Description
Remove the dispatch() method from the PHP client library.
The dispatch() method was initially introduced during early iterations of the Metrics Platform that used the monoschema. Now that we've pivoted to using the data contract model, this and related methods should be removed in favor the the api submit methods.
This task is dependent on making sure no instruments are currently using monoschema to send events.
Acceptance Criteria
- The dispatch() and supporting methods are removed from the PHP client.
- Update relevant tests.
- Documentation is updated accordingly.
