SMS OTP

Our SMS APIs allow the sending of an SMS one-time code to a user, then obtaining that code for verification.

Note: Phone numbers need to be in E.164 format, ie. +14165551234

If they are not, you will receive a 400 error when making an SMS Send call.

Note: We only support US mobile phone numbers, any other country or phone type will be rejected and you will receive a 400 error.

{
    "phoneNumber": "+14165551234",
}
curl --location --request POST 'https://api.ratio.me/v1/auth/otp/sms:send' \
--header 'Authorization: Bearer eyJ......' \
--header 'ratio-client-id: <YOUR_CLIENT_ID>' \
--header 'ratio-client-secret: <YOUR_CLIENT_SECRET>' \
--header 'Content-Type: application/json' \
--data-raw '{
    "phoneNumber": "+14165551234"
}'

Once you receive the one-time code from the user, send it as well as the phoneId you received in the first response to the sms:authenticate endpoint to obtain a JWT.

{
    "phoneId": "phone-number-test-01234abc-0000-0000-0000-0123456789",
    "otp": "123456",
}
curl --location --request POST 'https://api.ratio.me/v1/auth/otp/sms:authenticate' \
--header 'ratio-client-id: <YOUR_CLIENT_ID>' \
--header 'ratio-client-secret: <YOUR_CLIENT_SECRET>' \
--header 'Authorization: Bearer eyJ......' \
--header 'Content-Type: application/json' \
--data-raw '{
    "otp": "123456",
    "phoneId": "phone-number-test-01234abc-0000-0000-0000-0123456789"
}'
