5.1.Web Services

The following points apply to the tables included in Sections 5.1.1-5.1.6.

The “Permitted Authority” column lists the authorities who are permitted to make the request. If any authority makes a request they are not permitted to make, they will receive an “Unauthorised” error (see Section 5.7 for a full list of error responses).

The “Input” column refers to various Entities and Components; these are defined via the schemas included in Sections 5.5.1 and 5.5.2.

Where available, a specific transaction should be used to update data rather than a general update. For example the Update(lifestate) transaction should be used to update the lifestate for a dog, rather than the Update transaction for a dog.
