I’m using CrewAI Studio to build out my agent. And one of the thing it needs is a HubSpot connection. When I tried to connect via OAuth, it’s erroring out on HubSpot with this message,

“ **Couldn’t complete the connection**

Authorization failed as the redirect URL ‘[https://oauth.crewai.com/oauth/add](https://oauth.crewai.com/oauth/add)’ doesn’t match the app’s registered redirect URL. Please consult the app developer.”

This requires CrewAI to update their app on HubSpot allow [https://oauth.crewai.com/oauth/add](https://oauth.crewai.com/oauth/add). Any CrewAI is listening?

Whitelist that exact redirect URI in the CrewAI HubSpot app

The URL is [https://app.hubspot.com/oauth/23491073/authorize?client\_id=1538b809-d56e-4c30-8b4f-57664475b1d4&redirect\_uri=https%3A%2F%2Foauth.crewai.com%2Foauth%2Fadd&response\_type=code&scope=crm.objects.contacts.write+crm.objects.contacts.read+crm.objects.deals.write+crm.objects.deals.read+crm.objects.companies.write+crm.objects.companies.read&state=[…]&code\_challenge=[…]&code\_challenge\_method=S256](https://app.hubspot.com/oauth/23491073/authorize?client_id=1538b809-d56e-4c30-8b4f-57664475b1d4&redirect_uri=https%3A%2F%2Foauth.crewai.com%2Foauth%2Fadd&response_type=code&scope=crm.objects.contacts.write+crm.objects.contacts.read+crm.objects.deals.write+crm.objects.deals.read+crm.objects.companies.write+crm.objects.companies.read&state=%5B%E2%80%A6%5D&code_challenge=%5B%E2%80%A6%5D&code_challenge_method=S256)

Based on the URL, CrewAI needs to add the redirect\_uri to the allowed redirects in their app on HubSpot.
