Endorsal automates the collection and display of customer testimonials and reviews, enhancing social proof for businesses.
Endorsal automates the collection and display of customer testimonials and reviews, enhancing social proof for businesses. On Nagent, Endorsal is exposed as a fully-configurable reviews integration that any agent can call — 26 actions, and API key authentication. No code is required to wire Endorsal into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Endorsal to automate the kinds of tasks reviews 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 Endorsal 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 Endorsal, with input parameters and output schema. Drop these into any step of an agent built in Helix.

No publicly available marketplace agent is found using this tool yet. There are 76 agents privately built on Nagent that already use Endorsal.
Build on Nagent
Connect Endorsal 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 Endorsal, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Endorsal is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Endorsal is connected, you configure its 26 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Endorsal 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 Endorsal event fires, the agent kicks off automatically.
Every Endorsal 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 Endorsal ships with 26 pre-built reviews actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Endorsal together with other connected tools.
