Use to slow down or speed up one step; the first step always waits zero. # Change how long a step waits before it sends ## OpenAPI ````yaml patch /sequences/{sequenceId}/steps/{stepIndex}/delay openapi: 3.1.0 info: title: OpenCX API description: > OpenCX is an AI-powered, all-in-one platform for customer support and outbound communications. Use this API to manage your OpenCX organization's AI agents, actions, conversations, contacts, and more. To get started, generate a new API key from the dashboard. ## Authentication All API endpoints require authentication using a Bearer token. You can generate an API key from your OpenCX dashboard. ## Rate Limiting API requests are rate limited to ensure fair usage. The current limits are: - 100 requests per minute for standard endpoints - 1000 requests per minute for streaming endpoints ## Error Handling The API uses standard HTTP status codes and returns detailed error messages in the response body. version: 1.0-beta license: name: MIT url: https://opensource.org/licenses/MIT servers: - url: http://localhost:8080 description: Development - url: https://api.open.cx description: Production security: - bearerAuth: [] paths: /sequences/{sequenceId}/steps/{stepIndex}/delay: patch: summary: Change how long a step waits before it sends description: >- Minutes after the previous step — 30 for half an hour, 1440 for a day.
