facebook permanent Page Access Token

Question

I work on a project that has facebook pages as one of its data sources  It imports some data from it periodically with no GUI involved  Then we use a web app to show the data we already have   Not all the information is public  This means I have to get access to the data once and then keep it  However  I don t know the process and I haven t found a good tutorial on that yet  I guess I need an access token  how can I get it from the user  step by step  The user is an admin of a facebook page  will he have to add some FB app of ours to the page   EDIT  Thanks  phwd for the tip  I made a tutorial how to get a permanent page access token  even with offline access no longer existing   EDIT  I just found out it s answered here  Long-lasting FB access-token for server to pull FB page info

As all the earlier answers are old  and due to ever changing policies from facebook other mentioned answers might not work for permanent tokens  After lot of debugging  I am able to get the never expires token using following steps  Graph API Explorer   Open graph api explorer and select the page for which you want to obtain the access token in the right-hand drop-down box  click on the Send button and copy the resulting access token  which will be a short-lived token Copy that token and paste it in access token debugger and press debug button  in the bottom of the page click on extend token link  which will extend your token expiry to two months  Copy that extended token and paste it in the below url with your pageId  and hit in the browser url https   graph facebook com  page id  fields access token amp access token  long lived token  U can check that token in access token debugger tool and verify Expires field   which will show never   Thats it

I made a PHP script to make it easier  Create an app  In the Graph API Explorer select your App and get a user token with manage pages and publish pages permission  Find your page s ID at the bottom of its About page  Fill in the config vars and run the script    lt  php  args        usertoken   gt          appid   gt          appsecret   gt          pageid   gt        echo generate token  args    function generate token  args        r json decode file get contents  https   graph facebook com v2 8 oauth access token grant type fb exchange token amp client id   args  appid    amp client secret   args  appsecret    amp fb exchange token   args  usertoken           get long-lived token      longtoken  r- gt access token       r json decode file get contents  https   graph facebook com v2 8 me access token   longtoken         get user id      userid  r- gt id       r json decode file get contents  https   graph facebook com v2 8   userid  accounts access token   longtoken         get permanent token     foreach  r- gt data as  d  if  d- gt id   args  pageid    return  d- gt access token

Most of the answers above now doesn t give permanent token  they only extend it to 2 months  Here s how I got it   From  Graph Explorer tool 0  select the relevant permissions and get the short lived page access token   Go to debugger tool 1 and paste your access token  Then  click on  Extend Token  button at the bottom of the page  Copy the the extended token and use it in this API  https   graph facebook com v2 10 me fields access token amp access token  lt extended access token gt  This should return you the permanent access token  You can verify it in debugger tool  the expires at field should say  Never

If you are requesting only page data  then you can use a page access token  You will only have to authorize the user once to get the user access token  extend it to two months validity then request the token for the page  This is all explained in Scenario 5  Note  that the acquired page access token is only valid for as long as the user access token is valid

While getting the permanent access token I followed above 5 steps as Donut mentioned  However in the 5th step while generating permanent access token its returning the long lived access token Which is valid for 2 months  not permanent access token which never expires   what I noticed is the current version of Graph API is V2 5  If you trying to get the permanent access token with V2 5 its giving long lived access token Try to make API call with V2 2 if you are not able to change version in the graph api explorer hit the API call https   graph facebook com v2 2  account id  accounts access token  long lived access token  in the new tab with V2 2  then you will get the permanent access token Which never expires

As of April 2020  my previously-permanent page tokens started expiring sometime between 1 and 12 hours  I started using user tokens with the manage pages permission to achieve the previous goal  polling a Page s Events   Those tokens appear to be permanent   I created a python script based on info found in this post  hosted at github com k-funk facebook permanent token  to keep track of what params are required  and which methods of obtaining a permanent token are working

Following the instructions laid out in Facebook s extending page tokens documentation I was able to get a page access token that does not expire   I suggest using the Graph API Explorer for all of these steps except where otherwise stated   0  Create Facebook App  If you already have an app  skip to step 1    Go to My Apps  Click    Add a New App   Setup a website app    You don t need to change its permissions or anything  You just need an app that wont go away before you re done with your access token   1  Get User Short-Lived Access Token   Go to the Graph API Explorer  Select the application you want to get the access token for  in the  Application  drop-down menu  not the  My Apps  menu   Click  Get Token     Get User Access Token   In the pop-up  under the  Extended Permissions  tab  check  manage pages   Click  Get Access Token   Grant access from a Facebook account that has access to manage the target page  Note that if this user loses access the final  never-expiring access token will likely stop working    The token that appears in the  Access Token  field is your short-lived access token   2  Generate Long-Lived Access Token  Following these instructions from the Facebook docs  make a GET request to     https   graph facebook com v2 10 oauth access token grant type fb exchange token amp client id  app id  amp client secret  app secret  amp fb exchange token  short lived token    entering in your app s ID and secret and the short-lived token generated in the previous step   You cannot use the Graph API Explorer  For some reason it gets stuck on this request  I think it s because the response isn t JSON  but a query string  Since it s a GET request  you can just go to the URL in your browser   The response should look like this        access token   ABC123   token type   bearer   expires in  5183791     ABC123  will be your long-lived access token  You can put it into the Access Token Debugger to verify  Under  Expires  it should have something like  2 months    3  Get User ID  Using the long-lived access token  make a GET request to      https   graph facebook com v2 10 me access token  long lived access token    The id field is your account ID  You ll need it for the next step   4  Get Permanent Page Access Token  Make a GET request to     https   graph facebook com v2 10  account id  accounts access token  long lived access token    The JSON response should have a data field under which is an array of items the user has access to  Find the item for the page you want the permanent access token from  The access token field should have your permanent access token  Copy it and test it in the Access Token Debugger  Under  Expires  it should say  Never

Another PHP answer to make lives easier  Updated for Facebook Graph API 2 9   Just fill  er up and load    lt  php  args     -- Permanent access token generator for Facebook Graph API version 2 9 --     Instructions  Fill Input Area below and then run this php file   -- INPUT AREA START --        usertoken   gt          appid   gt          appsecret   gt          pageid   gt      -- INPUT AREA END --      echo  Permanent access token is   lt input type  text  value    generate token  args     gt  lt  input gt    function generate token  args        r json decode file get contents  https   graph facebook com v2 9 oauth access token grant type fb exchange token amp client id   args  appid    amp client secret   args  appsecret    amp fb exchange token   args  usertoken           get long-lived token      longtoken  r- gt access token       r json decode file get contents  https   graph facebook com v2 9 me access token   longtoken         get user id      userid  r- gt id       r json decode file get contents  https   graph facebook com v2 9   userid  fields access token amp access token   longtoken         get permanent token     if  r- gt id   args  pageid     finaltoken  r- gt access token      return  finaltoken      gt    Addendum   alternative   Graph 2 9 onwards   you can skip much of the hassle of getting a long access token by simply clicking Extend Access Token at the bottom of the Access Token Debugger tool  after having debugged a short access token  Armed with information about pageid and longlivedtoken  run the php below to get permanent access token    lt  php  args     -- Permanent access token generator for Facebook Graph API version 2 9 --     Instructions  Fill Input Area below and then run this php file   -- INPUT AREA START --        longlivedtoken   gt          pageid   gt      -- INPUT AREA END --      echo  Permanent access token is   lt input type  text  value    generate token  args     gt  lt  input gt    function generate token  args    r json decode file get contents  https   graph facebook com v2 9   args  pageid    fields access token amp access token   args  longlivedtoken        return  r- gt access token      gt    Although the second code saves you a lot of hassle  I recommend running the first php code unless you are in a lot of hurry because it cross-checks pageid and userid  The second code will not end up working if you choose user token by mistake      Thanks to dw1 and Rob

Application request limit reached   4  - FB API v2 1 and greater  This answer led me to the  ultimate answer for us  and so it is very much related so I am appending it here  While it s related to the above it is different and it seems FB has simplified the process some   Our sharing counts on our site stopped worked when FB rolled over the api to v 2 1  In our case we already had a FB APP and we were NOT using the FB login  So what we needed to do was get a FB APP Token to make the new requests  This is as of Aug  23 2016    Go to  https   developers facebook com tools explorer Select the api version and then use GET and paste the following     oauth access token client id  app-id  amp client secret  app-secret  amp grant type client credentials   You will want to go grab your app id and your app secret from your app page  Main FB Apps developer page Run the graph query and you will see         access token    app-id app-token       token type    bearer      Where  app-id  and  app-token  will be your app id from your FB app page and the generated FB App HASH you just received  Next go test your new APP access token  FB Access Token tester You should see  by pasting the  app-token  into the token tester  a single app based token without an expiration date time    In our case we are using the FB js sdk so we changed our call to be like so  please note this ONLY gets the share count and not the share and comment count combined like it used to be    FB api           GET           this is our FB app token for our FB app          access token  FBAppToken           id     shareUrl    fields   id og object  engagement        This is now working properly  This took a lot of searching and an official bug report with FB to confirm that we have to start making tokenized requests to the FB api   As an aside I did request that they  FB  add a clue to the Error code   4  that mentions the tokenized request   I just got another report from one of our devs that our FB comment count is broken as well due to the new need for tokenized requests so I will update this accordingly
