The API and associated documentation is perhaps the worst I have ever seen in my many years of development. Lack of logic, inconsistencies galore, poorly written, poor structured, the list goes on. It has been a head-scratching minefield to work with, and there are endpoints that still only work in sandbox not live.
To top it off, the HMRC Software Development Support Team, are extremely slow to respond to anything. More than a week to get this response: "Thank you for reaching out. I wanted to extend my apologies for any inconvenience this might cause. We are currently navigating through a substantial volume of queries. Rest assured, we are doing our utmost to respond to everyone as swiftly as possible. Your patience and understanding are greatly appreciated, and we will get back to you as soon as we can."
And to top that off, getting approval for software takes months. We applied for production credentials end of January, and here we are end of March and still nothing!
I was upbeat months ago about MTD for Income Tax (perhaps the only person to feel that way), but now, not at all.
Heads should definitely role somewhere in HMRC for this madness.
Problem is, in time those in charge will probably be rewarded with lucrative gigs elsewhere....Sir Keir/Labour this is happening on your watch. Wilfred Frost had MP Murray on his show....how about a question....'how is MTD4IT going?'
I also wonder how the budget is spiralling.
