Get track information from Spotify API using ISRC code - spotify

Is it possible to get the track id (or better, the entire track metadata) using an ISRC code?

Yes, you can get information about a track given the ISRC using the Search endpoint.
For example, Metallica's Sad But True has the ISRC USEE10001993. A request to the Web API to retrieve the track metadata would be:
https://api.spotify.com/v1/search?type=track&q=isrc:USEE10001993

Instagram feeds using tag name of particular user

I am trying to fetch the instagram feeds to my site using tag name.
https://api.instagram.com/v1/tags/{tag-name}?access_token=ACCESS-TOKEN
above is the api which I am using to get the feeds.
Now the feeds are displaying from all the users who use the tag. I need to restrict the feeds for the particular user who use the tag name.
Anyone come across this?
Thanks,
The current version of the Instagram Api does not have an endpoint that will allow you to get media by tag-name AND user-id. Your best bet is to use 1 of the following endpoints, and then loop through the results and filter out the media that matches the 2nd condition.
Search for posts by given hashtag's name using GET /tags/{tag-name}/media/recent API endpoint request and then filter the response list of media to match the user-id for the particular user in question.
or
Search for posts by the particular user using GET /users/{user-id}/media/recent API endpoint request and then manually check every post if its tags array contains the specific hashtag you are looking for.
I recommend you go with option 2 as that will be faster, since an individual user feed is a much smaller data set than media from 1000s of Instagram users tagged with a hashtag.

Is there a way to get Instagram #Mention History via API or otherwise?

The native application doesn't show all the activity, only the most recent.
Therefore I lose 70-90% of my notifications overnight. There must be a way to get all that historical data.
I told you can't, but, thinking.. you can. :)
The API don't provide that facility.. You can check all endpoints here: http://instagram.com/developer/endpoints/
But you can iterate over all your medias an get all comments and likes. If you store it locally, after, will be possible to request API again and check your new unseen interactions.
It will work for likes and comments.

Do I require authorization from Spotify for isrc code?

I want to make a request to Spotify Web API, getting the isrc code based on song title and artist title.
Do I require authorization for this type of request?
No, you don't need to authenticate your request, though it's advisable if you are going to make lots of requests.
You would use the Search endpoint for finding tracks with a given title and artist name, and then you would get the data for the track using the Get a track endpoint.
There you can find the isrc code in the external_ids field.

How to grab instagram users based on a hashtag?

is there a way to grab instagram users based on a specific hashtag ?
I run contests based on re posting photos with specified hashtag then randomly pick a winner, i need a tool that can grab the usernames of those who reposted that photo and used that hashtag.
You can query instagram using the API. There are official clients for both python and ruby.
You didn't specify what language/platform you are using, so I'll give you the generic approach.
Query instagram using the Tag Recent Media endpoint.
In the response, you will receive a user object that has the user's username, id, profile url, and so on. This should be enough to do what you are describing.
As far as tools, there aren't great options to probably do things exactly how you want. If you just want a simple contest, you could use statigram, but it's not free.
If you roll your own solution, I highly recommend you also do the following:
Implement a rate limiting mechanism such as a task queue so you don't exceed your API calls (5000 per hour for most calls). Also useful for failures/network hicups, etc.
Have users authenticate so you can use OAuth to extend your API calls to 5000/per user/hour to get around #1.
Try the subscribe API if there won't be many items. You can subscribe to a specific tag as well, and you will get a change notification. At that point though you need to retrieve the actual media item(s), and this can cost a lot of API calls depending on how frequent and what volume these changes occur.
If your users don't have much photos/relatively small/known in advance, you can actually query the user's recent media instead and filter in your own code by hash tag.

how subscribing to instagram realtime api helps me to get user/media details

I have subscribed to instagram realtime api to receive POST updates for hashtag #sudhir
I am able to get updates to my server this way :
{"changed_aspect":"media", "subscription_id":2935881, "object":"tag", "object_id":"sudhir", "time":1362748903}
I don't find any user related or media related info in these updates. I found in SO that we have to hit their (instagram) endpoints explicitly to get photos/user info, inspite of subscribing to endpoints.
If we have to make request explicitly, then what is the use of subscribing to particular endpoint.?
What is the use of this json data ({"changed_aspect":"media","subscription_id":2935881,"object":"tag","object_id":"nofilter","time":1362748903}) we get in request body of our servlet. ?
Can we use this data in any way to get actual data of user/media ?
Any help or suggestions would be appreciated :)
Nothing useful I'm afraid. Once you have that information you know that something has changed on Instagram's end. You are then supposed to fire off the corresponding request. From your example it looks like you want to then do a tag/recent/ request and filter out anything earlier than the "time" variable.
Not the easiest way to do things unfortunately but they seem to have decided that the hard way of doing things is the way to go.
