Use to change copy or delays on a live sequence without disturbing people mid-journey. # Surgically edit steps — update content/delays, append, remove (any status) ## OpenAPI ````yaml patch /sequences/{sequenceId}/steps 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: patch: summary: >- Surgically edit steps — update content/delays, append, remove (any status) description: >- One transactional batch of typed edits. Execution order is fixed: removes (highest index first), then appends, then updates — indices address the array AFTER earlier phases of the same batch. Content/delay updates are allowed on any step (people already past it keep what they received); append is always allowed (completed people do not revive); remove is refused for any step somebody already reached. Any illegal edit rejects the whole batch, named by its position. operationId: editSequenceSteps parameters: - schema: type: string format: uuid pattern: >- ^([0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[1-8][0-9a-fA-F]{3}-[89abAB][0-9a-fA-F]{3}-[0-9a-fA-F]{12}|00000000-0000-0000-0000-000000000000|ffffffff-ffff-ffff-ffff-ffffffffffff)$ in: path name: sequenceId required: true description: The unique identifier of the sequence requestBody: required: true content: application/json: schema: $ref: '#/components/schemas/EditSequenceStepsDto' responses: '200': description: Default Response content: application/json: schema: $ref: '#/components/schemas/SequenceDto' '500': description: Internal Server Error content: application/json: schema: $ref: '#/components/schemas/ErrorDto' components: schemas: EditSequenceStepsDto: $schema: https://json-schema.org/draft/2020-12/schema $id: '#/components/schemas/EditSequenceStepsDtoInput' type: object properties: edits: minItems: 1 maxItems: 50 type: array items: oneOf: - type: object properties: op: type: string const: update step_index: type: integer minimum: 0 maximum: 9007199254740991 content: description: >- New content for the step.
