The type of this field is nilable +ExchangeRequestLocale+ (string enum).

Request support for additional languages [here](https://docs.google.com/forms/d/e/1FAIpQLScZSpAu_m2AmLXRT3F3kap-s_mcV6UTBitYn6CdyWP0-o7YjQ/viewform?usp=sf_link")!

Currently supported languages are English (`"en"`), Spanish (`"es"`), and Brazilian Portuguese (`"pt-br"`); if no value is provided, the copy defaults to English.

Parameter is a [IETF BCP 47 language tag](https://www.w3.org/International/articles/language-tags/), e.g. `"en"`.

If the Member needs to complete an MFA step, and the Member has a phone number, this endpoint will pre-emptively send a one-time passcode (OTP) to the Member's phone number. The locale argument will be used to determine which language to use when sending the passcode.

== Parameters:

The `session_duration_minutes` and `session_custom_claims` parameters will be ignored.
The `intermediate_session_token` can also be used with the [Exchange Intermediate Session endpoint](https://stytch.com/docs/b2b/api/exchange-intermediate-session) or the [Create Organization via Discovery endpoint](https://stytch.com/docs/b2b/api/create-organization-via-discovery) to join a different Organization or create a new one.
The `intermediate_session_token` can be passed into the [OTP SMS Authenticate endpoint](https://stytch.com/docs/b2b/api/authenticate-otp-sms) to complete the MFA step and acquire a full member session.
If the Member is required to complete MFA to log in to the Organization, the returned value of `member_authenticated` will be `false`, and an `intermediate_session_token` will be returned.

SMS OTP factors can be used to fulfill MFA requirements for the target Organization if both the original and target Member have the same phone number and the phone number is verified for both Members.
Only Email Magic Link, OAuth, and SMS OTP factors can be transferred between sessions. Other authentication factors, such as password factors, will not be transferred to the new session.

To create a new member via domain matching, use the [Exchange Intermediate Session](https://stytch.com/docs/b2b/api/exchange-intermediate-session) flow instead.

Use this endpoint to exchange a Member's existing session for another session in a different Organization. This can be used to accept an invite, but not to create a new member via domain matching.

An object with the following fields:
== Returns:

The type of this field is +String+.
The `project_id` to get the JWKS for.
project_id::
== Parameters:

If you're using your own JWT validation library, many have built-in support for JWKS rotation, and you'll just need to supply this API endpoint. If not, your application should decide which JWKS to use for validation by inspecting the `kid` value.

If you're using one of our [backend SDKs](https://stytch.com/docs/b2b/sdks), the JWKS roll will be handled for you.

JWTs have a set lifetime of 5 minutes, so there will be a 5 minute period where some JWTs will be signed by the old JWKS, and some JWTs will be signed by the new JWKS. The correct JWKS to use for validation is determined by matching the `kid` value of the JWT and JWKS.

JWKS are rotated every ~6 months. Upon rotation, new JWTs will be signed using the new key set, and both key sets will be returned by this endpoint for a period of 1 month.
