Sorry. I transposed POST and PUT. PUT is what it needs to be.
Phil (or anyone else who is listening) - I have a related question. So now that I have an answer to Can asana display data from my application (yes!), I want to know if it can work the other way around. In our application we have a dropdownlist that displays the PA (project administrator). And now when the user changes that in our app, I’m updating it in asana. If the user changes it in asana, is there any way I can know that change it in my app (by updating the database)??? Alternatively, can this field be locked down in asana so that you can only update in my app? That way, the user would only have one entry way into changing the field and it would never get out of sync. We would update it in our app and propagate that to asana one-way only. Thanks!
Sure - you can be notified of Asana changes either by polling for Event information or, preferred, by registering for and receiving webhook notifications when data changes.
No, it’s not possible just to lock down one custom field.
