Senders

Every operation in this group: what it accepts, what it returns and the errors it can answer with.

Operations

What is known about the organisation behind a sender: the line the reading pane shows under an unfamiliar sender, kept per domain for the whole workspace.

GET/senders/{email}

Read what is known about a sender

Scopesthreads:readReads

A sentence or two about the organisation behind the domain of the address, once it has been looked up. A domain nobody has looked up yet is a 404: POST /senders/{email}/research looks it up.

Requires the threads:read scope.

Path parameters

emailstringRequired

An address of the sender, such as [email protected]. Only its domain is read.

Returns

What is known about the sender.

POST/senders/{email}/research

Look a sender up

Scopesthreads:readReads

Searches the web for the organisation behind the domain of the address and keeps what it found for the whole workspace, as the reading pane does the first time it shows a sender. A domain that was looked up before is answered from what was kept, and nothing is searched again. Only the owner of the workspace may look senders up, with a key or an app that is not limited to particular addresses or domains, and a workspace looks up at most 200 a day.

Requires the threads:read scope.

Path parameters

emailstringRequired

An address of the sender, such as [email protected]. Only its domain is read.

Returns

What was found.

Errors

404

Nothing could be found about the domain.

409

ai_not_configured: looking senders up is not available on this server.

429

research_limit_reached: the workspace has looked up 200 senders today.
