For Agents
Register a Zapier connection for a 1FIT trainer account and post client, prospect, check-in, activity, and workout events into 1FIT through user-scoped webhook URLs.
Use for: I need to register a Zapier connection for a 1FIT trainer account, Verify that a 1FIT Zapier connection is still authenticated, Send a client.created event into 1FIT when a new client signs up elsewhere, Forward a completed workout from a fitness tracker into 1FIT
Not supported: Does not handle payments, scheduling, workout program design, or messaging — use only for delivering Zapier-routed lifecycle, activity, check-in, and workout events into a 1FIT trainer account.
Jentic publishes the only available OpenAPI specification for 1FIT Zapier Webhook API, keeping it validated and agent-ready. The 1FIT Zapier Webhook API connects external automation tools to a personal trainer's 1FIT account, letting third-party systems register a Zapier connection, validate it, and post lifecycle events into 1FIT through a user-scoped webhook URL. It accepts a fixed set of event types covering client and prospect creation, client activation and deletion, check-in submissions, activity logs, and completed workouts. Authentication is a JWT bearer token, and every event uses a shared envelope with an event name, timestamp, and event-specific data block.
Install Jentic One Beta
Connect the 1FIT Zapier Webhook API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the 1FIT Zapier Webhook API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with 1FIT Zapier Webhook API.
Register a Zapier connection for a 1FIT account using key, secret, and endpoint identifiers
Validate that an existing Zapier connection and its credentials are still working
Post a client.created or prospect.created event with name, email, mobile, and check-in cadence into 1FIT
Send activity.logged events with duration, distance, heart rate, and calories from a connected fitness tool
Forward workout.completed events with rated workouts, exercises, and elapsed time into a trainer's 1FIT workspace
Deliver checkin.submitted and client lifecycle events (activated, deleted) to keep 1FIT client records in sync
Use Cases
Patterns agents use 1FIT Zapier Webhook API for, with concrete tasks.
★ Sync new clients from a sales tool into 1FIT
When a personal trainer closes a deal in an external CRM, an automation can post a client.created event to the 1FIT Zapier webhook with first name, last name, email, mobile, and check-in cadence. 1FIT receives the payload via the user-scoped webhook URL returned at connection setup and creates the client record without manual entry. This removes the duplicate data work between sales pipelines and the trainer's coaching platform.
Call POST /api/integrations/webhooks/zapier/{endpoint} with event=client.created and a CreateClientData payload containing first_name, last_name, email, mobile, and checkin_frequency=weekly
Forward fitness tracker activity into 1FIT
When a client completes a session in a third-party fitness app, an automation can send an activity.logged event to 1FIT with the activity name, duration in seconds, distance in meters, average heart rate, and calories. 1FIT uses the user's webhook endpoint to attribute the activity to the right client by email or mobile. This lets trainers review external workout data inside 1FIT alongside their own check-ins.
Call POST /api/integrations/webhooks/zapier/{endpoint} with event=activity.logged and an ActivityLoggedData payload containing email, activity, duration, distance, hr, and calories
Capture check-in submissions from external forms
When a client submits a weekly check-in through an external form tool, an automation can post a checkin.submitted event to 1FIT with the client's contact details and submission timestamp. 1FIT records the check-in against the matching client so the trainer sees it in their normal check-in review flow. This is useful when a coach prefers a form builder for the questionnaire itself but wants the response logged in 1FIT.
Call POST /api/integrations/webhooks/zapier/{endpoint} with event=checkin.submitted and a CheckinSubmittedData payload containing email, requested_at, and submitted_at
AI agent integration via Jentic
An AI assistant for a personal training business can use the 1FIT Zapier Webhook API through Jentic to register a connection on behalf of a trainer and then route client lifecycle events from upstream tools into 1FIT. The agent searches Jentic for an intent like sync a client into 1FIT, loads the schema for receiveZapierWebhook, and posts each event with the correct envelope. The bearer token is stored in the Jentic vault, so the agent never sees the raw JWT.
Search Jentic for sync a client lifecycle event into 1FIT, load the receiveZapierWebhook schema, and execute a POST to /api/integrations/webhooks/zapier/{endpoint} with event=client.activated

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
The 1FIT JWT bearer token is stored encrypted in the Jentic vault and injected only at execution time. Agents call the API by name and never see the raw token, which removes the risk of leaking trainer credentials through logs or prompts.
Intent-based discovery
Agents search Jentic with intents like sync a client into 1FIT or post a workout completed event, and Jentic returns the matching operation (setupZapierConnection, testZapierConnection, or receiveZapierWebhook) with its WebhookEnvelope schema so the agent can build a valid payload without reading docs.
Time to first call
Direct integration with the 1FIT Zapier endpoints: 1-2 days to handle setup, JWT refresh, the seven event payload variants, and retry logic. Through Jentic: under 30 minutes — search, load the schema, execute the call.

FAQs
Specific to using 1FIT Zapier Webhook API through Jentic.
Why is there no official OpenAPI spec for 1FIT Zapier Webhook API?
1FIT does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call 1FIT Zapier Webhook API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the 1FIT Zapier Webhook API use?
The API uses HTTP bearer authentication with a JWT. Every request to /api/integrations/connections/zapier/setup, /api/integrations/connections/zapier/test, and /api/integrations/webhooks/zapier/{endpoint} requires an Authorization: Bearer <jwt> header. When called through Jentic, the JWT is stored in the Jentic vault and injected at execution time so the agent never handles the raw token.
Can I post completed workouts and activities to 1FIT through this API?
Yes. POST /api/integrations/webhooks/zapier/{endpoint} accepts event=workout.completed with a WorkoutCompletedData payload (workout name, rating, started_at, completed_at, duration, exercises) and event=activity.logged with an ActivityLoggedData payload (activity, duration, distance, hr, calories). Both are routed to the trainer who owns the {endpoint} identifier returned at setup.
What event types does the webhook endpoint accept?
The WebhookEnvelope schema enumerates seven event types: activity.logged, checkin.submitted, client.activated, client.created, client.deleted, prospect.created, and workout.completed. Any other event value is rejected with a 400 response.
What are the rate limits for the 1FIT Zapier Webhook API?
The OpenAPI specification does not define explicit rate limits. Treat the webhook endpoint as a per-user ingest channel and batch unrelated events on the client side. If 1FIT introduces limits in the future, retry on 429 responses with exponential backoff.
How do I register a Zapier connection for 1FIT through Jentic?
Run pip install jentic, then search for register a 1FIT zapier connection. Jentic returns the setupZapierConnection operation; load its schema and execute it with a ConnectionSetupRequest containing key_id, secret, and endpoint_id. The 200 response includes the user-scoped endpoint value to use in subsequent webhook calls.
