オペレーション
The address book, and it belongs to the workspace rather than to whoever saved a row. Every member and every key on the workspace reads and writes the same book.
A contact is addressed by its email address on every route here, because no id is exposed. Two things write rows: somebody saving one, in the app or through this API, which lands as manual, and a member sending mail from the app composer, which lands as auto. Mail ARRIVING from an address creates nothing, so an empty book on a busy mailbox is the expected state rather than a fault.
GET/contacts
List contacts
The address book belongs to the workspace, so every key on it reads the same rows and a contact saved by one member is visible to the rest.
Most recently seen first, with contacts that have never been mailed last. source is manual for an address somebody saved, in the app or through this API, and auto for one recorded because a member sent mail to it from the composer. Mail arriving from an address creates no contact.
Paging is keyset. Pass nextCursor back as cursor while hasMore is true.
Requires the contacts:read scope.

POST/contacts
Create a contact
The address is the identity, so there is no id to choose and no id in the response. It is trimmed and lower cased before it is stored, and the contact is saved with source set to manual.
The new contact joins the built-in default audience as it is written, and any audience named in audienceIds alongside it. Naming audiences also requires the audiences:write scope.
An address already in the book is refused rather than merged, so a retry cannot overwrite a name somebody edited in the app.

GET/contacts/people
List people
Everyone on the Contacts page in the app: the saved contacts, and every address seen in mail as the sender or a recipient of a thread's newest message, with the number of threads and when mail last moved. A person seen in mail and saved is one row.
The addresses seen in mail are listed only when the key also holds threads:read, because they are read out of the mail. Without it the rows are the saved contacts alone and seen is false. A key limited to particular addresses or domains gets the saved contacts alone too, with seen false, even when it holds threads:read, because the other addresses would be read out of the mail of every address in the workspace. Deleted addresses and the mailbox's own addresses are left out.
blockedBy names the workspace blocklist rule that blocks a row, the same rule blocked=true filters on.

POST/contacts/batch-delete
Delete contacts in bulk
Deletes up to 200 addresses in one call, each the way DELETE /contacts/{email} deletes one: a saved contact goes with its notes, photo and audience memberships, and every address is hidden, so a send does not record it again. Addresses that were only seen in mail are hidden too. An entry that is not an address comes back in invalid and the rest still go through.

Saves the address the way Add to contacts and Keep in contacts do in the app. An address that is not a contact yet becomes one, answered with 201.

DELETE/contacts/{email}
Delete a contact
Deletes somebody from the contacts the way Delete does in the app. A saved contact goes with its notes, its photo and every audience membership, the built-in default one included. The address is then hidden: it leaves GET /contacts/people, and mail sent to it from the app composer no longer records it. The address can be one that was only ever seen in mail.
No mail moves. Saving the address again, with POST /contacts or PUT /contacts/{email}, brings it back as a new contact.

Block a contact
Puts the address on the workspace blocklist, the one PATCH /settings edits as blockedSenders, so mail from it is refused from then on. A plus tag is dropped: blocking [email protected] blocks [email protected]. When a rule already blocks the address, a whole-domain one included, nothing is added and created is false.

PUT/contacts/{email}/audiences
Set a contact's audiences
Sets exactly which audiences the contact is in, the way the audience picker on a contact does in the app. The contact joins every listed audience it is not in yet and leaves every other one, in one transaction. The built-in default audience is always kept, so { "audienceIds": [] } leaves the contact in the default audience alone. Memberships it keeps also keep their addedAt.
The address is matched case insensitively and has to be a contact already. Create it with POST /contacts, which takes audienceIds too. An id that names no audience in this workspace refuses the whole call and changes nothing.
audiences:write is the only scope checked, because this writes memberships rather than the contact. Sending the same list again changes nothing, so a retry is safe.
