Bitcoin Postage API Documentation

Prerequisites for using our API

We provide a REST API to help you create postage labels with your application.

Before you can start using the API, you need to do the following:

Create an account
Create an API access

Authentication

Once you've registered and created your API access, you will have access to your API key and secret. These are required when making calls to the API. You can have multiple API access codes, which will allow you to manage multiple applications under the same account.

Making Requests

All requests to our API are made with POST verbs. When making requests, arguments are passed via params. If you're using one of our plugins, the requests are handled for you automatically when you call the appropriate function.
