Phone.com’s standard phone service lets you send and receive SMS/MMS messages using your Phone.com numbers. The Phone.com API extends this functionality, letting you send SMS/MMS messages from your application (through your phone number and our API server) to your users. You can also use the API to retrieve the history of SMS/MMS sent from / delivered to your account.
This service is used to send a message for extension.
This API endpoint is designated for Person to Person (P2P) communications. Improper use for marketing type purposes or Application to Person (A2P) will cause upstream cellular companies to block the “From” number for SMS use. If you plan to use this endpoint for A2P or A2A applications that might also entail high volume, i.e., above the FREE limits set by the Phone.com plan, please contact our API support team at [email protected] to discuss other options.
