Hi
Does anyone have information on the correct way to add Gift Aid declarations.
We have been directed to the ‘NXT Data Integration’ api which has a ‘Create a tax declaration’ endpoint.
Currently we can succesfully add the Gift Aid Declaration however we do not know how to update it i.e how do we change the declaration to a ‘No’?
There is a ‘Edit a tax declaration’ Patch. I assume this is what we need. But how how do you check incase there is no previous declaration!
There is no clear documentation on how to do this the correct way. So am reaching out here.?
