Here are some CURL examples, which will help you understand the REST API: 


  1. Request Verification Flashcall (Preferred flow without CLI return): (we can configure your account for returning the CLI to expect in the request http response, useful for matching OTP code without dependency on report step.)
     curl--user APPLICATION_KEY:APPLICATION_SECRET -H "Content-Type: application/json" --data "{'identity':{'type':'number','endpoint':'+1555123123'},'method':'flashcall'}"
    Sinch can configure the API to return the CLI on request (OTP Code).
  1. Report Verification Flashcall using Verification ID (no PI-data i URL): 
    curl -X PUT --user APPLICATION_KEY:APPLICATION_SECRET -H "Content-Type: application/json" --data "{'method': 'flashcall', 'flashcall': {'cli': 'OTPCODE'}}"
  1. Request Verification SMS (Default, documented flow): 
    curl --user APPLICATION_KEY:APPLICATION_SECRET -H "Content-Type: application/json" --data "{'identity':{'type':'number','endpoint':'+1555123123'},'method':'sms'}"
  1. Request Verification SMS with custom code (NON DOCUMENTED): 
    curl --user APPLICATION_KEY:APPLICATION_SECRET -H "Content-Type: application/json" --data "{'identity':{'type':'number','endpoint':'+1555123123'},'method':'sms','smsOptions':{'code':'123456'}}"
    Note: When the customer specifies their code, the report verification step is strictly not necessary but still desirable.
  1. Report Verification SMS OTP:
    curl -X PUT --user APPLICATION_KEY:APPLICATION_SECRET -H "Content-Type: application/json" --data "{'method': 'sms', 'sms': {'code': 'OTPCODE'}}"

Note: When using the REST API, Callbacks are not needed. Callbacks may be useful for tracking costs, but only if this is a direct customer request.
