Any fields that are not provided are left unchanged. Omit `type` to keep the work entry at its current type. Provide `type` to convert the work entry, in which case the fields of the new type must be provided as well and the fields of the previous type are discarded. Only fields belonging to the resulting type may be sent. Work entries that have already been billed can still be edited, but this does not change any invoice that was already issued from them. ## Modifying a work entry Any fields that are not provided are left unchanged. Omit `type` to keep the work entry at its current type and correct individual fields: ```json theme={null} { "hours": 4, "minutes": 15 } ``` Provide `type` to convert a work entry into another type. The fields of the new type must be provided as well, and the fields of the previous type are discarded: ```json theme={null} { "type": "fixed-price", "price": 50000 } ``` Only fields belonging to the resulting type may be sent. Sending a `price` for an entry that stays `hourly`, for example, is rejected with `general/malformed-request`. Work entries that have already been billed can still be edited, but this does not change any invoice that was already issued from them. The `wasBilled` field is read-only and is set by Infinity when the work is billed. ## OpenAPI ````yaml PATCH /v1/projects/{projectId}/work-entries/{workEntryId} openapi: 3.1.0 info: title: infinity.swiss Open API version: '1.0' summary: '' servers: - url: https://api.infinity.swiss security: - apiKey: [] paths: /v1/projects/{projectId}/work-entries/{workEntryId}: parameters: - schema: type: string name: projectId in: path description: The id of the project the work entry belongs to. required: true - schema: type: string name: workEntryId in: path description: The id of the specific work entry. required: true patch: tags: [] summary: Modify work entry description: >- Edits the provided fields of a work entry.
