Block Field Updates and API Calls

[Valerie_Armstro]

Hello,

We are currently using the Web Service API to update lead information.  However, when that information is updated, it is updating other values in different fields that we would rather not have overwritten.  If I decided to block field updates from Web Service API for those fields, will the API call return an error and not update any fields or will it continue to function properly without updating the other fields?

Thank you in advance!

Thank you for clarifying, Josh and Kenny!

Josh is correct, it will not throw an error if the field is blocked from updates.

Field blocking will only prevent Overwrites of existing data.

I do not think the API would return an error, but it might as I've seen the import process denote when a field might be blocked for new data.
