Important Update on Developer Portal Functionality

Dear Valued Customers,

We hope this message finds you well. We would like to extend our sincere apologies for any inconvenience caused by the recent interruption in the functionality of our Developer portal.

Key Updates:

  1. Portal Interruption: We regret to inform you that our portal has been non-operational since November 3. However, we assure you that our API has continued to work seamlessly for all our customers during this period.

  2. Migration to a New System: Due to unexpected non-technical reasons, we have had to transition from our previous API management provider, Red Hat, to a self-managed system. This move was necessary to maintain the quality and continuity of our services.

  3. Restoration of Data: We have successfully restored all account data except for password information and account statistics. In light of this:

    • We kindly request that you use the password recovery function to reset your password before signing in.

    • If you encounter any issues during the password recovery process, please do not hesitate to reach out to us at Our team is on standby to offer prompt assistance and ensure a smooth transition for your account.

We understand the critical role our services play in your business operations. Our team is diligently working to ensure a seamless experience on our new platform and we appreciate your understanding and patience during this transition.

Thank you for your continued trust in our services. We are committed to delivering the high standard of service you expect from us.

Warm regards,
