Features

Simple interface
Uniform plain old objects are returned by all official libraries, so you don't have to serialize/deserialize the JSON returned by our API.

Documentation

Given you have all the requirements above, you will now be able to authenticate and communicate effectively with our API using this library.

The next section will show the various actions that can be performed by you, the merchant.

Poll Transaction Status

Poll the status of a transaction given a valid request_id

Note: The request_id in this context is essentially the transaction_id of an existing request.

# Using a env variable token
request = vpos.get_request(request_id: '29fTRtkFaf8cQklRuHTvGDaecj5')
# Or using a explicitly stated token
request = vpos.get_request(request_id: '29fTRtkFaf8cQklRuHTvGDaecj5', token: 'EbRTIbb1jHbXEbRTIbbwaoJ6w06nLcRG7X')
# {:status_code=>303, :message=>"ACCEPTED", :location=>"/api/v1/transactions/29fTRtkFaf8cQklRuHTvGDaecj5"}

request_id = vpos.get_request_id(request)
# "29fTRtkFaf8cQklRuHTvGDaecj5"

transaction = vpos.get_transaction(transaction_id: "29fTRtkFaf8cQklRuHTvGDaecj5")
# {
#   :status_code=>200,
#   :message=>"OK",
#   :data=> {
#      :amount=>"1.23",
#      :clearing_period=>156,
#      :id=>"29fTRtkFaf8cQklRuHTvGDaecj5",
#      :mobile=>nil,
#      :parent_transaction_id=>29fTRtkFaf8cQklRuHTvGDaecj4,
#      :pos_id=>nil,
#      :status=>"accepted",
#      :status_datetime=>"2022-05-25T18:25:39Z",
#      :status_reason=>nil,
#      :type=>"refund"
#    }
# }

Argument	Description	Type	Required?
`request_id`	The ID of transaction you wish to poll	`string`	Yes
`token`	Merchant token generated at vPOS merchant portal	`string`	No (if set as env variable)
