For example, WildApricot's Membership Levels API call allows you to retrieve detailed information about your membership levels. As part of an API call, you can include parameters, which are instructions or information used by the API to process your request.WildApricot's API is intended for use by developers with technical expertise. If you want to take advantage of this functionality but lack the technical knowledge, you can engage the services of an approved WildApricot partner or consider using Make to build no-code workflows with WildApricot. If you are a developer and need assistance, we offer support through our Developers forum. By using WildApricot's API, you accept the API License Agreement. Accessing WildApricot's APIsWildApricot's APIs can be accessed from a third-party server or application, or from a WildApricot site page. For information on the differences between the two, see API access options.WildApricot's API adheres to RESTful web service principles. Version 2 API calls take the form of HTML GET, PUT, POST, or DELETE requests formatted in either JSON (JavaScript Object Notation) or XML (Extensible Markup Language). Multiple API requests can be combined in a batch request using the BATCH method.AuthenticationEach WildApricot API call must include authentication information that verifies your account and prevents others from accessing your data. The required authentication information – and how it is passed – differs depending on whether you are accessing the API from a third-party server or application, or from a WildApricot site page. For more information, see API access options.VersioningThe version number of the WildApricot API is included in the API call to allow existing applications to function after new versions are released.In the following example, the v2 value directs the call to version 2 of the WildApricot admin API.GET https://api.wildapricot.org/v2/AccountsA call to the base API – https://api.wildapricot.org – will return a list of available API versions.API responsesResults from WildApricot API calls can be returned in either JSON (JavaScript Object Notation) or XML (Extensible Markup Language) formats. The default format is JSON.To specify the response format, include the following field in the HTTP header:Accept: application/{format}where {format} can be either json or xml.You can compress the response by including the following field in the HTTP header:Accept-Encoding: gzip, deflateFor more information on compressing data in server responses, see HTTP compression.API request limitsCurrently, the limits on the number of API requests per minute are:40 requests per minute to get a list of contacts120 requests per minute to get a contact by identifier400 for other request types.Batch requests are limited to 5 subrequests per batch.Transitioning from API Version 1You should keep the following in mind when you transition your application from Version 1 of WildApricot's API to Version 2.Version 2 of WildApricot API's uses the OAuth authentication standard and issues OAuth authentication tokens. With Version 2, server-side authentication is a two-step process. In the first step, the client application requests an authentication token from the authentication server. In the second step, the authentication server returns an authentication token, which the client application uses in the API call.When accessing version 2 of WildApricot's API, an 3rd-party server or application must first be authorized to access your WildApricot account. During authorization, the application will be assigned a unique API key. Using the API key, your application can request an authentication token. For more information, see API access options.The root node for an XML response to an asynchronous Contacts API call is now ApiResponse. With Version 1, it was AsyncResult.
