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

offset=0

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:

 

http://api.gbif.org/v1/occurrence/search?offset=1&limit=30

 

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?

 


Thanks,
