List SOPs
The workspace's standard operating procedures, most recently updated first — drafts and archived ones included, with status saying which. Summaries only: fetch one SOP to read the steps of the version in force.
https://app.xplantpro.com/read:sopsEditing an SOP moves it to the front of the list, so an SOP edited while you page through can move between pages: it may appear twice, or not at all.
Query parameters
| Name | Type | Required | Description |
|---|---|---|---|
limit | integer | No | Page size. Values above 200 are capped at 200. Default 50. From 1 to 200. |
offset | integer | No | Number of records to skip. Prefer cursor where a list offers it: an offset shifts when records are added ahead of it. Default 0. At least 0. |
cursor | string | No | Continue from the previous page: pass its meta.next_cursor unchanged, with the same filters. Treat it as opaque. Not combinable with offset. Up to 2048 characters. |
Example
curl "https://app.xplantpro.com/api/v1/sops?limit=50" \

200 with { "ok": true, "data": … }. data is an array. To get the next page, pass meta.next_cursor back as cursor; it is null on the last page. See Pagination.

|---|---|---|---|
next_cursor | string | null | Yes | Pass as cursor to fetch the next page. null means this is the last page. |

Errors
| Status | Code | When |
|---|---|---|
401 | UNAUTHORIZED | The key is missing, malformed or revoked, or its owner is no longer a member of the workspace. |
402 | PAID_PLAN_REQUIRED | The workspace's plan does not include the API. The full API is included with xPlant+ Teams and Enterprise; on Hobby and Pro Lab, keys can connect devices only. |
403 | FORBIDDEN | The key lacks a scope this operation requires, or its owner's current role in the workspace cannot use it — a key never does more than its owner can in xPlant. error names the scope, and for a role, the role it needs. |
403 | DEVICE_TOKEN_NOT_ACCEPTED | A device token was sent; this operation needs a workspace API key. |
422 | VALIDATION_ERROR | Both cursor and offset were sent; use one. |
422 | INVALID_CURSOR | The cursor is malformed, or came from a different list or different filters. Start again without it. |
429 | RATE_LIMIT_EXCEEDED | Too many requests for this key, device token or workspace. Wait Retry-After seconds. |
500 | SOP_QUERY_FAILED | The SOPs could not be read. Retry later. |
Branch on code, never on the error text. See Errors.
Record a step measurement
Records a numeric reading against one step of a run — the pH of a medium, the mass of an ingredient, a temperature — with its unit, as the bench station running the SOP reads it from a balance, pH meter or probe.

One SOP and the version the lab works from right now, with its steps — what a bench station shows the person at the hood.
