BG95 - SSL with QHTTPPOST

Hey All

Was hoping to get clarification on a simple point:

When attempting an POST Request via the BG95, when I send the actual QHTTPPOST command I get just a message “ERROR” (not CME) in return –

I’ve proven this almost exact exchange with our HTTPS server doing a GET request, but thought perhaps the BG95 assumes a certificate is need for a POST? (which should be disabled with that “seclevel”,1,0 but i wasn’t sure if that was a requirement for POST)

Resolved:

The URL string needed to have it’s URL suffix i.e. https://www.ourexampleurl.com/sendPOSThere

I found this to be counter intuitive as it was not need for the GET request, and everything could just be set in the header

Great !

I attached one example for Http post without certicates.
