CoinMarketCap is a cryptocurrency tracking platform. In this guide, we’ll walk through how to pull cryptocurrency data from the CoinMarketCap API directly into Google Sheets, using the API Connector add-on. We'll first get an API key from CoinMarketCap, and then set up a request to pull in cryptocurrency exchange rate details to your spreadsheet.

• Part 1: Get your CoinMarketCap API Key
• Part 2: Create your API Request URL
• Part 3: Enter values into API Connector
• Part 4: CoinMarketCap API Notes and Expansions

PART 1: GET YOUR COINMARKETCAP API KEY

1. If you haven't already, navigate to https://coinmarketcap.com/api/ and click Get Your API Key Now
   
2. Fill out your details and click Create My Account
   
3. A moment later you'll receive an email. Click on the email to verify your account, and you'll be redirected into your new CoinMarketCap dashboard. Congrats! You now have access to the CoinMarketCap API. Hover over the API Key box in the top left and copy the key to your clipboard.
   

PART 2: CREATE YOUR API REQUEST URL

We’ll follow the CoinMarketCap documentation to access the latest crypto quotes.

• API root: https://pro-api.coinmarketcap.com
• Endpoint: /v1/cryptocurrency/listings/latest

Putting it together, we get the full API Request URL:

https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest

PART 3: ENTER YOUR VALUES INTO API CONNECTOR

We can now enter all our values into API Connector and import CoinMarketCap API data into Google Sheets.

1. Open up Google Sheets and click Add-ons > API Connector > Create New API Request.
2. In the Create Request interface, enter the Request URL we just created
   

3. Under Headers enter two sets of key-value pairs like this:
   

   X-CMC_PRO_API_KEY	{API Key}
   Accept	application/json

   Replace {Api Key} with the value provided above in step 3.
   

4. Create a new tab. You can call it whatever you like, but here we'll call it 'CoinMarketCap_Latest'. While still in that tab, click 'Set' to use that tab as your data destination.
5. Name your request. Again we'll call it 'CoinMarketCap_Latest'
6. Click Run and a moment later you’ll see the latest market data for all active cryptocurrencies in your Google Sheet:
   

PART 4: COINMARKETCAP API + GOOGLE SHEETS NOTES AND EXPANSIONS

1. Experiment with endpoints and query strings as described in the documentation to see other types of cryptocurrency data. For example, this URL will retrieve the latest global cryptocurrency market metrics:

   https://pro-api.coinmarketcap.com/v1/global-metrics/quotes/latest

2. The free version of CoinMarketCap limits the number of accessible endpoints and number of call credits. Check the pricing page for details.
3. If you're looking for a more dynamic, ticker-like experience in Sheets, check out the API Connector custom function IMPORTAPI() for faster refresh rates.
