Hi
I have created a new app in the Developer Dashboard in order to run a Webhook from our CRM (GenieAI, based on GoHighLevel) to create invoices when my team send a structured SMS to a specific number.
I have the Webhook code created and hosted, but when I get to the point of integration with FreeAgent’s API I’m having difficulties.
I have created the app in the Developer Dashboard and made note of the OAuth identifier and OAuth secret, then attempted to authorise the app.
Every time I attempt to authorise the app, I log in to my account and get the message
“Unknown Application
We don’t recognise this app. Please get in touch with the author of the application you’re trying to approve.”
Please could you advise me how to resolve this?
Many thanks
Hi Dave,
Welcome to our API Forum! And thank you for your post.
I’ve done a bit of testing, and I think the issue you’re facing is that you aren’t passing your OAuth Client ID (also known as the OAuth identifier when viewing your app’s details in the Developer Dashboard) correctly. I tried altering my Client ID and tested trying to authorise my app and I got the same message as you.
I would look into how you’re passing this information to the endpoint and ensure the details passed are also correct.
Please let me know if you need further help on this!
Thanks,
Katie
Hi Katie
Thank you so much for your reply!
I’m still fairly new to development, so wonder if you could advise me how I need to pass this information i.e. the string/link I’d need to add my OAuth identifier into, to get it to work?
Thank you in advance 
Hi Dave,
Unfortunately we can’t give specific advice on how to set up your integrations, but we have a lot of information in our documentation that might help you with getting started.
Best of luck with building your application!
Please do get back in touch if you run into any other issues or have any questions.
Kind regards,
Katie
