In this newsletter, I cover API World presentations from Irakli Nadareishvili and Christian Posta. I also suggest a deep read of Kristopher Sandoval's safety and idempotence piece; a thorough coverage of some core REST principles. There's also an API Labeling proposal by Erik Wilde and Cesare Pautasso that gives pause.

Finally, I end with yet another Grindr's API security problem.
