Plaid has introduced the ability to set distinct API secrets for different environments, namely Sandbox, Development, and Production, enhancing security and access control across organizations. This new feature allows development teams to have full access to the Sandbox environment without compromising security in other areas. To facilitate a smooth transition, Plaid has automatically duplicated existing API secrets across these three environments. Users are encouraged to sign into the Plaid Dashboard to update their API secrets and leverage this improved security measure.
