Identify why permission errors are occurring in your SharePoint integration with Flowsite and how to resolve them.
This article covers issues where Flowsite is unable to access SharePoint due to insufficient permissions — including admin consent errors and account access restrictions.
What's happening
Flowsite is returning a permission or access denied error when trying to connect to SharePoint or when a flow attempts to upload a file. This may appear during the connection setup or as a failed run in Flowsite.
Why this happens
Your Microsoft tenant requires admin consent before users can grant permissions to third-party apps like Flowsite
The connected Microsoft account does not have sufficient access to the SharePoint site
How to fix it
1. Grant admin consent for the Flowsite app
If your Microsoft tenant has the Do not allow user consent setting enabled, a Microsoft admin must approve Flowsite before any connection can be made. There are three options:
Option A — Admin creates the connection directly: Have a Microsoft admin log in to Flowsite and create the Microsoft connection. This is the simplest option.
Option B — Configure the admin consent workflow: In Microsoft Entra, configure the admin consent workflow to allow users to submit ad-hoc requests for admin approval.
Option C — Request admin consent in advance: Send the following URL to a Microsoft admin. They sign in with their admin account and click Accept. Once accepted, all users in the tenant can connect to Flowsite.
Note: This link does not contain sensitive data and can be shared externally. After accepting, the admin will be redirected to Flowsite — no further action is needed.
2. Verify the connected account has access to the SharePoint site
The Microsoft account used to create the Flowsite connection must have access to the SharePoint site being used in the flow.
Confirm which Microsoft account is currently connected in Flowsite under the Connections tab
Ask your SharePoint admin to verify that account has the necessary access to the relevant site
Once access is confirmed, retry the flow by re-signing the Dashpivot form
If the issue continues
If permission errors persist after following the steps above:
Check whether the Microsoft connection itself has expired or become invalid. See SharePoint Connection Failed in Flowsite for guidance
Consider using a dedicated Microsoft Entra ID account with scoped permissions to manage the Flowsite–SharePoint connection, to reduce the risk of disruption from staff changes
Note that Flowsite uses a User (Delegated) Consent flow — it does not support Admin (App-Only) Consent
