Overview

An API key must be used to consume this web API. An API key is unique per event, per third-party vendor and must be contracted by the client. Read the EventTech REST API Overview article for information about client expectations when contracting API access for a third-party vendor.

Rate Limiting

To ensure the health and accessibility of our APIs, Cadmium monitors traffic and reserves the right to impose a rate limit or revoke access to any misbehaving application with excessive API usage. A rate limit is a specified number of API requests an application or user can make within a defined time frame.

• A rate limit of one call per minute is enforced for the getAllExhibitorsWithBooth method
• For all other methods, a rate limit of one call per second is enforced
• It’s mandatory to include an expiration or sunset date in your code, usually set as the event’s end date, to ensure that API calls aren’t made unnecessarily beyond that point

Frequently Asked Questions

• The date and times of the data returned by the API are in 24-hour format and are NOT adjusted to GMT or UTC. They are returned exactly as they were entered into the system and represent the native time-zone of the event. 
• To PUSH all exhibitor/booth/staff data:
  • First, push exhibitors via the addUpdateExhibitor method. The API will return ExhibitorID.
  • Second, push booths via the addUpdateBooth method and associate the booth with the correct ExhibitorID by passing the "BoothExhibitorID". The API will return the BoothID.
  • Last, push booth staff via the addUpdateExhibitorStaff method and associate the booth staff with the correct ExhibitorID by passing "StaffExhibitorID".
