I’m working on configuring SMS tokens. We have a custom endpoint setup that submits requests to Vonage’s API. When an SMS token is sent, what does the structure of the request look like? Is the phone number and text message contained in the body?
as a first source, you should consult https://privacyidea.readthedocs.io/en/v3.5/configuration/sms_gateway_config.html#http-provider. There are also examples given.
