Could you try removing the PS_DOC_PMT portion and seeing how that impacts your result? Also I've edit out your APIKey and Authorization header as those shouldn't be posted online.

Hi MikeRitchie,

We have removed PS_DOC_PMT portion. But we are facing same issue. Can you send me working request data. So we can try at our end.

Thank you.

Hi Team,

Please provide us solution for this problem. It's blocker for us for our integration.

Thank you.

Is anyone helping with this issue. I'm having same issue. Also, one thing I was thinking does the payload need to be encrypted first or encoded? I'm just using curl to test so not sure if it is encoding it? I hope...

For my own project, I had to make sure that the PS_DOC_HDR section had the CUST_NO field added to it with a valid customer number from CounterPoint. I ran into that same 500 error and was only able to resolve it once I had added a valid CP customer number.

As for encryption, I did not need anything beyond generating a certificate that I installed on the client machines where my application would be run from.

@asgarh So here is my own experience with adding Document...i.e. create an order / ticket. Hope this might help some people. If your getting IEnumerable exception error. Most likely you are not encoding the json or your not putting in the .ContentType = "application/json" header part. This basically will make the body misaligned hense the reason your getting array errors. Once your past these errors and getting errors like referencing a field name then you know your past the content part. Most of the errors past this had to do with tax and making sure all my calculations were correct between price of product, amount of tax, taxable amount, total price. Also make sure any discounts are subtracted and you have the correct tax codes in there. Anyway, Hope that helps anyone.
