Hello community,
I’m in search of a Gmail add-on that can load a Salesforce page on the right-hand side of my Gmail interface. When I tried to implement this using Apps Script, an error appeared stating that permission was needed to fetch the URL. Has anyone successfully developed a solution like this or can offer some advice? Your suggestions or shared experiences would be extremely valuable. Many thanks in advance for any assistance you can provide.
Based on my experience with similar integrations, success typically revolves around ensuring that all authorization scopes are correctly declared in the add-on manifest. I encountered permission issues initially when trying to embed an external page. Meticulous configuration of OAuth settings and aligning with Google’s Content Security Policy was crucial. Careful testing in a controlled environment helped me iron out the challenges. I recommend reviewing Salesforce’s API limits and proper URL whitelisting to prevent such permission errors from recurring. This method ultimately provided a smooth and secure integration.
