Hello @mamata.nivalkar SSL does not support ‘AT+CIPSENDBUF’. Could you try using ‘AT+CIPSEND’ instead of ‘AT+CIPSENDBUF’? image957×1029 40.6 KB

Hello @austin Thanks for your reply. I have tried using ‘AT+CIPSEND’ and it is working as expected for HTTP GET request. Now, I am trying HTTP POST request. I need to connect to graph.facebook.com with https. Then using whatsapp api, need to send message. Following is the sequence Wiznet360_HTTP post issue1366×728 49.3 KB But getting 408 in response. Can you please give an example of HTTP POST? Thanks, Mamata

@mamata.nivalkar After testing using a program called Postman, How about applying it to WizFi360?

@austin Thanks for your reply. I checked using Postman utility. It is working as expected. Compared data. Content-Length parameter found to be wrong. Corrected it. Now I am able to hit whatsapp api using WizFi360 also. Thanks for you support.
