Changelog

This page documents all significant changes to the Invoicetronic API. Versions follow Semantic Versioning.

v1.0.15 - December 6, 2025

New Features

Invoicetronic-Version Header

Added Invoicetronic-Version header to all API responses. Clients can now verify the API version and detect updates by reading this header from any response. The version number matches the API release version (e.g., "1.0.15").

v1.0.14 - December 6, 2025

Bug Fixes

Webhook - Payload Encoding

Fixed webhook payload encoding from UTF-16 to UTF-8 for correct HMAC signature verification. The webhook HTTP payload was being sent with Encoding.Unicode (UTF-16LE) while the HMAC signature was computed using ASCII encoding, making it difficult for clients to verify the signature. Now both payload and HMAC computation use UTF-8 encoding, which is the standard for JSON payloads and ensures consistent signature verification.

v1.0.13 - December 5, 2025

Bug Fixes

Webhook - Wildcard event support

Fixed support for the wildcard event (*) in webhooks. Webhooks configured with the * event were accepted during creation but were never triggered. Now webhooks with * in their events list are correctly triggered for all events.

SDK v1.1 / API v1.0.12 - December 4, 2025

New Features

Webhook - resource_id field

Added resource_id field to webhook notifications. Webhook payloads now include the ID of the resource created or modified by the request.

For example, for update.add events, the resource_id field contains the ID of the newly created Update entity. This allows webhook receivers to directly fetch resource details without having to match based on timestamps or other heuristics.

v1.0.9 - December 4, 2025

Bug Fixes

Webhook notifications for receive.add and update.add

Fixed an issue that prevented webhook notifications from being sent correctly for receive.add and update.add events. Webhooks are now correctly triggered for the resource owner.

v1.0.7 - December 3, 2025

Bug Fixes

Webhook notifications with null company_id

Fixed an issue that prevented webhook notifications from being sent when the API response contained a null company_id value. Webhooks are now correctly sent even in these cases.

SDK v1.0 / API v1.0.0 - July 14, 2025

New Features

First official release of Invoicetronic API with full SDK support for 8 languages: C#, Python, PHP, Java, JavaScript, Ruby, Go, TypeScript.
