[API-users] Get specific occurrences

Hi Akshat, the offset param defines how many items to skip before beginning to return rows. That means that to get the next page you have use offset=30 for your second request, in general you should use something like
first call: offset=1&limit=30
then: offset=(limit + previous offset)&limit=30

I hope this helps, Fede.

Subject: [API-users] Get specific occurrences

Hi all,
I'm trying to get all the years of occurrence for a specific organism.
I tried pagination and with the limit and offset parameters. For example:


But I noticed that each successive page has duplicate results. For example:
for the scientific name: Aaptos aaptos, I tried limit= 30 and increased the offset parameter as-

offset=0&limit=30 and offset=1&limit=30

The two queries have 29 common results.

Is this supposed to happen or am I doing something wrong?
