Vonage API Support Priorities, Hours, and Holidays


This article explains some key information about working with Vonage API Support. Refer to our About Support page for more information about our Support programs, including Service Level Objectives (SLOs).

We have these guidelines to help us provide the best possible support for our users, but we also try to be flexible when it's in our users' interest.

Support Priorities

The following table defines the criteria and examples for our support priorities. Every support request is important, but some will require Vonage API and our users to work with a greater sense of urgency. It's in our users' interest that we make good decisions about which requests require the most immediate response. We will assume that requests submitted by email are normal priority.

If you believe your issue meets the criteria for a different priority level, submit your Support request online, proposing the priority level.

Once our support engineers review your request, they may adjust the priority to the appropriate level, up or down.
