no api-key error massage - javascript

I have tried many ways and many places to enter the API key for but in all the cases, I get the error no-API-key. the request works fine in the postman, meaning the key works fine.
the places I tried:
where I mentioned in this code
at the end of snap to road request call
at the end of all the request calls

Leaflet Markers + clustering terribly slow, jsfiddle demo(200-400 markers)

here is my script, I'm currently having a bad time with leaflet, it is taking substantial amounts of time to load my markers yet I'm only playing with up to 200-500 at a time and can't seem to find the reason why.
Markers are pulled from an API and stored into an array then plotted onto the map upon clicking a section on the map, see for yourself on the live demo, it works fine until loading markers then it starts to lag a lot when zooming
If anybody has a solution for me it would be much appreciated as I intend to have a lot more markers than it is currently pulling.

Google Maps API v3 - Directions with draggable alternate routes

I've successfully implemented google map direction service api : https://developers.google.com/maps/documentation/javascript/directions with 'draggble' option enabled. Is it possible to show all routes together if multiple routes are available between 2 locations?
The current code is similar to: https://developers.google.com/maps/documentation/javascript/examples/directions-draggable and I do have alternative routes available in response code as I've enabled provideRouteAlternatives: true.
I tried the solution provided in : How to display alternative route using google map api. But when I used that code, I found it draws multiple routes with independent markers. That is, if 4 routes are available, there will be 4 'A' locations and 4 'B' locations and while dragging - only one of them get selected. Please find the below screenshots.
Initial View:
After dragging initial locations (issue with duplicate locations)
I need to drag in such a way that, when the location A or B is dragged, there should not be any duplicates and alternate routes should be automatically shown.
My current code is as follows (API key not added here):

Please help me. Thanks in advance!
Each route you draw is editable and has a start and end marker which means that you will always be dragging one of the routes marker and not all at once. You could use the suppressMarkers option to remove markers from the alternate routes but that wouldn't change a lot to the behavior.
The problem is that as each route is separate, if you move the start or end location, you should redraw every route otherwise only one will update.
That said, if you edit a route (other than by changing its start or end location) you should not redraw your routes. If you update the start or end location you will of course then lose any route waypoint you added. Unless you do something about that... which sounds like a pain.

set start and end position in google roads API using javascript

I want to know if setting start and end location in the map while I'm retrieving coordinates and placeId through google roads API is possible or not? Because while I initialize Roads API by setting a custom coordinate like:
var mapOptions = {
zoom: 17,
center: {lat: -33.8667, lng: 151.1955}
};
its shows me a specific location in the map where the coordinate exists. But I want to initialize a map where I set a start and end location in the map and then start to use snapToRoads API to retrieve coordinates.
Ok, I have done a little bit digging and solved it by myself.
