Xero Oauth2.0

Xero released their Oauth2.0 authenticated access to their API recently.

I am trying to write some flows to use this.

If I use Postman to generate the access code and then use it in flow, all works fine.

 

However the code needs to be refreshed every 30 minutes.

Running the token refresh call in Postman works fine, however it fails in Flow. "error": "unsupported_grant_type"

 

Post to https://identity.xero.com/connect/token

Header

"Authorization": "Basic Rjd..." - valid (checked) token 

"Content-Type": "application/x-www-form-urlencoded"

 

The body of the http call is :-

{
"grant_type":"refresh_token",
"refresh_token":"0134e4a53c...",
"client_id":"F7B7...",
"client_secret":"GEfl..."
}

 

Can anyone shed any light on this please?

Hi @MartinHutchcpa ,

 

Could you please share a screenshot of the configuration of your flow?

Did you ever get this working? I assume, if you are trying the refresh token, you had made the initial authentication work? Could you share that HTTP flow please?

Hi Luke,

I used Postman to get an initial token. The token is saved in a SharePoint list.

I have a flow that refreshes this token and saves it back to the list, this runs every 15 mins.

My flows then use this token from the SharePoint list to do their thing.

Hope this helps.

First off, thank you for replying to a post from 2020.

If my thinking is correct, the initial auth is performed via postman, and the PA flow retrieves the token saved in a sharepoint list?

 

I will explain my scenario. Google form time entry, which essentially was saved to a google sheet. I could extract the new rows and post to a sharepoint list, for time entry for a client. They have since moved to WorkFlowMax; i'm trying to create a similar process.

 

I would need to auth once per day to WFM via API and then POST add time. I imagine being in the position of auth once, and then refresh once per 24 hours, in order to post new data. 

 

You worked out how to refresh such token via PowerA, referencing the original question? 

 

Please can we keep the conversation going, I don't want to give up on my objective! 

cheers
Luke

Hi Luke,

For Xero, the refresh PA is very simple, not sure about Google api endpoint though.

The Google Sheet aspect is easy, as there is a connector.

I have used PostMan for the first time, and have my access token now. 

So I assume I can now bring that into PowerAutomate and work on the refresh cycle. 

Once that is done, I can look at adding new time entry into work flow max.

 

Any pointers with the refresh flow for the token please?

Hi Luke,

I store my token in a Dynamics 365 table, although I have used Sharepoint in the past.

Awesome! Over on GIT is a Postman environment to import. Has all the workings of getting started with the Worflow max api - (GitHub - XeroAPI/workflowmax-postman-oauth2: A postman collection for use with WorkflowMax's API and...

 

So I can get to speed with interacting with the API via Postman and then bring my learnings into Power Automate.

Please could you post the breakdown of the HTTP flow, where you are refreshing the token.

I can't work out what should be in the Body and the Headers, however much I try I get Invalid_Client or Invalid_Request, where trying to refresh

 

Also, how is this string made up: Do I use the text as is, but replace the id and secret?

"Basic " + base64encode(client_id + ":" + client_secret)
LukePWilkins

Its this Authorization string which is throwing me now! I'm getting back Invalid_Client in PA. Could you give me some pointers please on how you have encoded it? I see at the first screen shot, its an expression with Basic and then I assume your base64encode string for client id and pass - how did you encode it?

LukePWilkins

OK I sorted it!!! Wow... talk about learning.

 

In the HTTP call I formed the body as form-data (reference from the way POSTMAN was forming the refresh request) 

 

grant_type=refresh_token&refresh_Token=REFRESHTOKEN&client_id=CLIENTID&client_secret=CLIENTSECRET

 

No need for Authorization header and the base64encode stringScreenshot 2021-05-17 181252.png

Hi @LukePWilkins (et all)

 

Credit for your persistence here.  I am trying to do exactly the same thing and can't seem to get past "{"error":"invalid_client"}".

 

I have successfully authenticated, refreshed tokens, retrieved invoices, and created invoices using Postman.

 

I have created a single flow with the three variables below and validated that the values are all correct and matching what is in Postman.

 

I have also tried formatting the body in JSON (noting to change content-type) however this returns 'invalid request'.

 

When I format the body exactly how you have set out, or copy/pasting from Postman both result in 'invalid client'.

 

My process to test this scenario is as follows:

  1. Generate new token in Postman
  2. Copy access_token and refresh token to environment variables in Postman
  3. Run authentication in Postman (sign in etc)
  4. Run Refresh token in Postman
  5. Run Get connections to obtain and store client_id in environment variables in Postman
  6. Test retrieve and create Invoices in Postman
  7. Ensure token is not expired
  8. Run my refresh token flow in PowerAutomate

 

Hoping you can shed some light on this for me. Here are some of my questions:

  1. There was one auto-generated KEY-VALUE in Postman called "Host" and it mentions that if this is removed it will likely result in a 400 error. It doesn't look like you have included this. Did this cause you any problems?
  2. Did you have to first create a flow for steps 1-3 in my process above in order to run the Refresh Token flow?

 

Here is the the output of my flow:

Any help would be greatly appreciated.

I have the access token and refresh token saved in a txt file on OneDrive. ClientID and Secret are hardcoded in the variables. RefreshToken, retrieves the refresh token from OneDrive, then its a POST to the API

@LukePWilkins 

 

Thanks for the response!

 

I ended up moving client_id, client_secret, xero-tenant-id, access_token, and refresh_token values to a Davaverse table.

 

I am 99.99999% sure these were all the exact same values that I had initialised as variables in my original flow.

 

Then the only change I made is that I noticed you had an uppercase T in the body for 'refresh_Token'.

 

The flow now works perfectly.  I also added a Do Until status code = 200 so it will retry if it fails for any reason. The flow then updates the dataverse table with the new tokenset (access and refresh) details.

 

My flow now looks like this:

Do you have a typo in Grant_type refresh_tocken???? 

I have my flow scheduled to run every 29 mins and refresh the access token. 

Glad you got it sorted! Two people extra now working with the API via Power Automate

@Nebulas , i'm going to look into storing data in the dataverse, which feels as much better option than onedrive TXT file!!!

The best way to make sure you know what's going on in the News & Announcements, to blogs you follow, or forums and galleries you're interested in is to subscribe! These subscriptions ensure you receive automated messages about the most recent posts and replies. Even better, there are multiple ways you can subscribe to content and boards in the community! (Please note: if you have created an AAD (Azure Active Directory) account you won't be able to receive e-mail notifications.)   Subscribing to a Category  When you're looking at the entire category, select from the Options drop down and choose Subscribe.     You can then choose to Subscribe to all of the boards or select only the boards you want to receive notifications. When you're satisfied with your choices, click Save.     Subscribing to a Topic You can also subscribe to a single topic by clicking Subscribe from the Options drop down menu, while you are viewing the topic or in the General board overview, respectively.     Subscribing to a Label Find the labels at the bottom left of a post.From a particular post with a label, click on the label to filter by that label. This opens a window containing a list of posts with the label you have selected. Click Subscribe.     Note: You can only subscribe to a label at the board level. If you subscribe to a label named 'Copilot' at board #1, it will not automatically subscribe you to an identically named label at board #2. You will have to subscribe twice, once at each board.   Bookmarks Just like you can subscribe to topics and categories, you can also bookmark topics and boards from the same menus! Simply go to the Topic Options drop down menu to bookmark a topic or the Options drop down to bookmark a board. The difference between subscribing and bookmarking is that subscriptions provide you with notifications, whereas bookmarks provide you a static way of easily accessing your favorite boards from the My subscriptions area.   Managing & Viewing Your Subscriptions & Bookmarks To manage your subscriptions, click on your avatar and select My subscriptions from the drop-down menu.     From the Subscriptions & Notifications tab, you can manage your subscriptions, including your e-mail subscription options, your bookmarks, your notification settings, and your email notification format.     You can see a list of all your subscriptions and bookmarks and choose which ones to delete, either individually or in bulk, by checking multiple boxes.     A Note on Following Friends on Mobile Adding someone as a friend or selecting Follow in the mobile view does not allow you to subscribe to their activity feed. You will merely be able to see your friends’ biography, other personal information, or online status, and send messages more quickly by choosing who to send the message to from a list, as opposed to having to search by username.
