Associates the customer's account with the payment processor to the Google instrument being added.

Account association happens after the integrator has authenticated the user. Association occurs via a server-to-server call that contains the requestId for the associated authentication flow (authenticationRequestId), an associationId and a googlePaymentToken (GPT). The payment processor should associate the associationId and the googlePaymentToken to the customer's account for authentication. The GPT is used to initiate payments. The associationId is used during re-authentication calls to identify the account for authentication.

If Google sends an associationId or a googlePaymentToken that the integrator has already seen during a different association, then it throws an error.

If the endpoint encounters an error while processing the request, the response body from this endpoint should be of type ErrorResponse.

An example request looks like:

{
  "requestHeader": {
    "protocolVersion": {
      "major": 1,
      "minor": 0,
      "revision": 0
    },
    "requestId": "cmVxdWVzdDE",
    "requestTimestamp": "1481899949606"
 },
 "googlePaymentToken": "ZXhhbXBsZSB1bmlxdWUgcGF5bWVudCB0b2tlbiB2YWx1ZQ__",
 "authenticationRequestId": "bnAxdWTydDX==",
 "associationId": "LmddbXBsZSByZWZlcmVuY2UgdG9rZW4gdmFsdWU_",
 "provideUserInformation": true
}

An example response looks like:

Request body

The request body contains data with the following structure:

JSON representation
{ "requestHeader": { object (RequestHeader) }, "provideUserInformation": boolean, "googlePaymentToken": string, "associationId": string, // Union field account_verification can be only one of the following: "authenticationRequestId": string, "otpVerification": { object (OtpVerification) } // End of list of possible types for union field account_verification. }

Fields
requestHeader	object (RequestHeader) REQUIRED: Common header for all requests.
provideUserInformation	boolean REQUIRED: True if we desire the integrator to provide the address associated with this account.
googlePaymentToken	string REQUIRED: The token that Google will use to initiate purchases with the payment processor. This is a string that has a maximum length of 100 characters.
associationId	string REQUIRED: The identifier of this association. This identifier is created by Google and is sent during re-authentication flows to identify which account should be authenticated. This is a string that has a maximum length of 100 characters.
Union field account_verification. account_verification can be only one of the following:
authenticationRequestId	string OPTIONAL: requestId of the authentication request that preceded this call. This identifier was generated by Google during the authentication flow. This is only present if the user went through the Android app authentication, web authentication, or an asynchronous authentication method that uses authenticationResultNotification.
otpVerification	object (OtpVerification) OPTIONAL: Data necessary to verify an OTP generated from sendOtp. This is only present if the user went through the sendOtp path.

Response body

This method supports multiple return types. For additional information about what 4XX or 5XX HTTP status code to return with an ErrorResponse, consult the ErrorResponse object and HTTP status codes documentation.

Possible response messages
HTTP 200 Status	object (AssociateAccountResponse)
HTTP 4XX / 5XX Status	object (ErrorResponse)

AssociateAccountResponse

Response object for the associate account method.

JSON representation

{ "responseHeader": { object (ResponseHeader) }, "paymentIntegratorAssociateAccountId": string, "tokenExpirationTime": string, "accountId": string, "userMessage": string, "userInformation": { object (UserInformation) }, "result": enum (AssociateAccountResultCode), // Union field account_names can be only one of the following: "accountNickname": string, "fullAccountNickname": string // End of list of possible types for union field account_names. }

Fields
responseHeader	object (ResponseHeader) REQUIRED: Common header for all responses.
paymentIntegratorAssociateAccountId	string REQUIRED: This identifier is specific to the integrator and is generated by the integrator. It is used for debugging purposes only in order to identify this call. This is the identifier that the integrator knows this call by.
tokenExpirationTime	string (int64 format) OPTIONAL: Milliseconds since epoch when the token expires. Use 0 to signal the token does not expire.
accountId	string REQUIRED: The account ID the user has with the integrator. This is used for Google risk to understand account re-use and account relationships and Google customer operation agents to help customers diagnose issues. This identifier should be user recognizable (for example the user knows this ID because it appears on their statement or appears on the website after they log into the account). This value must be immutable for the life of the account.
userMessage (deprecated)	string This was never implemented and is being removed in future versions. This field is ignored. DEPRECATED: A description of the result to be displayed to the user if the result is not SUCCESS.
userInformation	object (UserInformation) REQUIRED: User information that the integrator knows and will share with Google about this customer. Used for risk information and address prepopulation.
result	enum (AssociateAccountResultCode) REQUIRED: Result of this association.
Union field account_names. account_names is required if result is ACCEPTED. account_names can be only one of the following:
accountNickname	string OPTIONAL: String by which the user knows this account for display purposes. This is a suffix of the account nickname. For example last four digits of a phone number. Google will indicate in the user interface that this is only a suffix of the nickname. Caution: This value can be PII, but must never be SPII. This value will be displayed in UIs like the purchase flow to allow the user to distinguish between payment methods. Note: that either this value or the fullAccountNickname must be present, never both.
fullAccountNickname	string OPTIONAL: String by which the user knows this account for display purposes. Unlike accountNickname this is the full account nickname. For example 56565-56501 for a phone number or [e-mail] for an email identity. Caution: This value can be PII, but must never be SPII. This value will be displayed in UIs like the purchase flow to allow the user to distinguish between payment methods. Note: that either this value or the accountNickname must be present, never both.
