The most common causes are: - **Date range**: Try a smaller date range. You can load the rest of your data afterward using [manual data load](https://docs.dataddo.com/docs/data-backfilling). - **Insufficient permissions**: Please make sure your authorized account has at least admin-level permissions. - **Invalid metrics, attributes, or breakdowns**: You may not have any data for the selected metrics, attributes, or breakdowns. - **Incompatible combination of metrics, attributes, or breakdowns**: Your selected combination cannot be queried together. Please refer to the service's documentation to view a full list of metrics that can be included in the same ***data source***. ## 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) An API token is a code snippet used to secure API access. It's sent to API servers as identification, confirming whether the user or application has access, and provides both authentication and user/application information to the API server. Authorizers act as credentials for external services (e.g. Facebook or Google). To enable Dataddo to access and retrieve your data, you need to grant access to accounts that possess admin-level permissions or higher within these services.
