Thanks for the super clear guidelines - as always very well explained. I was able to get PESOS from Pocket and Feedly working through IFTTT as well on my Known CMS site. IFTTT is sending POST requests to my micropub endpoint and Known is happily accepting the accesstoken, yet when I see the response of the action in IFTTT it always says "Failed". I've checked the response with POSTMAN and Known is responding with a status code 200 - as it should? - so it's okay for now, as it works; but was wondering why IFTTT is flagging the actions as failed?
