# PUT /api/merchants/{id}/three-d-secure-bindings/{providerType}

3-D Secure: creates or replaces the merchant's binding for one provider.

Example body:
```
{
  "isEnabled": true,
  "policyMode": "Attempt",
  "apiKey": "…",
  "jwtSecret": "…",
  "endpointEnvironment": "Sandbox",
  "requestorUrl": "https://checkout.example.com",
  "challengeEnabled": true,
  "protocolVersion": "2.2.0"
}
```
Omitting `jwtSecret` keeps the secret already stored, which is what a caller that read the
binding first will naturally send, because reads never return it. Optionally send
`If-Match: "<concurrencyStamp>"` for optimistic concurrency (409 on a stale stamp).

**Operation ID:** `merchantThreeDSBindingUpsertThreeDSBinding`

## Authorization

Requires: Merchants.Merchants.Update, merchant scope.

Requires API key scope: `admin`

Required permissions:
- `Merchants.Merchants.Update`

## Parameters

| Name | In | Required | Type | Description |
| --- | --- | --- | --- | --- |
| id | path | yes | string(uuid) | The merchant id. |
| providerType | path | yes | [ThreeDSProviderType](https://devportal.demo.winkpg.io/docs/api/models/ThreeDSProviderType.md) | The provider to bind (authoritative; any provider on the body is ignored). |
| suppressNulls | query | no | boolean | If true, omit properties with null values. |

**`providerType` values**

| Value | Description |
| --- | --- |
| `Fake` | Deterministic in-memory provider that performs no network calls. The local-dev, CI, and default-selection provider, and the safe landing spot for an absent configuration value. |
| `Paay` | Paay (API brand "3DS Integrator"), reached over its Direct API. Supports authentication, the 3DS Method step, the cardholder challenge, and 3RI; it documents no decoupled or Secure Payment Confirmation capability, so the registry refuses those. |

## Request Body

The binding content. Omitted fields are cleared (PUT replace semantics).

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

Schema: [`MerchantThreeDSBinding`](https://devportal.demo.winkpg.io/docs/api/models/MerchantThreeDSBinding.md)

Properties:
- `providerType` ([ThreeDSProviderType](https://devportal.demo.winkpg.io/docs/api/models/ThreeDSProviderType.md)): Which 3-D Secure provider this entry binds the merchant to. A null provider type is treated  as no binding at all rather than as `Fake`, so an incompletely  boarded row cannot silently become a live selection. (nullable)
  Values:
  - `Fake`: Deterministic in-memory provider that performs no network calls. The local-dev, CI, and default-selection provider, and the safe landing spot for an absent configuration value.
  - `Paay`: Paay (API brand "3DS Integrator"), reached over its Direct API. Supports authentication, the 3DS Method step, the cardholder challenge, and 3RI; it documents no decoupled or Secure Payment Confirmation capability, so the registry refuses those.
- `isEnabled` (boolean): Master enable flag for this provider on this merchant. When `false` or null, the binding  is not used even though the row exists. (nullable)
- `policyMode` ([ThreeDSPolicyMode](https://devportal.demo.winkpg.io/docs/api/models/ThreeDSPolicyMode.md)): How hard the merchant wants authentication applied. Null means the platform default, which  callers read as `Off`. (nullable)
  Values:
  - `Off`: Do not attempt 3-D Secure at all. The safe landing spot for an absent stored value.
  - `Attempt`: Attempt authentication, but continue with the payment when it cannot be completed. Liability shift is taken where the issuer grants it and forgone where it does not.
  - `Require`: Attempt authentication and refuse the payment when it cannot be completed. The merchant has chosen never to process an unauthenticated transaction on the surfaces this applies to.
- `apiKey` (string): The vendor API key. Not a secret in the sense the JWT secret is (it is sent as a request  header and appears as a JWT audience), so it round-trips on reads; it is still never logged. Required: When IsEnabled is true. (nullable, max length 256)
- `jwtSecret` (string): The shared secret the request JWT is signed with.                   <b>Stored encrypted.</b> It is stripped, not decrypted, on every read that leaves the server:  the admin UI and the API both see null here and re-send the secret only when the operator  changes it. Only the server-side call to the provider ever uses the plaintext. (nullable, max length 512)
- `jwtSecretConfigured` (boolean): Whether a JWT secret is stored for this binding, for the editor that is never allowed to see the  secret itself. (nullable)
- `endpointEnvironment` ([ThreeDSEndpointEnvironment](https://devportal.demo.winkpg.io/docs/api/models/ThreeDSEndpointEnvironment.md)): Which of the vendor's environments this binding points at. Null reads as  `Sandbox`. (nullable)
  Values:
  - `Sandbox`: The vendor's test environment. The safe landing spot for an absent stored value.
  - `Live`: The vendor's production environment.
- `requestorUrl` (string): The merchant-facing origin the vendor validates authentication requests against: the HPP or  checkout origin the cardholder's browser is on. HTTPS only. Conditional: When RequestorUrl is not empty. Required: When IsEnabled is true. (nullable, max length 512)
- `challengeEnabled` (boolean): Whether the merchant permits the vendor to raise an interactive challenge. Null reads as not  enabled. (nullable)
- `protocolVersion` (string): The 3-D Secure protocol version to request, from  `SupportedProtocolVersions`. Null means the provider's own  default. Conditional: When ProtocolVersion is not empty. (nullable, max length 16)
- `providerRegistrationId` (string(uuid)): Optional pointer at a vendor-side registration record for this merchant, for vendors that  board a merchant out of band and hand back an identifier. Nullable because most bindings  carry credentials and nothing else, and because a deleted registration should leave an  inspectable dangling reference rather than a hard failure. (nullable)

_Example: Request failed validation_

One or more fields were rejected before any rule ran. error.code is null on the envelope and the causes are in validationErrors, one entry per failure. An entry carries code when the validator declared a publishable one, and memberPaths when the full path says more than members does (an element inside a collection, for example). Both keys are omitted when they would add nothing.

```json
{
  "error": {
    "code": "null",
    "message": "Your request is not valid!",
    "details": "The following errors were detected during validation.",
    "data": {

        "members": [
          "amount"
        ]
      },

Properties:

_Example: Resource not found_

The id in the path names no record the caller can see. Most resources answer with a null error.code and a message naming the resource type and the id; a resource that publishes a not-found code in the catalog above carries it in error.code instead, so check for one before matching on the message.

```json
{
  "error": {
    "code": "null",
    "message": "There is no entity Transaction with id = 7d1f3a52-0c4e-4b8a-9e21-5a6b7c8d9e00!",

### 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. The [error reference](https://devportal.demo.winkpg.io/docs/errors.md) lists the values `error.code` can take.

_Example: Business rule refused the request_

The request was understood and rejected by a platform rule. This is the shape that carries a code from the catalog above, so branch on error.code rather than on the message text. The HTTP status is the one listed against the code.

```json
{
  "error": {
    "code": "Transactions:OperationNotAllowed",
    "message": "The operation 'Void' is not allowed on a Sale transaction with result 'Approved' and settlement state 'Settled'.",

    "data": {
      "correlationId": "0123456789abcdef0123456789abcdef"
    },
    "validationErrors": "null"
  }
}
```

### 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`](https://devportal.demo.winkpg.io/docs/api/models/RateLimitProblemDetails.md)

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. (nullable)
- `title` (string) required: A short, human-readable summary of the problem type. (nullable)
- `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. (nullable)
- `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.
