API changelog

Changelog

The changelog lists all updates to the Helcim API and our documentation in chronological order, from most recent to least recent.

Date	Tool	Change
2024-12-06	Documentation	Updated Payment API and Invoice API Guides.
2024-11-19	Payments	Successful test credit card payments on developer test accounts will now return a status of "APPROVAL" instead of "APPROVED". This change was made to align payment responses on test accounts with those on production accounts.
2024-09-23	Documentation	Added a changelog to document changes to the Helcim API and documentation.

Breaking changes

We endeavour where possible to ensure that all updates to the Helcim API and HelcimPay.js are backwards compatible. Where this is not possible, those changes will be documented under our Breaking Changes section.

The breaking changes log lists all updates to the Helcim API that would cause an integration with the Helcim API or HelcimPay.js to stop working.

Date	Tool	Change
2024-09-23	HelcimPay.js	Due to unintended data being returned in the HelcimPay response sent to the window object, we have removed the config.transitional.data element from the response. For merchants using this unintended data being returned, this would be a breaking change.
