Introduction

The Union Database holds information related to golf clubs and their members.

Continuously the Union Database also holds information about scores of members. Scoring app has access through the API via an API account.

Document Audience

This document is for scoring apps who must post scores into the Union Database.

Definitions

There are a few definitions worth knowing about.

Club
A golf club has an official name, a short name, a number, and possibly an address.

Course
A course is the actual course created by the club. A course has one or more tees with 9 or 18 holes.

Member
A member is a person with one or more memberships. This means that the same person can have two or more memberships of different golf clubs.

Scorecard
A scorecard holds information about the player, the course, the marker, and the actual score.

Identifiers

All objects in the database have identifiers in the form of a GUID (Globally Unique Identifier).

The Scorecard object contains an External ID. This ID is supplied by the scoring app to reference a scorecard in the union database. This makes it simpler to modify a scorecard, because the scoring apps does not need to register the GUID locally.

Data format

The data format used for exchanging data through the API is JSON.

Authentication

Access to the API is done through Basic Authentication. Each vendor will be given an API account with a username and password. Each account is authorized to use a certain set of API resources.

API Set

All requests to the API must include an API Set in the URL. The API Set is equal to the username of the account unless otherwise instructed.

Base URL

The base urls for DGU is

dgubasen.api.union.golfbox.io
test-dgubasen.api.union.golfbox.io

Request headers

All requests to the API must include the following headers:

Content-Type: application/json
Accept: application/json
Authorization: Basic <username:password>
Token: <OAuth token>

The username:password combination must be Base64 encoded.

Token

The token for an API with player information is retrieved through the OAuth 2.0 Authorization Code Flow with PKCE. After the user logs in and grants consent, your application receives an authorization code. This code must then be exchanged for an access token via the token endpoint.

Once retrieved, the access token should be included as a variable in requests to protected API endpoints.

The token grants access based on the scopes requested during authorization (e.g. get_player.information). Be sure to store and transmit the token securely. If needed, refresh the token depending on the lifetime returned in the response.

For more details about OAuth authentication, refer to the OAuth Guide.

Error Handling

If a request fails, the API responds with standard HTTP error codes and messages. If syntax is correct, the API does not return an error — even if the data is invalid. Input is not validated.

Example:

HTTP/1.1 500 Internal Server Error

Clubs

Clubs holds basic information of a given club. Focus point on Clubs is the ID which must be used to lookup courses (See section about Courses)

You can get a single club course by making the following API request. A club course can be referenced by a Club ID and then Course ID

Example Request

GET https://<base_url>/<apiset>//clubs/7AABAF90-9155-4552-889B-553D5CE75FC6/courses/CA1636A2-4D6E-4078-AD38-D7F8BD23D76C

To findt the course to use on a given day:

Ignore Inactive courses
For a given course (TemplateID) find the version with the latest ActivationDate which is not in the future.

Available parameters

When determining which vesion to use if there are many active, the following query parameters can be used when calling the apis above:

GET {{base_url}}/:ApiSet/Clubs/:ClubID/Courses
GET {{base_url}}/:ApiSet/Clubs/:ClubID/Courses/CourseID

Available parameters:
changedsince    - format: yyyymmddTHhmmss, return the courses that changed after a specific date
active          - accept 0 or 1, return courses based on Course.IsActive property, where 0 = inactive and 1 = active
sort            - see tip sort
sortTee         - see tip sortTee
excludeParams   - exclude Course.Tees property from result by including "&excludeParams=tees" parameter

TIP SORT

The courses can be sorted by including the sort parameter.

The parameter must follow this format: PropName:SortDirection,...

PropName can be:
Name, NumberOfHoles, ActivationDate, IsActive, IsHcpQualifying, IsVisible, Version

SortDirection must be 0 or 1, where 0 is ascending and 1 is descending.

Examples:

Sort by highest number of holes: &sort=NumberOfHoles:1
Sort by active and then latest activation date: &sort=IsActive:0,ActivationDate:1

TIP SORTTEE

The Course.Tees properties can be sorted by including the sortTee parameter.

The parameter must follow this format: PropName:SortDirection,...

PropName can be:
Name, Gender, TotalLength, CourseRating, SlopeRating, IsNineHole, LastUpdateDate

SortDirection must be 0 or 1, where 0 is ascending and 1 is descending.

Examples:

Sort by longest tee: &sortTee=TotalLength:1
Sort by gender and then highest course rating: &sortTee=Gender:0,CourseRating:1

Members

Every person in the database has an ID called LifeTimeID. The format of this number is [xxxxxx-xxx], where the first 6 are based on the persons birthdate, and the last 3 are an increment integer grouped by birthdate.

A person can be a member of a golf club. The relationship between a person and club is a membership. A person can also be a member of more than one club, thus having multiple memberships. Being a member in a golf club means that you get a member number, which is unique within the club. This member number has nothing to do with the lifetime ID. If we put together the official club number and the member number, we have a nationally unique reference for a member. This combination is called the ‘union ID’

Member info can be looked up by a lifetime ID or by union ID. Member info consist of both personal info and membership info. When a member is looked up the complete information including the person and all memberships is returned.

Here is a list of the member info.

How do I look up member info?

This is dependent on your access level and agreement.

If you represent a given golf club and have been given access to all members without their consent by the club then you can look up members in that (or those) club(s).
If you are an independent actor you will need player consent to access their information. That is given through the OAuth login and accompanying token - refer to the OAuth Guide.

Re point 1:

You can get info about a specific member in a club you are certified to access by making the following API request. You can refer to the member by • lifetimeID • unionID

Example Request

GET https://<base_url>/<apiset>/Clubs/Golfer?lifetimeID=300191-001?unionID=202-331

}
}
]
}

Re point 2:

You can retrieve information about a specific member who has granted consent by using the token obtained during the authentication process. This is done via the following API.

Example Request

GET https://<base_url>/<apiset>/clubs/Golfer_ByAccessToken

Error in scorecard

If the submitted data contains errors that prevent a valid handicap calculation, no handicap will be calculated. The API simply relays the data you provide—there is no validation, as ScorecardExchange acts as a pass-through to the WHS server. For example, if you submit an incorrect TeeID (e.g. by altering a digit in an otherwise valid course or club GUID), the API will echo back the data, but the scorecard will not appear in the player's record. It is therefore essential to always submit accurate and valid information.

To get couses look up "Ocean View Golf Club DGU" as they have the most courses in the test database

Alternatively "DGU Test Club A II" which also have courses.
