EchtPost facilitates secure digital communication, encryption, and data privacy, providing a reliable channel for sending confidential documents and messages On Nagent, Echtpost is exposed as a fully-configurable documents integration that any agent can call — 1 action, and API key authentication. No code is required to wire Echtpost into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Echtpost to automate the kinds of tasks documents teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Echtpost into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Echtpost, with input parameters and output schema. Drop these into any step of an agent built in Helix.
ECHTPOST_LIST_TEMPLATESThis tool retrieves a list of all available templates in the Echtpost account. Templates serve as the base design for postcards and are essential for creating cards. The action operates independently using only an authentication token and returns detailed template information including id, name, description, preview URL, type, and creation time. This action is crucial for viewing templates before creating cards and obtaining the necessary template IDs for subsequent actions.

Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
No publicly available marketplace agent is found using this tool yet. There are 36 agents privately built on Nagent that already use Echtpost.
Build on Nagent
Connect Echtpost to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Echtpost, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Echtpost is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Echtpost is connected, you configure its 1 action directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Echtpost steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Echtpost event fires, the agent kicks off automatically.
Every Echtpost action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Echtpost ships with 1 pre-built documents action, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Echtpost together with other connected tools.
