Re: Walmart Marketplace API

I take it back, HTTPS is shown in the original post...but not that latter
one..

SetError() #49: SSL_protocol: Unknown protocol 5000
Protocol Used:
http_persist_req(POST) entered.
http_long_ParseURL(): entered
http_long_ParseURL(): entered
do_oper(POST): entered

Error 49 is I think..
     D GSKKM_ERROR_VALIDATION_KEY_PRIVATE_KEY_USAGE_PERIOD...
     D                 C                   CONST(49)

Might try turning off the validation
https_strict(*OFF);

HTH,
Charles
