I attempted to create an access token for setting up the conversion API in Events Manager. However, the agency's two-factor authentication generator wasn't functioning, preventing me from obtaining the access token.
As a workaround, I used the Access Token Tool in the Graph API and clicked on "extend Access Token" to generate a new access token. Fortunately, the conversion API started working, but I'm curious about the difference between these two methods.
I found the difference between the two methods. The "extend Access Token" option in the Graph API tool has an expiration, while the other one has no expiration.
