Grinding through tedious and painstaking parts of an application.

I’m working on integrating an in-house system to an ITSM SaaS product for incident management and tracking. I have had nothing but hair-ripping issues with their API, it’s over-the-top complexity seemingly just for complexity’s sake, odd undocumented gotchas that it’s been taking said SaaS provider days to reply with an answer on, and just overall tedium around implementing it. I dread working on it despite normally being a power-through, get things done type of person. It takes so much boiler plate to make the simplest calls and often half a dozen calls or more just to get required info to do simple tasks like assigning an incident or creating a comment on an incident. Needless to say I have next to no drive to hammer it out, but it’s just got to get done.

Does anyone encounter this? Is all there is to it just to bite the bullet and hammer it out? Anyone have suggestions to keep on keeping on track and getting it done without feeling like I need a frontal lobotomy every time I get off work for the day?
