400 ERROR - Bad Request

Hello,

I am trying to upload a PDF document to a REST api - sandbox as mentioned here https://apimarketplace.uhcprovider.com/ ... attachment

it works in SoapUI and using python on iSeries. However, I am getting Bad Request when I am consuming using HTTPAPI.

Here is the debug log:

I'm not familiar with this API, but... you are telling it that the data is in multipart/form-data format, but you aren't encoding it in that format -- you're just sending the raw PDF.

Does the API expect it in that format? If so, use the multipart form-data encoder in HTTPAPI to encode it.

Or, does the API expect the raw PDF? If so, change the content-type to application/pdf or whatever makes sense.

Thank you for the quick response Scott. Trying to figure. API documentation/swagger is not clear on that. When I run from python, I see this

Yeah, the data is encoded as multipart/form-data. (Though, it's sending a content-type of text/plain which is weird -- but maybe the server accepts it.)

Use HTTPAPI's multipart/form-data encoder.

Please remove this line from your code:

Code: Select all

Accept-Encoding:gzip,deflate'   + CRLF
HTTPAPI does not support gzip or deflate encoding, so if you add something like that and communicate with a server that supports it, your data will come back compressed, and you won't be able to read it. Unless you're planning to write your own code to support that?
