To be able to connect the SMPP API, the following are required for authentication:
Only one binding is allowed for a given API Identifier. However based upon some rules on the API account you may be allowed to bind more than once using the same API public key. You can bind as:
Transceiver: Send and receive messages to and from the SMPP API connection over a single SMPP session.
Transmitter: Send short messages to the SMPP API and receive responses.
Receiver: Receive delivery receipts of short messages from the API.
The data encoding supported by the Hubtel SMPP API are data-coding: 0 (for ISO8859-1 encoding) and data-coding: 3 (for GSM0338 encoding).
