What is connectapi?

connectapi is becoming the scripted administration surface for Posit Connect.

connectapi is the R client for the Posit Connect server API, covering content deployment, scheduling, usage data and permissions. Recent releases concentrate on OAuth integrations, which went from unmanaged to full CRUD in 0.9.0 and reached Connect Cloud in 0.12.0. Interleaved with that is steady removal of functions deprecated several versions back.

What is Resend?

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

connectapi is becoming the scripted administration surface for Posit Connect.

◆ Current state

connectapi is the R client for the Posit Connect server API, covering content deployment, scheduling, usage data and permissions. Recent releases concentrate on OAuth integrations, which went from unmanaged to full CRUD in 0.9.0 and reached Connect Cloud in 0.12.0. Interleaved with that is steady removal of functions deprecated several versions back.

◆ Where it's heading

Two directions run in parallel. The package is widening from a deployment client into an administration surface, through integrations, content search and content locking, which lets Connect configuration live in code rather than in the admin UI. At the same time it prunes aggressively: image helpers deprecated since 0.3.1 and job functions deprecated since 0.6.0 were both removed in this window, with set_schedule_*()'s activate argument on the same path. The result is a smaller but more capable API.

◆ Prediction

The deprecation cycle is announced in advance, so the activate argument is the next likely removal. On the feature side, Connect Cloud support has so far landed only for OAuth and looks unfinished.

Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.

◆ Current state

Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.

◆ Where it's heading

Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.

◆ Prediction

Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
