According to developer.yahoo.com/mail/ and IMAP responses:

* OK [CAPABILITY IMAP4rev1 ID MOVE NAMESPACE X-ID-ACLID UIDPLUS LITERAL+ CHILDREN XAPPLEPUSHSERVICE XYMHIGHESTMODSEQ AUTH=PLAIN AUTH=LOGIN AUTH=XOAUTH2 AUTH=XYMCOOKIE AUTH=XYMECOOKIE AUTH=XYMCOOKIEB64 AUTH=XYMPKI] IMAP4rev1 imapgate-1.8.1_01.20166 imap1009.mail.ne1.yahoo.com

Yahoo Mail can be accessed by IMAP using OAuth(2) authentication.

I registered my app on https://developer.yahoo.com/apps/ so I have got Client ID and Client Secret. I didn't find any scopes(API Permissions) related to Mail. Nevertheless I selected all API Permissions which were presented when I registered my app.

I tried to implement both OAuth and OAuth2.

OAuth2: I cannot get the authorization code for scope "mail-r". When I generate URL(https://api.login.yahoo.com/oauth2/request_auth?client_id=CLIENT_ID&redirect_uri=oob&scope=mail-r&response_type=code) and open it in browser, the page with text "Developers: Please request scope from registered scopes and submit again." is displayed. It works for other scopes. For example, I'm able to get the authorization code for "sdct-r"

OAuth: I'm able to get an access token. But when I send it with AUTHENTICATE XOAUTH2 command, I get "NO [AUTHENTICATIONFAILED] (#AUTH007) Bad scope" response.

So questions is what scope(s) should be set to access Yahoo Mail using IMAP and OAuth(2)?

    It seems mail api is available for the premium mail accounts... looking at packagetracker website, when signing up with yahoo, it shows the mail scope during oauth2 process... I couldn't find a way to include that scope either... If you've found out a way to include it, please post the answer here, It'll be a great help...

  • @Aleksey, please mark user3377687 answer as accepted... I've checked it and it works... it definitely adds the mail full permission if you set the scope as ymrf => full access

Update February 27, 2017: This work-around will not work anymore as Yahoo has unfortunately taken down the cck-form.html page referenced below and does not seem to allow new apps to request mail related API access. Hopefully this changes.

Here is how you can create an App on yahoo with full access to emails. (recently yahoo remove this option from their UI) once proper permissions are in place, getting oauth tokens and accessing mail boxes should be straight forward and I am not covering it here.

  1. Visit https://developer.yahoo.com/oauth/guide/cck-form.html and look for "Here is an example form along with sample values you can use in the form" and copy the example html into a local file and save it. A Copy of the html is available below.

  2. Open the file on browser. fill appropriate info (set scope=ymrf for full mail access) and click on "pop window with debug".

  3. Click on allow on the popup window. Sign in is required if you did not already login to yahoo on the browser.

go to https://developer.yahoo.com/apps/ and you should see your app with appropriate permissions.

  • The solution works but is a work around to something Yahoo have removed from their UI. Does anyone know why they removed it? Also, what is the scope for read-only?

  • @user3377687 , you are a life saver. This miraculously added the permissions to the Yahoo APP... Now the only thing remaining is to get the yahoo documentation on how to access the mails and their headers... It seems they didn't include it in Mail Docs

  • @user3377687 , though I have to check it with OAuth2 flow for yahoo once I complete it... then we'll be double sure that this is a working method... coz this submits the app request as per oauth guide... if this didn't work with OAuth2 requests, we might need to use oauth methods to consume this service

    This workaround doesn't work now. When opening popup in debug mode window tries to open developer.yahoo.com/projects/createconsumerkey and fails with status 404. Is there any another workaround?

As of august 2017, the only way to get the Email address is to use the scope called Profiles - Read/Write Public and Private. A very stupid choice of misleading options by Yahoo, since we don't want to "write" anything at all.

As a bonus headache, this will also return a list of all emails associated with the account, not just the main one. And there's no way to accurately identify which is the real one - the primary=true field returned in the list cannot be trusted.

You have to add the "Mail Read-Only" scope when you're creating/configuring the app on https://developer.yahoo.com/apps/.

Unfortunately, when I just tried to do that on a newly created app, the option wasn't available.

You may have to get in touch with Yahoo to have them allow you to request these scopes.

0

you have to add scope=openid while hitting authorization endpoint, then after obtaining the token after hittng token endpoint, hit profile endpoint with the obtained access token, then we get emails under profile json object

In order for you to see the mail checkboxes in the list of potential scopes, Yahoo have to white-list your developer account. I could not find any documentation about this, or instructions for how to ask for it, so I can't back this up with any documentation.

I have found another way to create an app with the Mail API permissions enabled. I noticed if you include an 'api' parameter in the URL you can specify which scopes you want to include regardless of whether they are checked at the bottom. I noticed if you provided 'api=mail' in the URL it defaults to include Mail permissions. So to create a new app with Mail permissions use this URL:

https://developer.yahoo.com/apps/create/?api=mail

    This creates the client ID and secret, but you get a 'oauth_problem=consumer_key_rejected' when trying to obtain a request token.
