# Manage proxy consent for a User

POST https://api.sandbox.mangopay.com/v2.01/{ClientId}/sca/users/{UserId}/consent

Allow a user to give or revoke consent for proxy actions. 

This endpoint allows your platform to manage consent given by the end user for [SCA-triggering actions taken under proxy](/guides/sca/proxy-management).

Your platform needs to retrieve the returned `PendingUserAction.RedirectUrl`, add an encoded `returnUrl` query parameter for them to be returned to after the SCA session, and redirect the user (read more about [SCA redirection](/guides/sca/session)).

On the SCA session link in the response, the user can: 
- Give consent for the first time 
- Give consent to additional actions included by your platform 
- Revoke consent (which your platform must allow at any time)

Reference: https://docs.mangopay.com/api-reference/users/manage-proxy-consent

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token. If your platform is using a [proxy](/guides/sca/proxy-management) to take SCA-triggering action on behalf of users, you also need to integrate [mTLS authentication](/guides/sca/platform) and use the `api-mtls` base URL.

## Servers

- `https://api.sandbox.mangopay.com` (Sandbox, default)
- `https://api.mangopay.com` (Production)
- `https://api-mtls.sandbox.mangopay.com` (mTLS Sandbox)
- `https://api-mtls.mangopay.com` (mTLS Production)

## Request

### Path parameters

- `ClientId` (string, required) — Platform's API account identifier, associated with the API key.
- `UserId` (string, required) — The unique identifier of the user.

## Response

### 200

Success

- `PendingUserAction` (PendingUserAction, optional) — Object containing the `RedirectUrl` needed for SCA redirection if triggered by the API call (otherwise returned `null`).

## Errors

### 400 Bad Request Error

Bad Request

- `Message` (string, optional) — Description of the error.
- `Type` (string, optional) — The category of the error.
- `Id` (string, optional) — Unique identifier of the error instance, useful when contacting Mangopay for support.
- `Date` (double, optional) — Unix timestamp (UTC) of the date and time the error was triggered.
- `errors` (map from string to string, optional, nullable) — Object containing one or more field-level errors.

## Types

### PendingUserAction

Object containing the `RedirectUrl` needed for SCA redirection if triggered by the API call (otherwise returned `null`).

- `RedirectUrl` (string, optional) — The URL to which to redirect the user to perform strong customer authentication (SCA) via a Mangopay-hosted webpage. This value is a variable and should not be hardcoded. The SCA session link expires 10 minutes after it's generated. **Caution:** Before redirecting the user on this URL, you must add the query parameter `ReturnUrl` with the percent-encoded URL to which you want the SCA session to return the user after authentication (whether successful or not). For more details, see [How to redirect a user for an SCA session](/guides/sca/session#how-to-redirect-a-user-for-sca).
