## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Query parameters

- `createdAt.gt` (string, optional) — Datetime, in RFC 3339 format. Time zone defaults to UTC. Restricts results to those created after the specified time. e.g. > 2017-04-30.
- `createdAt.gte` (string, optional) — Datetime, in RFC 3339 format. Time zone defaults to UTC. Restricts results to those created at or after the specified time. e.g. >= 2017-04-30.
- `createdAt.lt` (string, optional) — Datetime, in RFC 3339 format. Time zone defaults to UTC. Restricts results to those created before the specified time. e.g. \< 2017-04-30.
- `createdAt.lte` (string, optional) — Datetime, in RFC 3339 format. Time zone defaults to UTC. Restricts results to those created at or before the specified time. e.g. \<= 2017-04-30.
- `id.anyOf` (string, optional) — Restricts results to those matching any of the specified IDs. Comma-separated list.
- `nextToken` (string, optional) — Token for pagination
- `omit` (string, optional) — Comma-separated list of top-level fields to omit from each returned item. Cannot overlap with returning.
- `pageSize` (integer, optional) — Number of results to return. Defaults to 50, maximum of 100.
- `returning` (string, optional) — Comma-separated list of top-level fields to include in each returned item. Cannot overlap with omit.
- `sort` (enum, optional, default: createdAt:desc) — Method by which to order results. Valid sorts are: createdAt (created time, oldest first). Use :asc or :desc to specify ascending or descending order. Default is createdAt:desc.
  - Allowed values: `createdAt:asc`, `createdAt:desc`

## Types

### ProcedureFlowchartConfigVersion

Represents a snapshot of a procedure's flowchart configuration at a specific point in time. The flowchart defines the structure of a procedure as a directed graph, where nodes represent method steps (see `nodes` and `ProcedureMethodDefinitionVersion`) and edges define the execution order and dependencies between them (see `edges` and `ProcedureEdge`). This type is accessible from `Procedure` (via `latestProcedureFlowchartConfigVersion` and `publishedProcedureFlowchartConfigVersion`), `ProcedureRun`, and `ProcedureRunPlan` to provide a read-only view of the flowchart structure for execution and planning purposes. ## Product mapping - In the Benchling UI, this is the **flowchart version users are viewing** when they open the procedure graph for a procedure. - `nodes` correspond to unit operations (`ProcedureMethodDefinitionVersion`) and `edges` correspond to graph connections between those unit operations.

- `__typename` (string, optional)
- `createdAt` (string, optional)
- `edges` (list of ProcedureEdge, optional)
- `id` (string, optional)
- `nodes` (string, optional)
- `procedure` (ProcedureRef, optional)

### GeneralErrorDetail

### TooManyRequestsErrorBodyDetail

### InternalServerErrorBodyDetail

### ProcedureEdge

A directed connection between two nodes in a procedure flowchart. The edge's type (see `ProcedureEdgeType`) determines what `sourceId` and `targetId` reference: for METHOD_EDGE, they are method definition version IDs; for MATERIAL_EDGE, they are material version IDs. Edges define the structure and flow of a procedure's execution graph.

- `__typename` (string, optional)
- `sourceId` (string, optional)
- `targetId` (string, optional)
- `type` (enum, optional)
  - Allowed values: `METHOD_EDGE`, `MATERIAL_EDGE`

### ProcedureRef

- `__typename` (string, optional)
- `id` (string, optional)
