  2. I get the following error.
    The specified segment is invalid: visitorid is expected to be a 16 hex charg string
  3. I think the URI is too long.

Is there a way to extend the limit or work around the problem?

2

Maybe if you can POST the parameters in the HTTP body instead of the HTTP querystring? (but I don’t know how)
I think also, for future data, you could use a custom visit dimension in order to be able to create a segment based on a simple parameter instead of having thousands of conditions…

3

Do you get an error because the URL is too long?

4

Probably the URL is truncated…

5

After I set 200 Visitor IDs in the Segmentation API, I can’t overwrite the condition settings in the Segment GUI with the same error.
I wonder if I can overwrite it because there are too many condition settings.
Please tell me the upper limit of the number of conditions in the Segment GUI.

6

It is recommended to not exceed 2000 characters long

As previously said, I think create such segment is not the good way…
You should add a dimension during tracking (eg. user-category), then the semgnetation will be easy and efficient.

If you can’t delete the segment through the API, you can try to logically delete it directly in the database (column deleted):
