BIP: 72
|
|
Title: bitcoin: uri extensions for Payment Protocol
|

==Abstract==
|
|
|
|
This BIP describes an extension to the bitcoin: URI scheme (BIP 21) to
|
|
support the payment protocol (BIP 70).
|
|
|
|
==Motivation==
|
|
|
|
Allow users to click on a link in a web page or email to initiate the
|
|
payment protocol, while being backwards-compatible with existing
|
|
bitcoin wallets.
|
|
|
|
==Specification==
|
|
|
|
The bitcoin: URI scheme is extended with an additional, optional
|
|
"r" parameter, whose value is a URL from which a PaymentRequest
|
|
message should be fetched (characters not allowed within the scope
|
|
of a query parameter must be percent-encoded as described in RFC 3986
|
|
and bip-0021).
|
|
|
|
If the "r" parameter is provided and backwards compatibility
|
|
is not required, then the bitcoin address portion of the URI may be
|
|
omitted (the URI will be of the form: bitcoin:?r=... ).
|
|
|
|
When Bitcoin wallet software that supports this BIP receives a
|
|
bitcoin: URI with a request parameter, it should ignore the bitcoin
|
|
address/amount/label/message in the URI and instead fetch a
|
|
PaymentRequest message and then follow the payment protocol, as
|
|
described in BIP 70.
|
|
|
|
Bitcoin wallets must support fetching PaymentRequests via http and
|
|
https protocols; they may support other protocols. Wallets must
|
|
include an "Accept" HTTP header in HTTP(s) requests (as defined
|
|
in RFC 2616):
|
|
|
|
<pre>Accept: application/bitcoin-paymentrequest</pre>
|
|
|
|
If a PaymentRequest cannot be obtained (perhaps the server is
|
|
unavailable), then the customer should be informed that the merchant's
|
|
payment processing system is unavailable. In the case of an HTTP
|
|
request, status codes which are neither success nor error (such as
|
|
redirect) should be handled as outlined in RFC 2616.
|
|
|
|
==Compatibility==
|
|
|
|
Wallet software that does not support this BIP will simply ignore the
|
|
r parameter and will initiate a payment to bitcoin address.
|
|
|
|
==Examples==
|
|
A backwards-compatible request:
|
|
<pre>
|
|
bitcoin:mq7se9wy2egettFxPbmn99cK8v5AFq55Lx?amount=0.11&r=https://merchant.com/pay.php?h%3D2a8628fc2fbe
|
|
</pre>
|
|
Non-backwards-compatible equivalent:
|
|
<pre>
|
|
bitcoin:?r=https://merchant.com/pay.php?h%3D2a8628fc2fbe
|
|
</pre>
