you did not [authorize the connection](/docs/authorized-services) to Exact Online yet, you will be redirected to an authorizer requesting the `.nl` version. If you have one of the `.be`, `.fr`, or `.co.uk` versions, please follow these steps: 1. In your Exact Online, navigate to **Settings**. 2. Go to the **Connected Accounts** section and select the correct national version of Exact Online. 3. Continue with your ***data source*** creation in Dataddo. ### Discrepancy In Exact Online Sync Datasets By default, when the source is created from the Sync endpoints, the URL contains these filters: Timestamp ge and Timestamp le part, example below: https://start.exactonline.{{country}}/api/v1/{{divisionId}}/sync/Financial/TransactionLines?$filter=Timestamp ge {{syncTimestampStart}}L and Timestamp le {{syncTimestampEnd}}L These filters are useful when you would like to do data backfill for a select period for the Exact Online sources. After data backfill is completed, you may now want to get the data for the current day, in this case, please remove the Timestamp le from the URL and set the date range of the source to 0d0. Example of the updated URL: https://start.exactonline.{{country}}/api/v1/{{divisionId}}/sync/Financial/TransactionLines?$filter=Timestamp ge {{syncTimestampStart}}L This will ensure that all of the data for the current day is up to date. Also, please use Upsert write mode in the flow if you plan on syncing this source on an hourly basis into your destination. ## Related Articles Now that you have successfully created a ***data source***, see how you can connect your data to a dashboarding app or a data storage. **Sending Data to Dashboarding Apps** - [Simple Data Integration to Dashboards](https://docs.dataddo.com/docs/simple-data-integration-to-dashboards) - [Data Backfilling to Dashboarding Apps](https://docs.dataddo.com/docs/data-backfilling-to-dashboarding-apps) **Sending Data to Data Storages** - [Batch Ingestion to Data Warehouses](https://docs.dataddo.com/docs/ingestion-to-data-warehouses) - [Data Backfilling to Storages](https://docs.dataddo.com/docs/data-backfilling-to-storages) **Other Resources** - [Troubleshooting](https://docs.dataddo.com/docs/troubleshooting) - [Extraction Logs](https://docs.dataddo.com/docs/extraction-logs) - [Data Duplication](https://docs.dataddo.com/docs/data-duplication)
