Flattr Developer Platform


Flattr was founded by developers and hackers and we know that your apps and hacks with our API will only help to promote more use of Flattr in supporting content creators. We hope that common sense and good faith will make up the basis for a great ecosystem and therefore we try to keep the list of API rules as short as possible.

However, we reserve the right to change these policies and/or terminate your API access at any time if we find it necessary for protecting our users', partners', and own rights.

Current policies for using the Flattr API:
