Welcome to Coinbase Onramp. Get up and running in less than 5 minutes.

​
Step 1: Sign up for a CDP account

If you already have a Coinbase account, you can just Sign in.

​
Step 2: Verify your email

Enter your email address and verify with a code sent to you immediately after signup. Set up 2-factor authentication (2FA) with your phone number.

​
Step 3: Get your Project ID

A default project name displays (you can rename this). Copy your Project ID to use later (this is referred to as appId).

​
Step 4: Create a Secret API Key

Navigate to the API Keys tab. Create and download your API key. Enter an API key nickname (restrictions are optional).

Secure your private/public key pair in a safe location.

​
Install CDP CLI tools

Install cdpcurl to make test API calls. cdpcurl allows you to make authenticated HTTP requests to the Coinbase API with your API key.

​
Integrate Coinbase Onramp and Offramp into your product

Coinbase’s fiat-to-crypto (Onramp) and crypto-to-fiat (Offramp) APIs and SDKs offer a lightweight way for Apps to generate URLs to Coinbase’s hosted widgets.

Developers can use the REST API to interact with Coinbase Onramp and Offramp.

In addition, we recommend generating a One-click-buy URL via API for most developers!
