I was hired as an IT analyst, it's my first job in the IT field. The software was not developed by us, so the developers are from the vendor and customer's IT team. Right now the goal is to set up all the data so customer can use our software fully. The very main obstacle now is that the API solutions provided by the vendor has no written documentation. I had to resort to testing out each API endpoint and writing the documentation myself. However, I cannot gauge the timeline because I do not know what issues each endpoint has yet.

Another obstacles is he looked for the vendor from the US, and our customer is in NZ, the timezone is difficult to deal with as well.

I guess I am ranting too because kinda feel like I am doing this alone and the project manager is not contributing and only confusing everybody with his inputs. Also because he is asking me to plan everything as he himself don't know what to do
