Hosted KYC/KYB: Parameter to preset the session language
The IdentityVerification object now supports session_language (SessionLanguage), the initial language of a hosted identity verification session created via POST Create an IDV Session. The value isn’t returned in the API response, but adds an lng query parameter to HostedUrl.
If not set, the session takes the language of the user’s browser (if supported), or otherwise English. The user can also change the language from within the session. Read more about hosted KYC/KYB session language →
Changed
Sandbox credentials for the test suite are now required environment variables
If you clone the SDK repository to run its test suite, you now need to set Sandbox credentials as environment variables:
MANGOPAY_CLIENT_ID– Your SandboxClientIdMANGOPAY_CLIENT_PASSWORD– Your Sandbox API key
There is a second set of variables for the token-isolation test. The suite fails with a clear error if any required variable is missing.
