Contacts

As the name suggests, contacts are a core part of Coherent — the very reason Coherent exists is so you can have secure conversations with your contacts. On this page, we'll dive into the different contact endpoints you can use to manage contacts programmatically. We'll look at how to query, create, update, and delete contacts.
