Update OpenAPI spec for ticket updated attribute metadata

[sametozcan]

We have added a new filed to Ticket Part to share the updated attribute data within the webhook response.

Are these arrays because attributes can be arrays? Or what's the reason?

[sametozcan]

Yes. There are different kind of attributes and the way we have the ID and label can slightly differe in different cases. See examples here

Mainly, file attributes can hold multiple files in a single attribute. That's the reason arrays are used there if the attribute is a file attribute.

[sametozcan]

In the case of an attribute is cleared,

• id can either be null or an empty array (for file attribute)
• label can either be an empty string or empty array (for file attribute)

[steve-henry]

Does the type field not change depending on if it's an array or single value? Or does the client need to check for array or single value each time?

[sametozcan]

Currently type only returns attribute. We can add some extra queries to find the actual type of the attribute and use that as the type so the client would know what to expect there.
Alternatively the client can query that separately if they want to know the type of the attribute for that ticket type.

[sametozcan]

Let's wait to hear from the customer so we can improve that furthermore.

Approving as this matches the current API behaviour.

Left one non-blocking question around array vs single value
