Dear Cobo Users,

We are excited to announce the official launch of the WaaS 1.0 API key management feature on Cobo Portal, available starting November 19th, 2024. This feature can be accessed through the [Developer Console — WaaS 1.0 (Cobo Custody)] tab and can only be configured by admins.

The WaaS 1.0 API key management feature includes:

• Add new WaaS 1.0 API keys

• Edit WaaS 1.0 API keys

• Add and edit URLs for WaaS 1.0 API callbacks and set up transaction notifications

• View WaaS 1.0 API push history and resend API callbacks

Following this launch, the WaaS 2.0 tab of Developer Console will undergo the following adjustments:

• API key and callback data related to WaaS 1.0 API keys will no longer be displayed.

• Historical data for WaaS 1.0 API keys will remain accessible in callback messages, but any new data generated after the launch will not be shown.

• The WaaS 2.0 API key management functionality will not be affected.

If you have any questions, please feel free to contact us.

Cobo Support
