RE: HTTPAPI Question -- RPG400-L

"Link"

From debug:

HTTP/1.1 200 OK
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Content-Type: application/json
Date: Tue, 09 Jul 2019 19:30:18 GMT
Expires: 0
Link: <https://my_development_site.net/api/orders?max=10&offset=10>; rel="next"

So I will have to extract the link from between the "<>"

Yes, it sounds like http_header() is exactly what you need.

I've not heard of using the headers for this sort of thing before. Out of curiosity, what do they call the header with the "next link"?

No... In performing a GET (to get JSON order data), they return 10 orders... if there are more orders, they return "LINK" in the HTTP header with the URL to the "next 10" orders.

They call it "pagination".

I've never seen it done that way before - typically that kind of info is included in the JSON data.

The HTTP_HEADER() procedure works perfectly.

What do you mean by "next page information"?

Are you referring to a redirect, such an HTTP 302 or 303 code?

I'm working with a REST API that is returning "next page" information in the HTTP header (instead of in the JSON payload)... is there a procedure in HTTPAPI to retrieve that info?

Thx,
