postBody property
If the user is signing in with an authorization response obtained via a previous CreateAuthUri authorization request, this is the body of the HTTP POST callback from the IdP, if present.
Otherwise, if the user is signing in with a manually provided IdP
credential, this should be a URL-encoded form that contains the credential
(e.g. an ID token or access token for OAuth 2.0 IdPs) and the provider ID
of the IdP that issued the credential. For example, if the user is signing
in to the Google provider using a Google ID token, this should be set to
id_token=[GOOGLE_ID_TOKEN]&providerId=google.com, where
[GOOGLE_ID_TOKEN] should be replaced with the Google ID token. If the
user is signing in to the Facebook provider using a Facebook
authentication token, this should be set to
id_token=[FACEBOOK_AUTHENTICATION_TOKEN]&providerId=facebook.com&nonce= [NONCE], where [FACEBOOK_AUTHENTICATION_TOKEN] should be replaced with
the Facebook authentication token. Nonce is required for validating the
token. The request will fail if no nonce is provided. If the user is
signing in to the Facebook provider using a Facebook access token, this
should be set to
access_token=[FACEBOOK_ACCESS_TOKEN]&providerId=facebook.com, where
[FACEBOOK_ACCESS_TOKEN] should be replaced with the Facebook access
token. If the user is signing in to the Twitter provider using a Twitter
OAuth 1.0 credential, this should be set to
access_token=[TWITTER_ACCESS_TOKEN]&oauth_token_secret=[TWITTER_TOKEN_SECRET]&providerId=twitter.com,
where [TWITTER_ACCESS_TOKEN] and [TWITTER_TOKEN_SECRET] should be
replaced with the Twitter OAuth access token and Twitter OAuth token
secret respectively.
