BTC Postage Link Builder
This tool allows you to generate a URL that prefills all or part of a new label form. The simplest way to generate a prefill URL is to use our prefill link builder tool. Developers who want to generate BTC Postage URLs within their applications can refer to the following available prefill options.
Prefill links should use this base URL (https://btcpostage.com/?) and all params should be appended to the URL. All parameters are optional and are used to prefill a user-editable label form. No API key is required.
