I'm using the Google Place API for place search:
https://developers.google.com/places/documentation/search
After the first query of the api, I'm getting the next page by setting the pagetoken. If I wait 2 seconds between requests, it works, but I notice that if I make the next query right after the previous one, it returns the status INVALID_REQUEST.
Is this some kind of rate limiting? I don't see this anywhere in the documentation.
https://developers.google.com/places/usage
Since each request has 20 places, getting a list of 100 results will take over 10 seconds which is a long time for someone to wait using an app.
It is documented, see the documentation
By default, each Nearby Search or Text Search returns up to 20 establishment results per query; however, each search can return as many as 60 results, split across three pages. If your search will return more than 20, then the search response will include an additional value — next_page_token. Pass the value of the next_page_token to the pagetoken parameter of a new search to see the next set of results. If the next_page_token is null, or is not returned, then there are no further results. There is a short delay between when a next_page_token is issued, and when it will become valid. Requesting the next page before it is available will return an INVALID_REQUEST response. Retrying the request with the same next_page_token will return the next page of results.
