Dialpad Intergration

Dialpad Intergration

Hi All, 

Previously I have had Dialpad intergration working correctly, records would transfer etc. 

I have come back from break and now Zoho and Dialpad are not playing nicely together. 

Whenever I try to re-authorise Dialpad to talk to Zoho CRM I get the following error

Error getting zoho access token. Status Code: 400

Any one have any idea on solutions?

Thanks 

Kevin
