Automatic Xero refresh token update in Azure data factory

Question

I use the Xero connector to extract data from xero API in Azure data factory. I use OAuth 2.0 config. The connection is successful but my refresh token expires every 30 minutes. Is there a way to automate the refresh token update?

I realized that the below mentioned link was useful. But can someone elaborate on how to setup the access tokens? [https://learn.microsoft.com/en-us/answers/questions/112731/xero-azure-data-factory-connector-operates-success]

Answer 1

As we know we need to generate refresh token after every 30 min s as earlier got expired to generate it and store it you need to follow steps like below:

• You get an initial refresh token by requesting the offline_access scope during the user authorization. store this token in key vault manually.
• With first web activity get that refresh toke from key vault.
• Now with the set variable store the refresh token as string.
• Using that refresh token, you can generate the new refresh token with the another web activity and below values from this Refreshing access and refresh tokens

POST 
https://identity.xero.com/connect/token

#header
authorization: "Basic " + base64encode(client_id + ":" + client_secret)
Content-Type: application/x-www-form-urlencoded

#body
grant_type=refresh_token
&refresh_token=xxxxxx

• Now store the new and original refresh token to the key vault and use the new in copy activity.
