Overview

The following methods can be used to authenticate your requests to the Coinbase Developer Platform (CDP). Choose the method that best suits your needs:

Method	Difficulty	Description
Use an Axios request client	Easy	Use an Axios client with a pre-configured interceptor that automatically handles authentication for all requests.
Generate your authorization headers	Intermediate	Generate authentication headers and apply them to your preferred HTTP client.
Generate a JWT	Advanced	Generate a JWT token, manually create your authentication headers, and apply them to your preferred HTTP client.

Visit the CDP Authentication docs for more details.

Generate a JWT

The following example shows how to generate a JWT token, which can then be injected manually into your Authorization header to authenticate REST API requests to the CDP APIs using the HTTP request library of your choice. Step 1: Install the required package:

npm install @coinbase/cdp-sdk

Step 2: Generate a JWT:

import { generateJwt } from "@coinbase/cdp-sdk/auth";

// For REST (HTTP) requests
const jwt = await generateJwt({
  apiKeyId: "YOUR_API_KEY_ID",
  apiKeySecret: "YOUR_API_KEY_SECRET",
  requestMethod: "GET",
  requestHost: "api.cdp.coinbase.com",
  requestPath: "/platform/v2/evm/accounts",
  expiresIn: 120, // optional (defaults to 120 seconds)
});

console.log(jwt);

// For websocket connections
const websocketJwt = await generateJwt({
  apiKeyId: "YOUR_API_KEY_ID",
  apiKeySecret: "YOUR_API_KEY_SECRET",
  requestMethod: null,
  requestHost: null,
  requestPath: null,
  expiresIn: 120, // optional (defaults to 120 seconds)
});

console.log(websocketJwt);

For information about the above parameters, please refer to the Authentication parameters section. Step 3: Use your JWT (Bearer token) in the Authorization header of your HTTP request:

curl -L 'https://api.cdp.coinbase.com/platform/v2/evm/accounts' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -H 'Authorization: Bearer $jwt'

Generate your authorization headers

The following example shows how to generate the required authentication headers for authenticating a request to the CDP REST APIs, using the HTTP request library of your choice. Step 1: Install the required package:

npm install @coinbase/cdp-sdk

Step 2: Generate authorization headers:

import { getAuthHeaders } from "@coinbase/cdp-sdk/auth";

const headers = await getAuthHeaders({
  apiKeyId: "YOUR_API_KEY_ID",
  apiKeySecret: "YOUR_API_KEY_SECRET",
  walletSecret: "YOUR_WALLET_SECRET",
  requestMethod: "POST",
  requestHost: "api.cdp.coinbase.com",
  requestPath: "/platform/v2/evm/accounts",
  requestBody: {
    name: "MyAccount",
  },
  expiresIn: 120, // optional (defaults to 120 seconds)
});

console.log(headers);

For information about the above parameters, please refer to the Authentication parameters section.

Use an Axios request interceptor

Step 1: Install the required packages:

npm install @coinbase/cdp-sdk axios

Step 2: Create an authenticated Axios client: The following example shows how to use an Axios HTTP client with a pre-configured interceptor to authenticate your requests to the CDP REST APIs. This client will automatically add the appropriate authentication headers to each request.

import axios from "axios";
import { axiosHooks } from "@coinbase/cdp-sdk/auth";

// Create an Axios instance
const axiosClient = axios.create({
  baseURL: "https://api.cdp.coinbase.com",
});

// Add authentication to the client
axiosHooks.withAuth(axiosClient, {
  apiKeyId: "YOUR_API_KEY_ID",
  apiKeySecret: "YOUR_API_KEY_SECRET",
  walletSecret: "YOUR_WALLET_SECRET",
});

// Make authenticated requests (example)
// The appropriate authentication headers will be automatically added to the request
try {
  const response = await axiosClient.post("/platform/v2/evm/accounts", {
    name: "MyAccount",
  });
  console.log(response.data);
} catch (error) {
  console.error("Request failed:", error);
}

The Axios interceptor will automatically:

Generate a JWT for each request
Add the JWT to the Authorization header
Set the appropriate Content-Type header
Add wallet authentication when required

For information about the above parameters, please refer to the Authentication parameters section.

Authentication parameters

The following table provides more context of many of the authentication parameters used in the examples above:

Parameter	Required	Description
`apiKeyId`	true	The unique identifier for your API key. Supported formats are: - `xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx` - `organizations/{orgId}/apiKeys/{keyId}`
`apiKeySecret`	true	Your API key secret. Supported formats are: - Edwards key (Ed25519): `xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx==` - Elliptic Curve key (ES256): `-----BEGIN EC PRIVATE KEY-----\n...\n...\n...==\n-----END EC PRIVATE KEY-----\n`
`requestMethod`	true*	The HTTP method for the API request you’re authenticating (ie, `GET`, `POST`, `PUT`, `DELETE`). Can be `null` for JWTs intended for websocket connections.
`requestHost`	true*	The API host you’re calling (ie, `api.cdp.coinbase.com`). Can be `null` for JWTs intended for websocket connections.
`requestPath`	true*	The path of the specific API endpoint you’re calling (ie, `/platform/v1/wallets`). Can be `null` for JWTs intended for websocket connections.
`requestBody`	false	Optional request body data.
`expiresIn`	false	The JWT expiration time in seconds. After this time, the JWT will no longer be valid, and a new one must be generated. Defaults to `120` (ie, 2 minutes) if not specified.

* Either all three request parameters (requestMethod, requestHost, and requestPath) must be provided for REST API requests, or all three must be null for JWTs intended for websocket connections.
