It allows businesses to send targeted messages and emails to their users based on specific events, actions, or attributes, helping them create more engaging and tailored user experiences. Refer to our website for [the list of metrics and attributes available in Dataddo](https://www.dataddo.com/connector/customer_io). Refer to Customer.io's official documentation to see [all available endpoints from the Customer.io API](https://www.customer.io/docs/api/app/#section/Overview). ## Authorize Connection to Customer.io ### In Customer.io To authorize your Customer.io account, you will need an **API key** (= API token). 1. Log in to your Customer.io account as an **admin or workspace manager**. 2. Navigate to **Settings** and continue to **Account Settings**. 3. In the **API Credentials** section, switch to the **App API Keys** tab. 4. Click on **Create App API Key** and copy the generated API key. ### In Dataddo 1. On the **Authorizers** page, click on [Authorize New Service](https://app.dataddo.com/service/new) and select Customerio. 2. Fill in the Customer.io **API key** and select **your region**. 3. Rename your ***authorizer*** for easier identification and click on **Save**. ## Authorization Provide your App **API Key** and **label** it. The label can be anything you will easily recognize and remember. You can find all of your API authentication information in your Customer.io *Account Settings*. The Tracking API uses HTTP basic authorization. The App API uses bearer authorization, and you can generate tokens supporting different scopes. ## How to Create a Customer.io 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. ## 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.
