Parameters

Name	In	Type	Description
`State` required	query	string
`Code` required	query	string
`Realm` required	query	string	The realm/company id under its generic name. Kept because the Loopback provider sends `realm`; `realmId` wins when both are present.
`RealmId` required	query	string	The realm/company id under the name Intuit puts on its redirect. QuickBooks Online appends `realmId` to the callback alongside `code` and `state`, and without this property the company id never reaches the connection. Query-string model binding is case-insensitive, so the property name alone binds `realmId`; no attribute is needed and Application.Contracts stays free of an MVC dependency.
`suppressNulls` required	query	boolean	If true, omit properties with null values.

Responses

200 OK

Body: Each item has these fields.

Field	Type	Description

This response has no body.

default The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. See the error-code reference in this document's description for the values `error.code` can take.

Body: RemoteServiceErrorResponse Each item has these fields.

Field	Type	Description
`error` required	RemoteServiceErrorInfo

This response has no documented body fields.

429 The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause.

Body: RemoteServiceErrorResponse Each item has these fields.

Field	Type	Description
`error` required	RemoteServiceErrorInfo

This response has no documented body fields.
