How to Sync to Manually
Step 1: Access CallRail API
Begin by accessing the CallRail API to retrieve your data. You will need to set up an API key from the CallRail dashboard. Navigate to the "API Keys" section under "Account Settings" to generate a key. This key will allow you to authenticate API requests for data extraction.
Step 2: Fetch Data from CallRail
Using a tool like Python's `requests` library or any HTTP client you prefer, make GET requests to the CallRail API endpoints. For example, you can fetch call logs using the `/v3/a/{account_id}/calls.json` endpoint. Ensure your requests include the necessary headers, such as `Authorization: Token token="your_api_key"`, to authenticate successfully.
Step 3: Transform Data to ClickHouse Format
Once you've fetched the data from CallRail, you need to transform it into a format compatible with ClickHouse. Convert the JSON data into a CSV or TSV format, which ClickHouse supports natively. You can use a script to parse the JSON data and write it to a CSV file, ensuring that your data types and structures match the schema you plan to use in ClickHouse.
Step 4: Prepare ClickHouse Table Schema
Before importing data into ClickHouse, create a table with a schema that matches your transformed data. Use ClickHouse's `CREATE TABLE` command to define the table structure. Ensure the column data types in ClickHouse are compatible with the data you transformed from CallRail.
Step 5: Transfer Data to ClickHouse Server
Transfer your CSV or TSV file to the server where ClickHouse is installed. You can use secure file transfer tools like SCP or SFTP to upload the file to the server. Ensure you have the necessary permissions to write files to the server location where ClickHouse can access them.
Step 6: Load Data into ClickHouse
Use ClickHouse's `clickhouse-client` command-line tool to load the data into your table. Execute a command like `clickhouse-client --query="INSERT INTO your_table FORMAT CSV" < /path/to/your/file.csv`. This command will read your CSV file and insert the data into the specified ClickHouse table.
Step 7: Verify Data Integrity
After loading the data, verify that the import was successful and that the data integrity is maintained. Run queries against your ClickHouse table to check for data completeness and accuracy. Compare a sample of the data in ClickHouse with the original data from CallRail to ensure consistency.
By following these steps, you can effectively move data from CallRail to a ClickHouse warehouse without relying on third-party connectors or integrations.
