Get All Alerts

[CoryatJohn]

I would like to pull all the alerts in a single query to populate the alert system in our application. Right now, I see around 350 active alerts and there's little weather. I can see alert counts going above 500. I tried using the limit=1000 parameter and it was rejected. The documentation says 500 is the default. The error code says 500 is the maximum.

So how do I pull the entire list of alerts? It's not an issue if it takes several requests but it does make it more complicated.

Thanks!

Edit: I may have found my own answer. Use a start time. I think this will solve it nicely.

Set the limit really low. You'll get a "pagination" property in the response. Follow the provided link.

Here's an excerpt from https://api.weather.gov/alerts?limit=5

  "pagination": {
    "next": "https://api.weather.gov/alerts?limit=5&cursor=eyJ0IjoxNzEzNjQ1MDAwLCJpIjoidXJuOm9pZDoyLjQ5LjAuMS44NDAuMC5kNWZjOThmYzU5ZmFmODcyZWZiMWJjMDg4YTM0NjllYjI4MmFlYzZhLjAwMS4xIn0%3D"
}

Perfect! Thanks!

Currently the limit applies to /alerts with a max of 500 (default). /alerts/active does not currently use the limit feature (it will return all active alerts even if more than 500 and the limit filter can't be used either).

When I request the alert list without a limit, I get 500 alerts and no pagination cursor.

As @sullynole noted, the full path to active alerts /alerts/active does not have a limit and will return all active alerts in one request. Using just /alerts with the parameter "active" might honor the limit request, but that would require multiple requests. Using the full path is recommended and supports the other parameters.

The URL: https://api.weather.gov/alerts returns exactly 500 alerts. It also has a pagination parameter, so I was incorrect in stating that.

Looks like the maximum is 500 no matter what. So using pagination along with a start date will certainly solve my issue.

Are you looking for all alerts, even expired alerts, or just active alerts?
