Selecting a Non-Profit

One of the most common uses of our inventory of fun experiences is to support auction events. We have provided calls to cover everything - adding a non-profit event into our system, selecting certificates to sell at the auction, marking items as sold and generating an invoice for delivery to the non-profit event organizer.

The first step in this process is to identify the non-profit that you are working with. /nonprofit/search allows you to query our extensive database of non-profits by several different fields. We recommend that you utilize the EIN of the non-profit if at all possible. If the non-profit already has a PrivateLabel website and TravelPledge account, then the result set will include a value in the domain field, and this will identify the TravelPledge website of the non-profit

If the non-profit that you would like to work with does not already have a PrivateLabel website in our system, then you will need to POST a call to nonprofit with additional details about the non-profit to create a pending PrivateLabel website in our system so that you can create events. NOTE: You can create events against a pending PrivateLabel, but you will not be able to finalize the event until the information has been reviewed and approved by our website administrators.

If the non-profit that you are working with IS already set up as a PrivateLabel website in our system, then you will need to request access via a POST to nonprofit/access/request. This is to ensure that the administrators for the PrivateLabel in question all know that you are accessing their data and acting on their behalf. You can view the status of your request by making a call to nonprofit/access/status/PENDING. At any point you can see the PrivateLabels that you already have access to by calling nonprofit/access/status/APPROVED. NOTE: You only need to request access to a PrivateLabel website once

Finding / Creating an Event

After you have identified the PrivateLabel that you'll be working with, the next step is to either pull information on their current event or create a new event on their behalf. NOTE: Only a single event can be active for a given PrivateLabel at any time. To see if there are any active events, make a call to event/active/[domain] where [domain] is the domain name of the PrivateLabel. If there are no active events, you can create one by making a POST to event.

Selecting Certificates

There are two options available for selecting certificates for an event. The easiest, and suggested, method is to let Geronimo Solutions pick it for you when you are creating an event by setting the value of autopopulate on the event object to true. Alternatively, you can search for specific certificates using certificates?type=, where type is the type of certificate that you would like to pull. e.g.: Golf, Vacation, Lesson, etc. NOTE: You can also specify other search criteria beyond just type to narrow down your results.

If you are manually adding certificates, once you have identified the certificate that you would like to use for your event, make a note of its certificate id and PUT the event into the selectedcertificates property of the event in a call to event.

Hold Your Event!

Mark Selected Certificates as Sold/Not Sold

Each certificate that you select for your event must be marked as either sold or not sold after the event has completed. Your auction software knows which items were sold and this information simply needs to be passed back to Geronimo Solutions so we can generate an invoice. For the certificates that were sold during the event, we will need to collect some basic information about the winner, and how much the certificates sold for. This will allow us to ensure that the certificates are delivered to the winning bidders in a timely manner and the funds are collected from the non-profit. You can provide this information in a similar manner that you manually selected them (if you chose to go that route), by adding them to the soldcertificates property of the event in a PUT call to event.

Once you have updated the final status of all of your selected certificates, you can view the invoice for your event by calling event/[eventid]/invoice, where [eventid] is the id of your event.

As an alternative to both of the above calls, you can mark the certificate status, and view the invoice, by logging into the admin area of the PrivateLabel and closing out the event there.
