🚧
v0.2 of Gamma's API offerings will be deprecated on Jan 16, 2026.
Please move to v1.0 of Gamma's API endpoints before this date to avoid disruption.

We highly recommend you read Understand How the API Parameters Work before delving into this page.

This page describes the list of parameters that help users define their gamma generations. For some parameters -- imageOptions.model and textOptions.language -- there is a long list of accepted values, which are listed respectively in the Image Model Accepted Values and Output Language Accepted Values sections.

Generated gammas appear in a separate tab in your dashboard. This tab appears only after you have successfully created at least one gamma using the API.
