`POST /found_documents`	Uploads a newly discovered document, such as an order form or a quote, for review.
`POST /orders`	Uploads an order document.
`POST /activity_records`	Uploads activity records, which update the last login or last activity of accounts.
`GET /activity_records/job/{job_id}`	Returns the state of the job that processes uploaded activity records.
`POST /webhooks/airbase/purchase_request_approved/{domain_app_uuid}`	Receives Airbase events as a purchase request’s workflow moves through milestones.
