REST_API - Missing or invalid default region

Hello!
Sending SMS via REST_API works fine if you log in directly to kalkun before that. But, if this is not done, the request leads to an error.

An uncaught Exception was encountered

Type: libphonenumber\NumberParseException

Message: Missing or invalid default region.

What is the exact URL you use (with parameters) for the REST call?

You must use a phone number in international format when using REST api. Since the Region set in the settings is user dependent, and since indeed you cannot be logged in when using REST, the phone number must be in international format (leading + with country code, like +111111111). Maybe that's the problem.

// Default value to '' for the case this is called through Daemon or API

Kalkun/application/helpers/kalkun_helper.php

Line 358 in b18e4fe

// This way, we consider number is already in international format.

Yes, I know, and I use the number in the international format.

By the way, if I log in to kalkun before using REST_API, then in the xml response I see a number not in international format.

I updated the wiki https://github.com/kalkun-sms/Kalkun/wiki/Plugin:-REST-Api
Please follow it again and tell me if that fixes your issues.

Thank you for the tip. The issue was fixed.
