Google API and AppsScript - api

If I am using Google API (this one) to access a GoogleSheet document, do the calls I am making via an API have any impact on the AppsScript-specific URL Fetch Service quota mentioned here and here ?

No, I don't believe they do. 2 separate quotas.

Can BigQuery API Call use API Key of Service Account?

In google cloud I have a service account with big query access.
I would like to use API Key within bigquery api Request. Can this be done?

(Sorry, don't have enough reputation to comment) In general, you can use service account to authenticate when using BigQuery. The actual way to do this depends on the client you're using.

How to authorize google analytics API through API Key

I need to display the analytics of my site to all the users, but Using OAuth it displays the analytics of the sites configured for the logged in user. How can I implement a dashboard using embed API but showing my website analytics only?
The best possibility I can come up at is using API Key instead of Client ID, but I am unable to find a way to do it.
Does anyone have anything else in mind.
API keys are used for accessing public data, like the list of dimensions and metrics in the metadata API. In order to access private Google Analytics data you must use Oauth2.
So you don't want to use the API key, what you want to do is use a service account and then authorize the service account service-side, receive and access token from that authorization flow, and then pass that access token to the Embed API.
Here's a full working example:

What is the difference between the “Google+ API” and the “Google+ API (Sign-in)”?

What is the difference between the “Google+ API” and the “Google+ API (Sign-in)”?
The Google+ API (Sign-In) seems to be suited at allowing a developer to integrate the Google login in into their application to allow their app to have an OAuth token to interact with Google services.
The Google+ API on the other hand is just the Google API that allows access to a users Google+ API data, you will need an authentication token to access this data.
The two different quota buckets refer to two different subsets of the API that are available. You can see https://developers.google.com/+/api/#quota for the details, but broadly speaking:
The Sign-In portion applies to methods that specifically need the plus.login scope. These include people.get, people.list, moments.insert, moments.remove and moments.list. This is a much larger quota to encourage people to use these methods.
The other, more broad, bucket is for all other methods, including those for Activities and Comments and a few others for People.

Create Google Plus Events via API

Is there a possibility to create events for Google Plus Communities via an API?
The only related post I could find is this one: Is there an API for the Google Plus Events but it only considers requesting events.
No, the G+ API is currently read-only.
Note: The Google+ API currently provides read-only access to public data. All API calls require either an OAuth 2.0 token or an API key.

Adwords API developer Token

Can I use Adwords API developer token for multiple applications? In more detail, say if I have a website where I am using adwords API developer token, Can I use the same token for another application. Ofcourse both applications accessing the same account after all.
Thanks,
Murali.
You can use the AdWords API across different applications with just one API token, just make sure though that you are caching the authentication response and re-using those tokens otherwise you'll hit the throttle limit. (Incidentally, logging in is possibly the slowest part of their API, so caching the response will speed up your application considerably)
No doubt you can use same development token for your multiple applications which are accessing same account. If your applications will access different account then it needs to get different developer token.
For the reference, you can read http://goo.gl/zLBPF
Hope it will help you.
Murali,
You need just one developer token, whether your application(s) access same account or different accounts (whether linked under the same MCC hierarchy or not). As a matter of fact, AdWords API Terms and Conditions explicitly prohibits you from getting more than one developer token.
If you use a developer token to make calls, you will be charged for API cost to the account holding the developer token. This is another reason why you should treat your developer token as a password and should reset it immediately if you expose it to the public by say, posting it publicly on a forum.
I also wish to point out that the official AdWords API forum is http://groups.google.com/group/adwords-api, you can ask your questions there and someone will answer your questions in a day or two.

Yes, Adwords even has channels that you can create to separate your ad campaigns
