Query isolines

After you receive your isoline ID through the isoline mutation, you can query your isoline. This isoline will contain polygons with the coordinates to render each layer. The amount of polygons is equal to the polygon_count that was set in the isoline mutation.

Query

To query the isoline details, you will need to configure it with the isoline ID. Be sure to include the status in your response and check it. If your isoline hasn't completed processing yet, then your isoline will not be available. To prevent this from happening, you can use the subscription service.

Please keep in mind that isoline mutations can take longer to process. The time is dependent on the range of the vehicle and the amount to which the polygon_count has been set.

Polygons

The amount of polygons is equal to the polygon_count. Every polygon consists of an index and a set of coordinates. This allows you to build beautiful front ends.

Response

A response can either contain a data or an errors object. The response header will always return 200 as a status code.
