Google's OAuth requirements have undergone significant changes to enhance user data security, necessitating third-party apps accessing Google user data to undergo a verification process, especially if they use sensitive or restricted scopes. Apps with restricted scopes must also complete a security assessment, which can be costly and time-consuming, ranging from $15,000 to $75,000 and taking weeks to months. Exemptions from app verification exist for small-scale apps or those used within specific organizational settings. Nylas offers services to expedite the process, leveraging partnerships with security firms to ensure compliance with Google's policies efficiently and at lower costs. Their expertise helps developers navigate the approval process, allowing for quicker integration of Google services into their applications.
