Hello everyone
Please be so kind as to read my full message before responding.
Thank you for your consideration.
I am currently setting up application user/security role/Postman examples for one CRM-third party system integration.
Unfortunately, update of emailaddress1 in contact seems to consistently fail.
I have assigned minimal permissions to the security role for the application user for the integration.
For some reason I don't understand, any attempt to update contact via API seems to trigger an error that the prvReadActivity permission is missing because of an entity quoteclose, apparently an activity.

I have never even heard of or used this entity and don't know what it's used for.
I don't understand why updating an email address in contact triggers an read attempt on quoteclose.
I have checked the registered contact plugins and workflows which might get triggered upon update of contact, but I have come up empty.
Any ideas, why an update of emailaddress1 causes an attempt to read quoteclose and how to get rid of it, if possible?
Thanks,
Sa.
