Exchanging Data
protel uses protel I/O to route incoming and outbound data messages. Messages can be delivered to protel I/O from an HTTPS endpoint. protel I/O provides different endpoints for synchronous and asynchronous SOAP 1.2 messages to accommodate WSDL requirements. protel I/O is using the Version 'OTA 2011A' for the OTA messages.
Security, Access, and Authentication
Security is important to you and protel. All messages must be authenticated using protel IO’s secure authentication processes. To ensure the source of messages are valid, all messages flowing to and from protel are checked. Messages are verified by protel I/O. Access to the API is only permitted through SSL (secure sockets layer). For HTNG messaging, all messages will utilize the HTNG 1.2 SOAP header.
Authentication of Inbound messages
Direction Vendor to protel. All messages require a protel provided Bearer Token (whether RQ or RS!).
The Authentication token must be submitted in HTTP headers.
Protel will provide you with your bearer token at the time we commence testing. When requesting a test environment protel will provide you with a token at that time.
Format of HTTP Headers
In order to process your incoming requests, all of your messages must contain headers inside the HTTP headers

| Envelope / Header / CorrelationID | http://htng.org/PWSWG/2007/02/AsyncHeaders | The CorrelationID of the message you are sending to identify the transaction (HTNG namespace) | Mandatory |
| Envelope / Header / Target | http://protel.io/soap | The desired target service name of the message - ONLY for SYNC messages | Optional |
| Envelope / Body | http://www.w3.org/2003/05/soap-envelope | The HTNG/OTA/IO message | Mandatory |

Format of the Acknowledgment (ASYNC communication)
To communicate with an ASYNC pattern, the receiver of the message needs to send an ACK with the HTTP status code 200 and the following payload back to the sender before the receiver starts the processing of the message.
The Content-Type needs to be added in the HTTP Header with the value "application/soap+xml".
<?xml version='1.0' encoding='UTF-8'?> <env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope"> <env:Header> <htnga:CorrelationID xmlns:htnga="http://htng.org/PWSWG/2007/02/AsyncHeaders">RES#045627#CREATE#000002#1575294717780#6244XXX</htnga:CorrelationID> <htnga:RelatesToCorrelationID xmlns:htnga="http://htng.org/PWSWG/2007/02/AsyncHeaders">RES#045627#CREATE#000002#1575294717780#6244XXX</htnga:RelatesToCorrelationID> </env:Header> <env:Body> <ns:HTNG_AcknowledgeReceipt xmlns:ns="http://htng.org/2014B"/> </env:Body> </env:Envelope>

Circular Message Flow
The circular message flow prevents a message loop between Integration Partner and Protel.
It is applicable for message types which the PMS accepts in both directions In/Out (e.g. OTA_ProfileModifyRQ, OTA_HotelResNotifRQ, etc.)
Sample:
The Integration Partner sends an OTA_ProfileModifyRQ message to Protel. This profile is modified in the PMS and then sent again as OTA_ProfileModifyRQ by the PMS. The Integration Partner will also modify the profile again and send it back to Protel, thus creating an endless loop.
To stop this endless loop, we have implemented the "Caused-By CorrelationID". The "Caused-By CorrelationID" is automatically added to the outbound messages by the PMS if a modification has been made due to an inbound message. Based on the "Caused-By CorrelationID", our ESB knows to which Ontegration Partner the message does not have to be sent.
