1msg — messaging automation via API

integrations

1msg is a Claude Code skill that connects an AI agent to the 1msg unified messaging platform via the Membrane CLI, enabling automated communication management across messaging channels. It provides 16 built-in actions covering sending messages, files, templates, reactions, locations, and contacts, as well as uploading media, retrieving channel statistics, managing profile settings, and configuring webhooks. Membrane handles authentication and credential refresh automatically — a one-time browser or headless login is all that's needed. For cases not covered by built-in actions, the skill supports direct proxied requests to the 1msg API with authentication headers injected transparently. It's a practical choice for businesses and developers looking to automate messaging workflows or integrate multi-channel communication into agent-driven pipelines.
