RegLink APIs

July 1, 2019


Cvent Passkey’s RegLink API’s are a set of open API’s which are generally intended to provide functional integration with external applications such as registration systems.

RegLink API’s provide external systems the ability to interact and exchange data with Passkey’s event and hotel reservation-booking engines.

Generally, there are 4 primary categories of functionality which RegLink API’s support:

  1. Allow individual registrant information to be sent to Passkey to streamline the hotel reservation process for attendees. Registrants can then be directed to Passkey following their registration and reserve a hotel room without having to re-enter their personal data a second time in Passkey.
  2. Ability for an external system to fetch Passkey Event Details and hotel room availability based on a variety of criteria.
  3. Ability for an external system to fetch detailed reservation information for individual registrants.
  4. Ability for an external system to Create, Modify or Cancel a registrants’ hotel reservation directly or indirectly.

The RegLink API supports two primary communication methods: URL-based and web services (SOAP). URL-based calls utilize basic formatted URLs to communicate information to Cvent Passkey, while our web service APIs utilizes a more robust set of XML messages to send and receive data.

Most third party applications can utilize the URL-based calls, which can simplify the development effort needed to implement the solution; however, web service calls are also available if this method is needed or preferred.

There are two main types of RegLink integrations:

RegExpress and Reglink Basic – Allows a third party application to send basic attendee information to Cvent Passkey. Housing reservations are then completed through the Cvent Passkey Attendee Website for the applicable Cvent Passkey event. At the conclusion of the registration process, attendees can be forwarded the Cvent Passkey Attendee Website with details auto-populated to streamline the housing reservation process. This business process can be completed using browser-based calls or web service/XML messages. With RegExpress and Basic integrations, the Cvent Passkey attendee website is always utilized to complete reservations for housing.
Note: RegExpress is not intended to be used with RegLink-related Cvent Passkey reporting. However, Basic can deliver that feature/functionality.

Reglink Advanced – Includes all the features provided in RegExpress and Reglink Basic integrations and adds the ability for a third party application to complete all aspects of the attendee creation and reservation process. Unlike RegExpress and Reglink Basic integrations, the use of the Cvent Passkey Attendee Website is not required. A third party application may utilize Reglink calls to manage all phases of the housing reservation process including the ability to fetch housing availability then create, modify and cancel reservations. This is a more complex method than RegExpress or Reglink Basic integrations as it involves following a series of phases to complete the process. This type of integration takes longer to complete and requires more testing to ensure all supported features function as expected.

Licensing – While many features are available with the API, the license model used by Passkey customers may limit available functionality. The two available license models are:

RegLink 1-Way – Information is only sent from the third party application to Passkey. Passkey doesn’t return any data to the system making requests.
RegLink 2-Way – Information is transferred between systems in either direction based on business needs.

If the meeting planner is working with a hotel directly to enable RegLink, the 2-Way license is included. If you are working directly with a meeting planner or CVB/Destination you should have them verify which license they have. If they need assistance they can contact our support team. There is no direct cost to the registration company or technology provider if a Passkey customer is involved. If you are interested in partnering with Passkey and don’t have a customer – either a hotel or meeting planner/CVB/destination – involved, complete our Partner Request Form.

If you have any questions regarding new or existing RegLink licensing, reach out to Cvent Passkey Support.
