In october, Pizzly teams up with Hacktoberfest 2020 to increase the number of API integrations to up to 100 APIs 🎉 To learn more about how to participate and win, look at our Hacktoberfest guide.

Coinbase has been identified as a major API that we would love to support. Your mission is to create a configuration file that make this API ready to be used by Pizzly developers.

Here are a few links to help you achieve this task:

• Coinbase official website

If you are interested in adding this integration to Pizzly, please comment below first, to tell other contributors that you're on it.

Once you've the configuration ready, please create a PR that links to this issue (more detail in our Hacktoberfest guide). Here's an example of a similar PR that was recently accepted.
