[noff]

Hello. Trying to update user screen_names by their ids.

Making this request:

Got 404 error.

Tried to reduce length of request and leave only one user id:

GET /1.1/users/lookup.json?user_id=182786667 HTTP/1.1

Got save error.

When making request with screen_names, all works great. By I have not screen_names - I trying to define it after /friends/ids.

Is there any solutions except using /users/show (it will use too many requests to API).

For the 2nd case, you get a 404 because there is no user with the ID “182786667”

For the first case, either all the users you are enumerating are non-existent OR perhaps you’re library is overly-encoding those commas and you’re actually sending one very long value to as the user_id

Yes, I found that user with ID 182786667 do not exists (but I’m sure I’ve imported this number with friends/ids).
But is it possible to get info about users, who exists, from all array of IDs? I send 100 ids and only one non-existent ID break all request, and I do not know, which ID break it.

[noff]

I understand reason of error.

When I send to API 100 ids, it returns all found users. If 1 of user do not exists, it returns array of 99 users.

And yes, there are only not-existent users in my queue and twitter return not an empty array, but 404 error page. It is not very clear, but OK, I found what to do next. Thanks for this:

“either all the users you are enumerating are non-existent”
