-## 3D Secure Authentication during payment profile creation.
+## 3D Secure (3DS) Authentication post-authentication flow
 
-When a payment requires 3D Secure Authentication to adhear to Strong Customer Authentication (SCA) during payment profile creation, the request enters a [post-authentication flow](https://maxio.zendesk.com/hc/en-us/articles/24176278996493-Testing-Implementing-3D-Secure#psd2-flows-pre-authentication-and-post-authentication). In this case, a 422 Unprocessable Entity status is returned with the following response:
+When a payment requires 3DS Authentication to adhere to Strong Customer Authentication (SCA), the request enters a post-authentication flow where a 422 Unprocessable Entity status is returned with an action_link that will direct the customer through 3DS Authentication.
 
-```json
-{
-    "jsonapi": {
-        "version": "1.0"
-    },
-    "errors": [
-        {
-            "title": "This card requires 3DSecure verification.",
-            "detail": "This card requires 3D secure authentication. Redirect the customer to the URL from the action_link attribute to authenticate. Attach callback_url param to this URL if you want to be notified about the result of 3D Secure authentication. Attach redirect_url param to this URL if you want to redirect a customer back to your page after 3D Secure authentication. Example: https://checkout-test.chargifypay.test/3d-secure/checkout/pay_uerzhsxd5uhkbodx5jhvkg6yeu?one_time_token_id=93&callback_url=http://localhost:4000&redirect_url=https://yourpage.com will do a POST request to https://localhost:4000 after credit card is authenticated and will redirect a customer to https://yourpage.com after 3DS authentication.",

-            }
-        }
-    ]
-}
-```
-
-To let the customer go through 3D Secure Authentication, they need to be redirected to the URL specified in `action_link`.
-
-Optionally, you can specify the `callback_url` parameter in the `action_link` URL to receive notification about the result of 3D Secure Authentication.
-
-The `callback_url` will return the following information:
-
-- whether the authentication was successful (`success`)
-- the payment profile ID (`payment_profile_id`)
-
-You can also specify a `redirect_url` parameter in the `action_link` URL to redirect the customer back to your site.
-
-You cannot use action_link in an iframe inside a custom application. You must redirect the customer directly to the `action_link` and use the `redirect_url` or `callback_url` to be notified of the result.
-
-The final URL that you send a customer to complete 3D Secure may resemble the following, where the first half is the `action_link` and the second half contains a `redirect_url` and `callback_url`:
-
-`https://checkout-test.chargifypay.test/3d-secure/checkout/pay_uerzhsxd5uhkbodx5jhvkg6yeu?one_time_token_id=93&callback_url=http://localhost:4000&redirect_url=https://yourpage.com`
-
-### Example Redirect Flow
-
-Here's an example flow to redirect customers to different pages depending on whether SCA was performed successfully:
-
-1. Create a payment profile via the API; it requires 3DS.
-2. You receive an `action_link` in the response.
-3. Use this `action_link` to, for example, connect with your internal resources or generate a `session_id`.
-4. Include one of those attributes inside the `callback_url` and `redirect_url` to be aware which “session” this applies to.
-5. Redirect the customer to the `action_link` with `callback_url` and `redirect_url` applied
-6. After the customer completes 3DS authentication, we notify you of the result via the applied `callback_url`.
-7. After that, we redirect the customer to the `redirect_url`; at this point the result of authentication is known.
-8. Optionally, you can use the applied "msg" param in the `redirect_url` to determine if the redirect was successful.
+See the [3D Secure Post-Authentication Flow](https://docs.maxio.com/hc/en-us/articles/44277749524365-3D-Secure-Post-Authentication-Flow) article in the product documentation to learn how to manage the redirect flow.

-## Migration 3D Secure - Stripe
-
-When a payment requires 3D Secure Authentication to adhear to Strong Customer Authentication (SCA) when the subscription is migrated to a new product, the request enters a [post-authentication flow](https://maxio.zendesk.com/hc/en-us/articles/24176278996493-Testing-Implementing-3D-Secure#psd2-flows-pre-authentication-and-post-authentication). The server returns `422 Unprocessable Entity` in this case with the following response:
-
-```json
-{
-  "errors": [
-    "Your card was declined. This transaction requires 3D secure authentication."
-  ],
-  "gateway_payment_id": "pi_1F0aGoJ2UDb3Q4av7zU3sHPh",
-  "description": "This card requires 3D secure authentication. Redirect the customer to the URL from the action_link attribute to authenticate. Attach callback_url param to this URL if you want to be notified about the result of 3D Secure authentication. Attach redirect_url param to this URL if you want to redirect a customer back to your page after 3D Secure authentication. Example: https://mysite.chargify.com/3d-secure/pi_1FCm4RKDeye4C0XfbqquXRYm?one_time_token_id=128&callback_url=https://localhost:4000&redirect_url=https://yourpage.com will do a POST request to https://localhost:4000 after payment is authenticated and will redirect a customer to https://yourpage.com after 3DS authentication.",
-  "action_link": "http://acme.chargify.com/3d-secure/pi_1F0aGoJ2UDb3Q4av7zU3sHPh?one_time_token_id=242"
-}
-```
-
-To let the customer go through 3D Secure Authentication, they need to be redirected to the URL specified in `action_link`.
-Optionally, you can specify `callback_url` parameter in the `action_link` URL if you’d like to be notified about the result of 3D Secure Authentication. The `callback_url` will return the following information:
-
-- whether the authentication was successful (`success`)
-- the gateway ID for the payment (`gateway_payment_id`)
-- the subscription ID (`subscription_id`)
+Important note: One of the most common ways that a migration can fail is when the attempt is made to migrate a subscription to its current product.
 
-Lastly, you can also specify a `redirect_url` within the `action_link` URL if you’d like to redirect a customer back to your site.
+## 3D Secure (3DS) Authentication post-authentication flow
 
-It is not possible to use `action_link` in an iframe inside a custom application. You have to redirect the customer directly to the `action_link`, then, to be notified about the result, use `redirect_url` or `callback_url`.
+When a payment requires 3DS Authentication to adhere to Strong Customer Authentication (SCA), the request enters a post-authentication flow where a 422 Unprocessable Entity status is returned with an action_link that will direct the customer through 3DS Authentication.
 
-The final URL that you send a customer to to complete 3D Secure may resemble the following, where the first half is the `action_link` and the second half contains a `redirect_url` and `callback_url`: `https://mysite.chargify.com/3d-secure/pi_1FCm4RKDeye4C0XfbqquXRYm?one_time_token_id=128&callback_url=https://localhost:4000&redirect_url=https://yourpage.com`
-
-### Example Redirect Flow
-
-You may wish to redirect customers to different pages depending on whether SCA was performed successfully. Here's an example flow to use as a reference:
-
-1. Create a migration via API; it requires 3DS
-2. You receive a `gateway_payment_id` in the `action_link` along other params in the response.
-3. Use this `gateway_payment_id` to, for example, connect with your internal resources or generate a session_id
-4. Include 1 of those attributes inside the `callback_url` and `redirect_url` to be aware which “session” this applies to
-5. Redirect the customer to the `action_link` with `callback_url` and `redirect_url` applied
-6. After the customer finishes 3DS authentication, we let you know the result by making a request to applied `callback_url`.
-7. After that, we redirect the customer to the `redirect_url`; at this point the result of authentication is known
-8. Optionally, you can use the applied "msg" param in the `redirect_url` to determine whether it was successful or not.

+Sets certain subscription fields that are usually managed automatically. Some of the fields can be set via the normal Subscriptions Update API, but others can only be set using this endpoint.
 
 This endpoint is provided for cases where you need to “align” Advanced Billing data with data that happened in your system, perhaps before you started using Advanced Billing. For example, you may choose to import your historical subscription data, and would like the activation and cancellation dates in Advanced Billing to match your existing historical dates. Advanced Billing does not backfill historical events (i.e. from the Events API), but some static data can be changed via this API.

-     * }
-     * }
-     * ]
-     * }
-     * ```
-     * To let the customer go through 3D Secure Authentication, they need to be redirected to the URL
-     * specified in `action_link`.
-     *
-     * Optionally, you can specify the `callback_url` parameter in the `action_link` URL to receive
-     * notification about the result of 3D Secure Authentication.
-     *
-     * The `callback_url` will return the following information:
-     *
-     * - whether the authentication was successful (`success`)
-     * - the payment profile ID (`payment_profile_id`)
-     *
-     * You can also specify a `redirect_url` parameter in the `action_link` URL to redirect the customer
-     * back to your site.
-     *
-     * You cannot use action_link in an iframe inside a custom application. You must redirect the customer
-     * directly to the `action_link` and use the `redirect_url` or `callback_url` to be notified of the
-     * result.
-     *
-     * The final URL that you send a customer to complete 3D Secure may resemble the following, where the
-     * first half is the `action_link` and the second half contains a `redirect_url` and `callback_url`:
-     *
-     * `https://checkout-test.chargifypay.test/3d-secure/checkout/pay_uerzhsxd5uhkbodx5jhvkg6yeu?
-     * one_time_token_id=93&callback_url=http://localhost:4000&redirect_url=https://yourpage.com`
-     *
-     * ### Example Redirect Flow
-     *
-     * Here's an example flow to redirect customers to different pages depending on whether SCA was
-     * performed successfully:
-     *
-     * 1. Create a payment profile via the API; it requires 3DS.
-     * 2. You receive an `action_link` in the response.
-     * 3. Use this `action_link` to, for example, connect with your internal resources or generate a
-     * `session_id`.
-     * 4. Include one of those attributes inside the `callback_url` and `redirect_url` to be aware which
-     * “session” this applies to.
-     * 5. Redirect the customer to the `action_link` with `callback_url` and `redirect_url` applied
-     * 6. After the customer completes 3DS authentication, we notify you of the result via the applied
-     * `callback_url`.
-     * 7. After that, we redirect the customer to the `redirect_url`; at this point the result of
-     * authentication is known.
-     * 8. Optionally, you can use the applied "msg" param in the `redirect_url` to determine if the
-     * redirect was successful.
+     * See the [3D Secure Post-Authentication Flow](https://docs.maxio.com/hc/en-us/articles/44277749524365-
+     * 3D-Secure-Post-Authentication-Flow) article in the product documentation to learn how to manage the

-     * ```json
-     * {
-     * "errors": [
-     * "Your card was declined. This transaction requires 3D secure authentication."
-     * ],
-     * "gateway_payment_id": "pi_1F0aGoJ2UDb3Q4av7zU3sHPh",
-     * "description": "This card requires 3D secure authentication. Redirect the customer to the URL from
-     * the action_link attribute to authenticate. Attach callback_url param to this URL if you want to be
-     * notified about the result of 3D Secure authentication. Attach redirect_url param to this URL if you

-     * one_time_token_id=242"
-     * }
-     * ```
-     *
-     * To let the customer go through 3D Secure Authentication, they need to be redirected to the URL
-     * specified in `action_link`.
-     * Optionally, you can specify `callback_url` parameter in the `action_link` URL if you’d like to be
-     * notified about the result of 3D Secure Authentication. The `callback_url` will return the following
-     * information:
-     *
-     * - whether the authentication was successful (`success`)
-     * - the gateway ID for the payment (`gateway_payment_id`)
-     * - the subscription ID (`subscription_id`)
-     *
-     * Lastly, you can also specify a `redirect_url` within the `action_link` URL if you’d like to redirect
-     * a customer back to your site.
-     *
-     * It is not possible to use `action_link` in an iframe inside a custom application. You have to
-     * redirect the customer directly to the `action_link`, then, to be notified about the result, use
-     * `redirect_url` or `callback_url`.
-     *
-     * The final URL that you send a customer to to complete 3D Secure may resemble the following, where
-     * the first half is the `action_link` and the second half contains a `redirect_url` and `callback_url`:
-     * `https://mysite.chargify.com/3d-secure/pi_1FCm4RKDeye4C0XfbqquXRYm?
-     * one_time_token_id=128&callback_url=https://localhost:4000&redirect_url=https://yourpage.com`
-     *
-     * ### Example Redirect Flow
-     *
-     * You may wish to redirect customers to different pages depending on whether SCA was performed
-     * successfully. Here's an example flow to use as a reference:
-     *
-     * 1. Create a migration via API; it requires 3DS
-     * 2. You receive a `gateway_payment_id` in the `action_link` along other params in the response.
-     * 3. Use this `gateway_payment_id` to, for example, connect with your internal resources or generate a
-     * session_id
-     * 4. Include 1 of those attributes inside the `callback_url` and `redirect_url` to be aware which
-     * “session” this applies to
-     * 5. Redirect the customer to the `action_link` with `callback_url` and `redirect_url` applied
-     * 6. After the customer finishes 3DS authentication, we let you know the result by making a request to
-     * applied `callback_url`.
-     * 7. After that, we redirect the customer to the `redirect_url`; at this point the result of
-     * authentication is known
-     * 8. Optionally, you can use the applied "msg" param in the `redirect_url` to determine whether it was
-     * successful or not.
+     * Important note: One of the most common ways that a migration can fail is when the attempt is made to
+     * migrate a subscription to its current product.
+     *
+     * ## 3D Secure (3DS) Authentication post-authentication flow
+     *
+     * When a payment requires 3DS Authentication to adhere to Strong Customer Authentication (SCA), the
+     * request enters a post-authentication flow where a 422 Unprocessable Entity status is returned with
+     * an action_link that will direct the customer through 3DS Authentication.

 A subscription may only have one advance invoice per billing period. Attempting to issue an advance invoice when one already exists will return an error.
 That said, regeneration of the invoice may be forced with the params `force: true`, which will void an advance invoice if one exists and generate a new one. If no advance invoice exists, a new one will be generated.
