Send this request from your browser to the Mursilat API.

documented example

Preview — this copy of the docs isn’t on mursilat.com, so the console shows the documented example instead of calling the API.

Real requests use your real number and plan: they can send WhatsApp messages, spend quota and delete data. (changes settings)
