Hi all,
Our team is currently developing an AWS Lamda function that is supposed to automatically insert the names of new customers from one of our databases into our Sage Business Cloud Accounting account. To do so, we have followed this guide to work our way through the authentication process: https://developer.sage.com/api/accounting/guides/authentication/
However, we run into difficulties when being asked to provide a Callback URL for our app. More specifically, we are unsure what URL to provide for the Lamda function.
When we leave it blank or insert localhost for the Callback URL, the following error is produced upon submitting a request to renew an access token: {"$severity":"error","$dataCode":"DataParsingError","$message":"The data you sent could not be processed.","$source":"Proxy"}
Therefore, we are wondering what URL we should provide and whether it is even possible to renew the access token when using a Lamda function. If the latter is the case, are there any workarounds through which we can renew the access token and accomplish what we intend with the Lamda function?
We would appreciate it if you have any thoughts on this.
Best regards,
Christopher Wekel
