Getting Started

Trigger a workflow on BigQuery - Query Results with Google Cloud API. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

  1. Configure the BigQuery - Query Results trigger
    1. Connect your Google Cloud account
    2. Configure Polling interval
    3. Configure Event Size
    4. Select a Dataset
    5. Configure SQL Query
    6. Optional- Configure De-duplication Key
  2. Add steps to connect to + APIs using code and no-code building blocks
  3. Deploy the workflow
  4. Send a test event to validate your setup
  5. Turn on the trigger

Authentication

Google Cloud uses API keys for authentication. When you connect your Google Cloud account, Pipedream securely stores the keys so you can easily authenticate to Google Cloud APIs in both code and no-code steps.

When you create a service account in GCP, you'll be asked to generate a service account key. Create that key and download the key details in JSON format.

Open the key JSON in a text editor, then copy and paste its contents here.

Stop writing boilerplate code, struggling with authentication and managing infrastructure. Start connecting APIs with code-level control when you need it — and no code when you don't.
