Eventscribe Registration API

Every call needs an account token, which is unique to each client. Every call except getMeetingsXML also needs an activity token, which is unique to each event. Use getMeetingsXML to look up the activity token for each of your events.

• Send parameters as a query string on a GET request, or as form fields on a POST request. Both work for every call, including the calls that write data.
• Parameter names are case-sensitive. AccountToken works; accounttoken returns an error.
• URL-encode every value, including spaces, slashes, colons, and @.
• Flags such as ShowUDFs must be 1 to turn on.

• All times are U.S. Eastern Time.
• Send StartTime and EndTime as MM/DD/YYYY HH:MM:SS in 24-hour time, URL-encoded (for example, 10%2F08%2F2026%2015%3A00%3A00). A date alone covers the whole day. You can send either parameter on its own.
• Responses use M/D/YYYY h:mm AM (for example, 10/8/2026 3:52 PM).

• Responses are XML encoded as UTF-8.
• Empty values come back as empty elements (for example, <Room></Room>), not missing elements.
• An unlimited capacity is returned as 268435455.
• getRegistrationInformationXML, getPurchasesXML, and getPaymentsXML return at most about 10,000 records per call. For large events, request smaller time windows.
• Calls that write data return <Success></Success> when they succeed.

Errors return a single <Error> element with a message. Check every response for an <Error> element rather than relying on the HTTP status code.

<Error>Registrant 1 not found</Error>

Common causes are a missing required parameter, an ID that doesn’t belong to the event, or a workshop that doesn’t belong to the session you sent.

• Send every value your event requires. Questions that are required on the registration form aren’t enforced through the API.
• Search before you create. submitRegistrationXML creates a new registrant on every call. Use searchRegistrationInformationXML to check for an existing registrant first.
• Send choice IDs from the question’s own list. For dropdown and radio-button questions, use only the choice IDs that belong to that question.
• Check registration status before you update. Updates apply to cancelled registrants too.
• Send dates as MM/DD/YYYY. Date questions store the value exactly as sent.
• Re-read after an error. If a write method returns an error, some values in the request may already be saved. Read or search for the registrant before you retry.

Custom question (UDF) value formats

To write a custom question, send a parameter named UDF followed by the UDFID (for example, UDF899841=522587). Values you leave out are unchanged. Values you send empty are cleared. A UDFID that doesn’t belong to the event returns an error.

Returns the events (meetings) on your account, including each event’s activity token. This is the only call that doesn’t need an activity token.

HTTP Method: GET or POST

Categories is a comma-separated list of the categories the event belongs to. StartDate and EndDate are empty when the event has no dates set.

Request Example:

https://websvcs.edgereg.net/er/API/EROnline/getMeetingsXML.jsp?AccountToken=YOUR_ACCOUNT_TOKEN&ShowLastActivity=1

Response Example:

<?xml version="1.0" encoding="UTF-8" ?>

    <Categories></Categories>
    <LastActivityDate>10/8/2026</LastActivityDate>
  </Meeting>
</Meetings>

Returns the event’s fees. Use FeeItemID from a Registration fee with submitRegistrationXML.

HTTP Method: GET or POST

FeeType is Registration for registration fees or Options for add-on items. CapacityLimit is 268435455 when the fee has no limit.

Returns full registrant records: contact information, and optionally custom question answers, workshops, and registration fee.

HTTP Method: GET or POST

• With no RegistrantID and no times, the call returns every active registrant in the event, up to about 10,000. Use a time window for large events.
• Active means registered, attended, bad check, or bill later. Cancelled, deleted, and waitlisted registrants aren’t included.
• The time filter uses the original registration time. To find registrants who changed after registering, use the change-tracking calls below.
• Cancelled registrants are left out of time-window and all-registrant results, but you can still retrieve one by RegistrantID.
• BalanceDue is negative when the registrant owes money and 0.00 when paid in full.
• ConsentQuestions is always included and lists the registrant’s answer to each consent question.
• A RegistrantID that doesn’t exist returns <Error>Registrant 1 not found</Error>.

Searches registrants by name. Matching is case-insensitive and matches the start of the name only: LastName=don finds “Donovan”, but LastName=novan doesn’t.

HTTP Method: GET or POST

• FirstName and LastName together must contain at least two characters. Shorter searches, or searches with no matches, return an empty <Registrations> element rather than an error.
• Results also include BadgeDisplay, IsMember, FullName, and MembershipInfoUpdated. Social media elements are LinkedInProfileUrl, FacebookProfileUrl, and XUsername.
• The registration fee isn’t available from search. Use getRegistrationInformationXML with the returned RegistrantID.

Returns registrants who registered, were updated, or had a purchase or payment in the time window. This is the best single call for keeping another system in sync.

HTTP Method: GET or POST

With no times, the call returns every registrant who has ever changed.

Request Example:

https://websvcs.edgereg.net/er/API/EROnline/getAllChangedRegistrationsXML.jsp?AccountToken=YOUR_ACCOUNT_TOKEN&ActivityToken=YOUR_ACTIVITY_TOKEN&StartTime=10%2F08%2F2026%2015%3A00%3A00&EndTime=10%2F08%2F2026%2023%3A59%3A59

<Registrations>
  <RegistrantID>9509894</RegistrantID>
  <RegistrantID>9509902</RegistrantID>
</Registrations>

Returns registrants who were updated after they registered. New registrations aren’t included; use getAllChangedRegistrationsXML to catch both.

HTTP Method: GET or POST

Response Example:

<?xml version="1.0" encoding="UTF-8" ?>
<Registrations>
  <RegistrantID>9509835</RegistrantID>
  <RegistrantID>9509836</RegistrantID>
</Registrations>

Returns registrants who are no longer attending the event. This call has no time filter; it always returns every cancelled registrant who matches the filters.

HTTP Method: GET or POST

“Cancelled” includes registrants who were cancelled or deleted.

Response Example:

<?xml version="1.0" encoding="UTF-8" ?>
<Registrations>
  <RegistrantID>9509835</RegistrantID>
</Registrations>

Returns registrants who had a registration fee cancelled. This doesn’t necessarily mean the registrant is no longer attending. For example, a registrant who exchanges one registration fee for another has a cancellation and a new purchase, and appears here but not in getCancelledRegistrantsXML.

HTTP Method: GET or POST

Response Example:

<?xml version="1.0" encoding="UTF-8" ?>
<Registrations>
  <RegistrantID>9509835</RegistrantID>
  <RegistrantID>9509836</RegistrantID>
</Registrations>

Returns the fees each registrant currently holds, grouped by purchase transaction.

HTTP Method: GET or POST

Send at least one of RegistrantID, StartTime, or EndTime.

Returns payments and discounts applied to billing accounts.

HTTP Method: GET or POST

TXType describes the transaction. Credits (refunds) have positive Amount values, the same as payments; use TXType to tell them apart. This call can return:

Purchases, cancellations, future credits, surcharges, and exchange-rate adjustments aren’t returned. PaymentDetail depends on the type:

• Credit card (payments and credits): CreditCardType (may be empty), LastFourCreditCard, and OrderNumber
• Check: CheckNumber
• Discount: DiscountCode. Amount is the amount taken off.

Creates a new registrant with one registration fee and returns the new RegistrantID and BillingID. No payment is collected. The registrant is set to pay later, and their balance is the fee price minus any discount. A $0 fee is recorded as complimentary.

⚠️ Sends a confirmation email. If you include Email, Eventscribe Registration sends the event’s registration confirmation email to that address. Leave Email out if your system sends its own confirmation.

HTTP Method: GET or POST

• Workshops and option fees can’t be added in this call. Use updateWorkshopXML to add workshops afterward. Option fees can’t be added through the API.

Request Example:

https://websvcs.edgereg.net/er/API/EROnline/submitRegistrationXML.jsp?AccountToken=YOUR_ACCOUNT_TOKEN&ActivityToken=YOUR_ACTIVITY_TOKEN&FeeItemID=731441&FirstName=Priya&LastName=Natarajan&Email=priya.natarajan.test%40example.com&UDF899841=522599&UDF899842=522580&DiscountCode=10OFF

Updates a registrant’s contact information and custom question answers, and records attendance. Send only the fields you want to change.

HTTP Method: GET or POST

• Fields you leave out are unchanged. Fields you send with an empty value are cleared.
• State and country: set State when you create the registrant with submitRegistrationXML; changing an existing state isn’t supported through this method. Send Country in its own request, as a two-letter code (US) or full name (United States).
• A UDFID that isn’t in the event returns <Error>UDFID 1 does not belong to provided Activity.</Error>.
• A value longer than a question’s character limit returns an error such as UDFID 901939 has a limit of 3 but the value provided is 5 characters.

Request Example:

https://websvcs.edgereg.net/er/API/EROnline/updateRegistrantInformationXML.jsp?AccountToken=YOUR_ACCOUNT_TOKEN&ActivityToken=YOUR_ACTIVITY_TOKEN&RegistrantID=9509894&Attended=1&Title=Director%20of%20Interventional%20Cardiology&UDF901930=Yes
