BulkSMS provides a number of APIs to allow developers to integrate functionality into their systems.


JSON

Our REST API uses JSON for requests and responses. This is the API we recommend for all new integration work.


EAPI

Our legacy HTTP API (deprecated) is based on form encoded requests and text responses.


SMPP

SMPP is a standard within the mobile industry. If you’re integrating an existing application which has support for SMPP and you are expecting to send high volumes, this may be a good choice.
