In order to use Flowdock's REST API, you will need to get your personal API Token. You will use this token to authenticate your API calls with Flowdock. To get your perosnal API Token go to:
https://www.flowdock.com/account/tokens and copy the value of the API Token.
You will need to know the
<Org Name> and
<Flow Name> where you'd like to post your message. These will be concatenated into the final destination string you post your message to.
Here is an example of a simple text message issued using the API. Note the
JSON type must be specified for the data format of your message:
<Please see attached file for image>

<Please see attached file for image>

A successful result will have a '
201 Created' return code as well as
UUID value unique to your message:
<Please see attached file for image>

And this is how it looks like when back in Flowdock and look at the flow:
