Authentication Overview

The Messenger API supports two primary authentication methods to accommodate different integration scenarios.

Authentication Methods​

Partner Authentication​

API key and Customer ID issued specifically for your partner organization. This single set of credentials is used for all API operations across multiple customers.

Use when: You're a third-party partner managing communications for multiple organizations.

Customer-Specific Authentication​

API key and Customer ID issued on a per-customer basis to the integrator. Each organization you work with has unique credentials.

Use when: You're integrating directly with individual organizations or need customer-specific access controls.
