This is a breaking change
Existing integrations may stop working after the removal date. Follow the migration guide before you upgrade.
The sender field on POST /v2/messages is deprecated in favour of from, which also accepts sender IDs and short codes. Requests that use sender now return a Deprecation header.
What to do
Rename sender to from in your requests. SDK 2.2 and later do this for you. The removal date in this template is a placeholder: set your own.
