“Airbyte helped us accelerate our progress by years, compared to our competitors. We don’t need to worry about connectors and focus on creating value for our users instead of building infrastructure. That’s priceless. The time and energy saved allows us to disrupt and grow faster.”

Rupak Patel
"With Airbyte, we could just push a few buttons, allow API access, and bring all the data into Google BigQuery. By blending all the different marketing data sources, we can gain valuable insights."
How to Sync to Manually
Step 1: Set Up Google Cloud Project
First, log in to your Google Cloud Console and create a new project or select an existing one. Ensure that billing is enabled for the project, as BigQuery requires an active billing account. Navigate to the "BigQuery" section and activate the API if it is not already enabled.
Step 2: Obtain Coin API Key
Visit the Coin API website and sign up for an account if you haven't already. Once registered, navigate to the API section to generate an API key. This key will be used to authenticate your requests to the Coin API.
Step 3: Write a Python Script to Fetch Data
Create a Python script using the `requests` library to fetch data from the Coin API. Use the API key obtained in step 2 for authentication. For example:
```python
import requests
api_key = 'YOUR_COIN_API_KEY'
url = 'https://rest.coinapi.io/v1/exchangerate/BTC/USD'
headers = {'X-CoinAPI-Key': api_key}
response = requests.get(url, headers=headers)
data = response.json()
```
Step 4: Transform Data into BigQuery-Compatible Format
Process the data fetched from the Coin API into a format suitable for BigQuery. Typically, this involves converting the data into a JSON format or a CSV format. Ensure that the data types align with BigQuery's supported data types. For JSON, ensure that the structure is flat or can be easily parsed.
Step 5: Create a BigQuery Dataset and Table
In the Google Cloud Console, navigate to BigQuery. Create a new dataset if one doesn't exist by clicking on "Create dataset,"� and specify the dataset ID. Within the dataset, create a new table with the appropriate schema that matches the data you are importing.
Step 6: Use Google Cloud SDK to Upload Data
Install the Google Cloud SDK on your local machine if it's not already installed. Use the `bq` command-line tool to upload the data file. For example, if your data is in a JSON file:
```bash
bq load --source_format=NEWLINE_DELIMITED_JSON your_dataset.your_table /path/to/your/data.json
```
Ensure that the data types in your JSON file match the schema of the BigQuery table.
Step 7: Automate the Process
To automate the data fetching and uploading process, consider using a task scheduler like `cron` on Unix-based systems or Task Scheduler on Windows. Create a script that runs your Python data-fetching script and then executes the `bq load` command. Schedule it to run at regular intervals to keep your BigQuery data updated.
By following these steps, you can effectively move data from the Coin API to BigQuery without relying on third-party connectors or integrations.
