<<<EOREMARKUP
When an object (like a task) is edited, Phabricator creates a "transaction"
and applies it. This list of transactions on each object is the basis for
essentially all edits and comments in Phabricator. Reviewing the transaction
record allows you to see who edited an object, when, and how their edit changed
things.
One common reason to call this method is that you're implmenting a webhook and
just received a notification that an object has changed. See the Webhooks
documentation for more detailed discussion of this use case.
Constraints
===========
These constraints are supported:
- `phids` //Optional list<phid>.// Find specific transactions by PHID. This
is most likely to be useful if you're responding to a webhook notification
and want to inspect only the related events.
- `authorPHIDs` //Optional list<phid>.// Find transactions with particular
authors.
Transaction Format
==================
Each transaction has custom data describing what the transaction did. The
format varies from transaction to transaction. The easiest way to figure out
exactly what a particular transaction looks like is to make the associated kind
of edit to a test object, then query that object.
Not all transactions have data: by default, transactions have a `null` "type"
and no additional data. This API does not expose raw transaction data because
some of it is internal, oddly named, misspelled, confusing, not useful, or
could create security or policy problems to expose directly.
New transactions are exposed (with correctly spelled, comprehensible types and
useful, reasonable fields) as we become aware of use cases for them.
