Currently we provide API tokens based on your user account per project. You can retrieve a token of a certain project by visiting the project and by replacing the last part of the URL with "api_token" like this:
Our API is built using Google Cloud Endpoints. This means that you can also use one of the Client Libraries designed for Google APIs.
They are available for any major platform/language: https://developers.google.com/api-client-library/
To get familiar with our API you can check out our interactive documentation here:
Using your API token and the project ID you can actually make requests to our API right from within the documentation.
I hope this was a bit helpful to you. Feel free to reach out anytime. We can't wait to see what you're building.
If you have any feedback on endpoints that you would like to use or how we could improve the API please let us know :) firstname.lastname@example.org
