Categories and figures

PATCH/v1/categories/{id}

Rename a category, change the settings its figures use, or both.

What it does

A new name needs the shops ability; settings need the sheet ability. Send the updatedAt you read, or the same time in an If-Unmodified-Since header, and the change is refused with 409 when somebody changed the category after it. After a change the figures are worked out again at once, as they are in the app.

Who may call it

A key whose maker's role holds sheet (edit the sheet and upload a report), after the fence, for the shop or category it names. Some uses also need shops (open, rename and archive shops, and connect their systems): the description above says which.

Errors

A refusal is JSON with a code, a sentence in error, and a requestId when the fault is ours. Read the code, not the sentence. Every code is listed on Errors.

StatusCodeWhenWhat to do
400api.invalidA path id, a query parameter, a header or a body field is missing or not valid. detail names the field.Read that endpoint in the API reference, correct the field and call again.
401api.key_missingThe call had no Authorization header.Send the key in the Authorization header as Bearer, then call again.
401api.key_refusedThe key is wrong, revoked, past its end, or its maker or company no longer allows it (developer mode off, the maker removed or switched off, or the maker's role lost the developer ability).Ask the person who gave you the key to make a new one.
401api.wrong_key_kindThis key does not open these endpoints.Use the key these endpoints were made for, or ask the person who gave you the key.
403refusedThe key's maker may not do this here: their role lacks the ability, or the shop or category is outside their reach.Ask the CEO for a role that allows it, or call it for a shop or category the role reaches.
403auth.not_freshThis step needs you to prove it is you.Confirm your password or passkey, then try again.
403refused.demoThe key belongs to a shared demo account, which may not change anything.Use a key made in a real company account.
404not_found.saidNothing with that id in the key's company. An id of another company answers the same.Check the id. List the shop or category it belongs to and take the id from there.
409report.noneThere is no report yet to work from.Upload a report first, with POST /v1/shops/{id}/reports.
409api.staleThe category changed after the updatedAt you sent.Read it again, then send your change with the new updatedAt.
429api.rate_limitedThe key made more than 120 calls in this minute. Wait the seconds in Retry-After.Wait the seconds in Retry-After, then call again.
500serverSomething failed on our side. The answer carries a requestId to quote.Try again in a minute; if it keeps happening, report it.
503developer.unavailableAPI keys are not set up on this deployment yet.Report it, and we will switch them on.
