# GET /api/hostedpaymentpages/sessions/{sessionId}/level3-data

Returns the Level 3 commercial-card payload stored on a session.

Lets an integrating merchant verify field-by-field exactly what the gateway holds: the stored
payload is returned verbatim (no sanitization or redaction). Because it returns full,
unredacted values, it requires the `HppSessions.Create` permission, and a merchant caller
can only read sessions in its own merchant scope.

**Operation ID:** `hppSessionGetLevel3Data`

## Authorization

Requires: HostedPaymentPage.HppSessions, HostedPaymentPage.HppSessions.Create, merchant scope.

Required permissions:
- `HostedPaymentPage.HppSessions`
- `HostedPaymentPage.HppSessions.Create`

## Parameters

| Name | In | Required | Type | Description |
| --- | --- | --- | --- | --- |
| sessionId | path | yes | string(uuid) | The session whose stored Level 3 data should be returned. |
| suppressNulls | query | no | boolean | If true, omit properties with null values. |

### 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.

**Content type:** `application/json`

Schema: `RemoteServiceErrorResponse`

Properties:
- `error` (RemoteServiceErrorInfo)

### 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.

**Content type:** `application/problem+json`

Schema: `RateLimitProblemDetails`

Properties:
- `type` (string) required: The problem type identifier. Always the same value: the failure is the status code itself,  so there is no sub-type for a caller to branch on.
- `title` (string) required: A short, human-readable summary of the problem type.
- `status` (integer(int32)) required: The HTTP status code, repeated in the body as the problem-details format defines.
- `detail` (string) required: A human-readable explanation of this occurrence of the problem.
- `retryAfterSeconds` (integer(int32)) required: How long to wait before retrying, in whole seconds, carrying the same figure as the  `Retry-After` header. Always at least one: a value of zero would invite an immediate  retry that is certain to be rejected again.

**Content type:** `application/json`

Schema: `RemoteServiceErrorResponse`
