I am experimenting with creating a link between Zapier and Freeagent. My end goal is to be able to automatically create a new invoice using details included in a purchase order PDF sent to a specific mailbox. In theory it’s all doable.
So far, I’ve got the API connected to Zapier and have got it to Poll details from FA. However, when I try to POST something back to FA (a new contact as a test) I get an authentication error.
Are there any examples of how a simple action should be set up in Zapier that anyone would be willing to share with me?
