Nemo web services payment integration for mobile apps

Available web-services

Before sending payment transactions, you have to create a successfull booking. Order should have the "booked" status. After that, you can proceed to the payment. There are three web services used in payment process:

• Payment initialization

WSDL address: http://CLIENT_DOMAIN/wsdev/wsdl.php?version=1.0&for=PaymentInitialization

Documentation: Getting list of allowed payment gateways

• Selecting a payment method

WSDL address: http://CLIENT_DOMAIN/wsdev/wsdl.php?version=1.0&for=SelectPayment

Documentation: Selecting a payment method

• Order updating

WSDL address: http://CLIENT_DOMAIN/nemoflights/wsdl.php?version=1.0&for=UpdateBook

Documentation: Order updating

Payment workflow

Below is the scheme of payment workflow.

Description of the background order synchronization

There are two situations when this process should be run:

• Due to some reasons (lost internet connection, etc.) user was not redirected to UrlToCatch.
• Payment status of the order was not delivered yet from payment gateway to Nemo system and the additional one is required in a few seconds or minutes.

Order synchronization is periodically sending UpdateBook request to get actual common and payment statuses.

! Warning! Do not send this request very often. No more than one request per 3 minutes. Also do not send it infinitely while you do not get PaymentStatus=”fully_paid” and Status=”ticket”. Limit the total number of synchronization requests to some value. There is a recommendation for periods of synchronization. Firstly send synchronization request 5 times for every 3 minutes. Then send request 6 times for every 10 minutes. If successfull statuses were not retrieved, you should terminate synchronization.
