Preventing Unauthorized Access: Ensuring that only authorized applications and users can access the marketing data. Maintaining Trust: Secure APIs help maintain the trust of your customers by protecting their data from being compromised. Avoiding Financial Loss: Security breaches can lead to significant financial consequences, including fines and loss of revenue.
