SparkPost discontinuing their Messaging Events API
I received an email from SparkPost today, including this:
This is an operational notice that we are discontinuing the Message Events API on October 1, 2019. Starting on October 1, all API calls made to SparkPost must use the Events API. You are receiving this email because our data shows that the Message Events API is currently being used by your account.
They have support for migrating node.js and python but nothing for PHP. Just creating issue to find out what your plans are for dealing with this. We haven't been ecstatic about SparkPost, so would consider moving to a different service if you're not going to maintain this.
