Dynamically set Google Maps API key in Xamarin forms - google-maps

I am working for a product based company. We are building Xamarin form apps for our customers. We would like to have separate Google Maps API key for our customers. But as per the documentation this can only be done in Manifest files.
We would like to set this key dynamically, as our app is available on Play Store and based on customer, we will decide the key.
Kindly let me know how can we achieve this.

One thing you can do is to have a "tag" for each of the customers and call google analytics at the same time that you are calling the Google Map.. Then you can run a report on Google Analytics based on the tag

Website Restrict Google Maps API key dynamicly via SDK

my question: Is there any Google API / SDK I can use to be able to dynamically add "HTTP referrers (web sites)" (assign domains) to maps API key ?
Background
I'm building a web-application portal that will allow anyone to create a business website and assign a custom domain to it.
On that generated website customer will have google maps map pointing to address of their business.
Customer has an option to add custom domain to their business website created by my web-application (by CNAME to the my web-application)
Desired feature is that once the domain background job will get triggered that will add that domain/host to list of restricted domains/hosts for my Google Maps Api key so that their domain will be able to read google maps on their domanin
note: I Have cron job DNS lookup validation check implemented to ensure that domain is really assigned to the domain
live example
here is website generated by customer on my web-application http://sbs-sos.sajtka.sk/ he assigned a domain and pointed CNAME http://sbs-sos.sk/
Reason why the google map works is because I manually white-listed their domain. I need to automate this
please aware portal is not fully launched so many bugs are happening
The feature request to manage API keys restrictions via SDK was submitted in Google issue tracker in 2016:
https://issuetracker.google.com/issues/35829646
Currently, there are no any official SDK for that. However, the last update from Google says that they released experimental API to programmatically manage your API Keys and their restrictions.
The best way to handle thousands of authorized domains is to use an API to programmatically manage your API Keys and their restrictions, and we have recently launched a new service that allows you to do this.
This API is still in Alpha. If you are interested in becoming a Trusted Tester for this service, you can use the following form to sign up, please read the instructions carefully:
https://forms.gle/qx2SMcarWCAsbWVp7
Please note that this API is not part of the Google Maps Platform. After you fill out the form, you will be contacted by the API Keys API team with instructions on how to get started, and how to receive support.
API Keys API is currently free of charge. However, please note that use of Cloud Endpoints may be subject to charges at high traffic volume. You can check the pricing sheet here:

I would suggest joining Trusted Tester program and try out this API.
I hope this helps!

Google API key Vs. Google Client ID

One of our customers is using google maps with a "Client ID". We've developed our product using the Google API Key. All of the features of the map are working properly using the API key, but we are unable to confirm that the client will get the same results with the Client ID since we do not have one. Two question, do you believe that the features will work the same using either the API or the Client ID? Second question, how much does it cost to purchase a Client ID?
Client IDs and API Keys are forms of authentication and authorization. There are easy-to-follow guidelines on their proper usage and their limits. Everything you need to know about them can be found in the documentation (also try seeing the docs per product in the 'For more information' section):
https://developers.google.com/maps/premium/overview#authentication_and_authorization
Related SO post and answer about using Client IDs for their Javascript API:

For pricing, read more about it here:
https://developers.google.com/maps/pricing-and-plans/
EDIT: There has been recent Google Maps Platform pricing and product changes You'll always need an API key and a valid billing account associated to your Project if you want to use the Google Maps Platform APIs. If you've never had a Client ID then you don't need to worry about it, just continue using your API keys.
You may run into some APIs (i.e. Speed Limits API) that seem to need a Premium Plan account. If you really need access to these, simply contact sales using this form.
P.S.
When using API keys, be sure to properly restrict them!

Can a Single Key (Bought From Google) work for all applications

So, I have bought a key from google for translation; I'm using it and it works as expected. Now there 's another requirement from client to use google maps in his application. Should I have to buy another key for the google map application, or is there anything like a master api key which'll work for all google applications?
Different APIs have different requirements for monitoring and managing usage. Depending on your use case you may or may not have to pay for using Google Maps. And no, there is no master API key that gives you access to all Google APIs.

Google Maps API Key - Get one for everyone of my users programmatically?

I saw that one has not to obtain a Google Maps API key if you want to use their maps api in general, only if you want to use their web services and statistics etc.
Now I have two questions regarding this:
If I have a public website which uses the Google Maps API to display a map with default options. How does Google count the API calls if I don't use an API key? (Maybe with the help of the domain which requests the map?)
If they do so and my site exceeds the 25k calls/day, is there a possiblity that my users can login with their Google account on my site and some backend logic will get them an API key from Google that I store e.g. in a database. So I could use the API keys of my users to bypass the API usage limits only for my site.
Assuming you are using the Javascript API v3:
This SO question partially answers your queries.
Have a look at the usage limits, it looks like that you cannot use more than one API key:
Can I use more than one API key to increase my available usage over
the documented limits?
Google reserves the right to withhold access to the Maps API from any site that attempts to use more than the permitted number of map
loads of the Maps API without permission, and fails to respond when
contacted by Google.
Though this may be debatable, to me it seems a bad idea using your user's API key. For sure you need to ask the permission, then you have to monitor their quotas and so on, a minefield...
TL;DR if you exceed constantly the daily quota you should purchase a larger quota.

Google map on Customers website

I have build few websites with google maps before 2012. But in 2012 google have made few changes and I'm confused what procedure should I follow in order to add Google map to new website.
I'm building websites for customers so how should I obtain API key? Everywhere I look there are only answers to questions like "How to add Google map to my website?". I don't want to add map to my website. I want to add map to my customer website.
Every API Key is now linked to google account so I can't use my API key as this may lead to exceed my usage limit.
First of all is not mandantory to obtain a key for your map to function.
In case your app exceeds the usage limits only then you have to take further actions.
If you want to monitor the usage create an account for your customer and obtain a key just for him.
