SMS API

SMS API Descriptions
Plum offers four services for its SMS REST API:
Method
Service
Description
​POST​
​sms/queue​
​Queues an SMS message and returns an SMS message resource​
​GET​
​sms/status​
​Returns a single SMS message resource​
​GET​
​sms/messages​
​Returns a filtered list of SMS message resources​
​GET​
​sms/conversation​
​Returns SMS messages exchanged between two defined phone numbers​
Please note that each of these SMS REST APIs use HTTP AUTH for authentication. The username/password to be used for authentication are the same as your standard Plum DEV login credentials.
All of the SMS REST APIs have the same return format that includes a status (success or failure), error message and the result data.
