@rp_st I'm using passwordless recipe, i want to send another field value say 'role' from frontend to backend while submiting the OTP. I want that value to assign roles in supertokens

You can use the pre API hook on the frontend to set the custom attribute to the consume code API, and then read that on the backend by overriding the consumeCode API

Passwordless.init({ contactMethod: "EMAIL_OR_PHONE", preAPIHook: async (context) => { let url = context.url; let requestInit = context.requestInit; let action = context.action; if (action === "PASSWORDLESS_CONSUME_CODE") { context.userContext= { role: "client" } } return { requestInit, url }; } }),
