Answer 1

to use the api of the sms mailing services
, in general, it all comes down to sending a request to the api of the service, with it it is transmitted what to send, to whom to send, and some kind of token. Sending from js is not a good idea, since your token can be stolen corny. So usually js sends to the server, let's say php sends a request to api via curl. Some services provide php sdk and then you generally solve everything in two lines. So the first thing to do is select a service and read its documentation.
