Coinbase integration allows you to sync your cryptocurrency accounts, track holdings, and monitor transactions directly in Sure using the Coinbase Developer Platform (CDP) API.
This integration is currently in beta. Please report any issues you encounter.

​
How it works

When you connect your Coinbase account, Sure syncs:
  • Account balances across multiple cryptocurrencies
  • Trading history and transactions
  • Holdings with real-time valuations
  • Native currency support (USD, EUR, GBP, etc.)
The integration supports both cryptocurrency balances and fiat currency accounts linked to your Coinbase profile.

​
Prerequisites

To use the Coinbase integration, you need:
  • An active Coinbase account
  • Coinbase CDP API credentials (API key and API secret)

​
Getting your API credentials

  1. Log in to your Coinbase CDP portal
  2. Navigate to Settings → API
  3. Create a new API key with the following permissions:
    • View account information
    • View transaction history
    • View balances
  4. Save your API key and API secret securely
Your API secret is only shown once. Store it securely - you’ll need both the API key and secret to connect Sure.

​
Connecting Coinbase to Sure

  1. Navigate to Settings > Providers in Sure
  2. Click Add Provider and select Coinbase
  3. Enter your API credentials:
    • API Key: Your Coinbase API key
    • API Secret: Your Coinbase API secret
  4. Click Connect

​
Account linking

After connecting, Sure will discover all your Coinbase accounts. You’ll need to link each Coinbase account to a Sure account:
  1. Review the list of discovered Coinbase accounts
  2. For each account you want to track:
    • Select an existing Sure account, or
    • Create a new account to link it to
  3. Click Save to complete the linking
