API Requirements
Overview
Thank you for your interest in integrating your POS/Membership system with Perkville! This document outlines the general API requirements and data we typically ingest from membership, scheduling, and point-of-sale systems when Perkville is integrating with your API.
If you’re looking to integrate your system with Perkville, we also offer an API that you can use. You can find the documentation for Perkville's API at https://www.perkville.com/developers/docs/v2/.
By following these guidelines, you’ll enable Perkville to detect new users in your system and track their activities, allowing for custom behaviors to be triggered based on these events.
For any questions, feel free to reach out to us at ops@perkville.com. We’re here to help!
Authentication
Your API should have an authentication scheme that allows us to store a key to authenticate requests on behalf of a specific business. We recommend using OAuth 2's "Authorization Code" grant type. You can refer to this guide for more details.
If OAuth 2 is too complex, consider starting with a simple shared secret. A business can log into their account, find a secret key, and paste it into our application. We’ll use this key for every query.
Additionally, we require a separate key that uniquely identifies Perkville. If you create a custom authentication solution, ensure this key is included to distinguish our system from others that might integrate with your API.
Resources
A "resource" is a record that businesses care about, such as a "user" or "check-in." Your API should allow us to poll for newly added records and perform actions based on the data received.
User
Fields: User ID (Primary Key), Email, First Name, Last Name, Phone Number, Record Last Modified Datetime, (Boolean) Is Child User?, (User ID) Parent ID, and any other personal information.
Query by: Batch primary key, Last modified datetime range.
Location (Facility)
Fields: Location ID (Primary Key), Location Name, Street Address, City, State, Zip Code, Timezone, Record Last Modified Datetime, and any other useful information.
Query by: Complete transfer.
Membership
Fields: Membership ID (Primary Key), User ID (Foreign Key to User), Membership Type, Membership Status, Member Join Date, Cancellation Date, Home Location (Foreign Key to Location), Record Last Modified Datetime, and any other useful information.
Query by: Batch primary key, Last modified datetime range.
Gym Check-in
Fields: Check-in ID (Primary Key), Check-in Datetime, Location ID (Foreign Key to Location), Member ID (Foreign Key to Membership), User ID (Foreign Key to User), Record Last Modified Datetime, and any other useful information.
Query by: Last modified datetime range.
Referral
Fields: Referral ID (Primary Key), Referrer User ID (Foreign Key to User), Referee User ID (Foreign Key to User), Referral Datetime, Record Last Modified Datetime, and any other useful information.
Query by: Last modified datetime range.
Sales
Fields: Sale ID (Primary Key), LineItem ID, LineItem Category ID, LineItem Category Name, LineItem Subcategory ID, LineItem Subcategory Name, LineItem Payment Type, Pre-Tax Price, User ID (Foreign Key to User), Member ID (Foreign Key to Membership), Location ID (Foreign Key to Location), Sale Datetime, Record Last Modified Datetime, and any other useful information.

Fields: Category ID, Category Name, Location ID, and any other useful information.
Query by: Complete transfer.
Sales Subcategory
Fields: Subcategory ID, Subcategory Name, Location ID, and any other useful information.
Query by: Complete transfer.
Class
Fields: Class ID (Primary Key), Class Name, and any other useful information.
Query by: Complete transfer.
Class Attendance
Fields: Class Attendance ID (Primary Key), Class ID, User ID (Foreign Key to User), Membership ID (Foreign Key to Membership), Location ID (Foreign Key to Location), Class Name, Class Datetime, Check-in Datetime, Attended/Checked-in Confirmation (if applicable), and any other useful information.

Query by: Last modified datetime range.
Appointment Category
Fields: Appointment ID, Appointment Name, Location ID (Filterable), and any other useful information.

Querying
Every API endpoint should require authentication and accept the two keys referenced above. Each endpoint should also support paging, ideally allowing up to 10,000 records per page. We support three types of queries:
Complete transfer: Retrieve all records of a specific type.
Batch primary key lookup: We provide a list of primary keys, and you return all matching records.
Last modified datetime range lookup: We provide a datetime range, and you return all records created or modified within that period.
Querying Guidelines for Different Resources
User events (e.g., Check-Ins, Sales): Last modified datetime range query.
Other resources (e.g., User, Membership, Location): Support all three query types where applicable.
Responses
Responses should be UTF-8 encoded.
All datetimes should be in ISO 8601 format with a UTC offset.
Performance
Data related to user interactions (e.g., check-ins or purchases) should be available for consumption immediately upon occurrence.
Integration Platform: Middle
We use our integration platform, Middle, to connect Perkville to various APIs. For more detailed guidelines on building an API for Middle, refer to this guide.
