Convex Mutations API

  title: Convex Deployment Platform AccessTokens Mutations API
  description: The Convex Deployment Platform API is a deployment-scoped administrative REST API for configuring individual Convex deployments. It exposes private endpoints accessible only to deployment administrators and supports operations such as managing environment variables and other deployment configuration settings. Each deployment has its own endpoint in the format https://{deployment-name}.convex.cloud/api/v1/. Authentication requires an Authorization header using deployment keys, Team Access Tokens, or OAuth Application Tokens formatted as "Convex {token}". This API is currently in Beta and is intended for platform integrations and infrastructure automation workflows.

      summary: Execute a mutation function
      description: Executes a mutation function that performs transactional writes to the Convex database. The function is identified by its module path and export name.
