Verify PIN

Use this method to verify the PIN code provided by a user. Submit the number (msisdn) along the PIN code that was previously delivered to them via SMS with the 'Request' method to verify against our records.

In order for verification to succeed, you must provide a valid MSISDN-PIN pair that has not expired nor exhausted its allowed maximum validation attempts, as per the settings specified with the 'Request' method.

If verification fails a number of times greater than was specified with the max_tries setting (3 by default), the PIN code wil be rendered invalid.



api_key Your API Key.
msisdn A mobile number that has previously requested verification.
pin The verification pin received by the user.

status Final request status - either "ok" or "error"

In case of status being "ok", result will contain details about the operation

verifiedtrue or false
previously_verifiedOnly if verified is true. Indicates whether the PIN has already been verified at least once.
tries_remainingOnly if verified is false and the max_tries setting is not 0. Indicates the number of attempts remaining to verify the specified msisdn.
messageA human readable message explaining the obtained result.
error_id In case of status being "error", this param will contain the error id.
error_msg In case of status being "error", this param will contain additional information. Should only be used for debugging.
200 OK
	"message":"PIN code verified."
User successfully verified
200 OK
	"message":"Invalid PIN code."
Unsuccesful verification. 2 Tries remaining.
