Verify that calls to HDC charts are using WFP API Gateway

Provide a clear and concise description of what you want to happen.

I think we might have two different approaches to get chart data from the HDC stats API. It seems that if you use tooltip pathway, we use a get request using the config in layers.json (ex: api.earthobservation.vam.wfp.org/stats) while the charts panel uses the HDC stats api url configuration from the PRISM backend.

We should use the PRISM backend for both cases so that we're using the HDC token.

I tried removing "url": "https://api.earthobservation.vam.wfp.org/stats/admin/fetch", within chart_data for the blended rainfall layers (this config wasn't present in other layers with a chart - only blended). When I remove it, fetching chart data fails both in the tooltip and in the chart panel.

It looks like vam=rfb isn't handled in the PRISM backend. This blended layer query fails: https://prism-api.ovio.org/hdc?level=2&admin_id=1010621&coverage=full&vam=rfb&start=2023-02-11&end=2024-02-11

While this 'non-blended' query works fine: https://prism-api.ovio.org/hdc?level=2&admin_id=1010621&coverage=full&vam=rfh&start=2023-02-11&end=2024-02-11

Is there anything else you can add about the proposal? You might want to link to related issues here, if you haven't already.

It looks like the issue is that the WFP Gateway doesn't support vam=rfb.

@valpesendorfer - are you planning to add blended data access to the WFP API Gateway?

If that was supported, I think simply removing the url parameter from chart_data in layers.json would work as expected.

[valpesendorfer]

yes the blended data will be added to the API served through the WFP API gateway - probably first in dev and then rolled over to prod.

No longer needed as the API Gateway approach has changed
