Free-form, so campaign and channel origins can be introduced without an API change. In-store applications use one of `in_store_associate`, `in_store_kiosk`, or `in_store_signage`; a server-verified in-store application overrides whatever value you supply. example: in_store_kiosk PartnerCustomerId: type: string minLength: 1 maxLength: 128 pattern: ^[\x20-\x7E]+$ description: | The unique identifier for the customer in the partner's system. Compared byte-for-byte, so `PARTNER_USER_456` and `partner_user_456` are two different customers. Send the same casing everywhere or a later lookup silently returns no match. Restricted to printable ASCII (`\x20`–`\x7E`) rather than arbitrary UTF-8: the value is propagated between internal services as an HTTP/2 header, which cannot carry non-ASCII bytes. The bound is published rather than discovered. example: PARTNER_USER_456 CustomerAccountHistory: type: object description: A Customer's account history with the partner properties: email: type: string format: email description: Customer's email address example: customer@example.com phone: type: string description: Customer's phone number in E.164 format example: '+14155552671' first_name: type: string description: The customer's first name example: John last_name: type: string description: The customer's last name example: Doe preferred_language: type: string description: Customer's preferred language code as defined by ISO 639-1 example: en address: $ref: '#/components/schemas/Address' account_tenure: type: integer description: The customer's account tenure with the partner, in months example: 13 ltv_amount: type: integer description: >- The Life Time Value for the customer's account, in the min currency unit (cents for USD) example: 34000 ltv_currency: type: string description: The 3 char currency code of the amount in iso-4217 example: USD loyalty_tier: type: string description: The customer's current loyalty tier example: GOLD account_created_at: type: string description: >- The RFC-3339 timestamp when the customer's account was created with the partner example: '2025-02-13T19:08:07.000Z' transaction_count: type: integer description: >- The number of lifetime transactions the customer has made with the partner example: 100 Address: type: object description: Mailing address information properties: street_line1: type: string description: Primary street address example: 123 Main St street_line2: type: string description: Secondary street address (apartment, suite, etc.) example: Apt 4B city: type: string description: City name example: San Francisco state: type: string description: State or province example: CA postal_code: type: string examples: - '94105' - 94105-1234 country: type: string description: ISO-3166-1 alpha-3 Country Code example: USA securitySchemes: basicAuth: type: http scheme: basic description: >- Basic HTTP authentication.
