Right now we have a working VBA code that sends some HTTP POST commands (API for third party program). This process takes up to a second to complete. This is not fast and accurate enough. We need code that accomplishes fast and time-accurate sending of HTTP POST command where the specific HTTP POST can be pre-prepared as we did in Excel, and can be programmed to run at a specific time with sub-second time accuracy.

I have just completed a VBA To API project using Toggl and I also run my own VBA get and POST processes via PHP and Python to access the Xero API. I am happy to recode your calls into PHP or Python but would strongly suggest I have a careful review of your VBA code first. Timing issues may come from your local network or firewall or the setup of your PC. There is no inherent reason for a VBA HTTP POST to be slow. Happy to discuss. I do not quote silly deadlines. This sounds interesting and I'd be happy to work on it for you Mark

Hello I have done HTTP client/server tasks in plain C and know the protocol well. One of them was a domain catching script, which I translated from PHP. I can even add threads, if you want to have asynchronous message sending. Thanks.

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 6 years. My work is online game developing, and mainly focus on server side, using c++ under linux environment. I used c++ to make many great projects, for example, I made the tools which can convert java files into c++ scripts, of course garbage collection included, this job is very similar to a compiler, and is very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.
