insertSpaceTextLines

Insert lines into a text file by line number (from getSpaceTextLines), every existing line left exactly as it was (headings, an intro, a summary) as a new version, like a save. beforeLine 1 is the top, totalLines + 1 the end; several insertions before one line keep their order. Use it instead of saveSpaceTextFile whenever the file is too large to re-send whole.

Variables

The example sends only what the schema requires. Some operations also need one of several optional variables (one filter or another, say); the description above says which.

inputInsertSpaceTextLinesInput!required

itemIdID!required

baseVersionIdID!required

The versionId the line numbers were read from; refused if someone saved since.

insertions[SpaceTextLineInsertion!]!required

Every field, all the way down

Response

What comes back under data: a list shows as one entry, and a value as its type.

Errors

400unknown_variable

A variable the operation does not declare. A typo is refused rather than silently dropped.

401unauthorized

No bearer header, or the key is invalid or revoked.

403insufficient_scope

The key lacks the scope the operation requires.

403forbidden

A referenced record does not exist, was deleted, or is outside your organization. The gateway cannot tell those apart.

409idempotency_conflict

A request with this Idempotency-Key is still in flight.

Idempotency

Send an Idempotency-Key of 1 to 255 characters. A finished request retried with the same key replays its stored response, marked Idempotency-Replayed: true; one still in flight returns 409 idempotency_conflict. Keys expire after 24 hours. Write without fear →
