Release notes

Sourced from sms77/api's releases.

• SubaccountTransferCredits

New Features

• ApiException class: Comprehensive exception for all API error codes (100-903) with descriptive messages
• Configurable test recipient: Tests now support SEVEN_TEST_RECIPIENT environment variable

Improvements

• Type safety: All Resource classes now use explicit type casts for consistent data handling
• Better error handling: Client now properly handles numeric API responses and throws appropriate exceptions
• Test infrastructure: Refactored BaseTest to AbstractTestCase for better test organization

Documentation

• Updated README with API error codes table
• Documented exception handling patterns
• Updated PHP requirement to 8.2+ in documentation

Breaking Changes

None - this is a fully backwards-compatible release.

v8.0.1 - Fix HLR Lookup Type Mismatch

🐛 Bug Fix

Fixed HLR Lookup Type Error

Problem:

• HLR lookup was failing with TypeError: Cannot assign int to property LookupHlr::$gsmCode of type ?string
• This occurred after the seven.io API was updated to consistently return gsm_code as integer instead of string
• Affected users on PHP 8.2+ with strict type checking

Solution:

• Changed LookupHlr::$gsmCode property type from ?string to ?int
• Updated getGsmCode() return type accordingly
