OLS InComm Gateway's REST API allows developers to build applications that accept payemnts, such as: e-commerce web sites, shopping carts, and mobile applications and Point-of-Sale (‘POS’) systems.
Batches are groups of transactions that have not been settled yet. OLS InComm Gateway has only one open batch at a time. Through the batches resource, you can retrieve and close the currently open batch, and view lists of batches in your history.
When a transaction request is sent to OLS InComm Gateway, this authenticates the merchant by validating the API Key, performs validation of the transaction data, and forwards the transaction request for authorization by the card issuer.
OLS InComm Gateway will return a response message back with the result of the transaction.
