I’m using FreeAgent and building Apps for a client who we work for.
My intention is to use Make.com to create invoices from our client’s CRM (BIGIN) using Make.
I’ve signed up for a FreeAgent sandbox account completing all the setup stages as directed within this article.
I’ve now got my OAuth credentials having created a new app. In Make, I’ve added a new FreeAgent module (create contact) and tried making a connection. The Make Login dialog has then asked for my login details which I’ve then entered (using those from the sandbox account above).
This throws an error saying ‘The email and password you entered were incorrect’.
When initiating authorising the app in Google OAuth playground, I don’t get an error about username and password, but I do get an error stating the redirect URI is invalid for this app.
We’ve taken a look at this, and we think it might be that you haven’t registered the redirect_uri that you’re using to compose the authorisation request. You can register the redirect_uri in the developer dashboard, as indicated in our documentation, by going to the developer dashboard > My Apps > Edit App
I hope that helps, but please let us know if you’re still experiencing issues.
