Requested waypoint parameter could not be matched

How to
1

Hi,
I am performing the following steps to get the toll amount.

  1. Pass origin and destination in Google Directions API request and retrieve a polyline from the response.
  2. Pass the polyline to Match API request and get the toll details from the response.

However, I receive the following error for some polylines when performing #2 above. Really hoping I could get some help…!
{
** “error”: “Requested waypoint parameter could not be matched.”**
}

Hi Vipul,

Are you able to share the polylines where the error is occurring?

Thanks Jaxeeno for looking at this.
Here’s the polyline from google.

Looks like there’s a mismatch between the road network in Google Maps and OSM which is causing some issues with snapping/matching to the road network.

You can use the accuracy field (a value of 15 seemed to work) to reduce the snapping constraint.

Woohoo… accuracy worked perfectly jxeeno.
Great help mate… thank you so much :slight_smile:

I’ll try few other polylines and see how it goes…!
Is “accuracy” defined in percentages? What other values could I use!! And is lesser the better or the other way??
Thanks heaps.

Notes: Strange that the Match API documentation does not mention anything about “accuracy”!!!

Thanks for letting us know. We have updated the documentation.

Excellent.
