For Agents

Log activities, manage companies and contacts, and read staff data in Accelo so agents can automate timekeeping, status updates, and CRM hygiene for professional services firms.

Install Jentic One Beta

Connect the Accelo API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Accelo 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 | sh

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 instance

Jentic 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 Accelo API.

View OpenAPI Document

The Accelo API provides programmatic access to the Accelo professional services automation platform, covering activities, companies, contacts, and staff. Activities (the core unit of work in Accelo, covering meetings, emails, calls, and tasks) can be created, retrieved, updated, and deleted, while company and contact endpoints expose the underlying CRM data. The API uses OAuth 2.0 against a per-tenant subdomain at {deployment}.api.accelo.com. It is used by services firms - agencies, consultancies, IT shops - to integrate time tracking, billing, and CRM with their other tools.

Use Cases

Patterns agents use Accelo API for, with concrete tasks.

★ Auto-Logging Client Meetings from a Calendar

A calendar integration listens for meetings tagged as billable and posts them as Accelo activities via POST /api/v0/activities. Each activity records subject, time, and the linked company or contact. Consultants stop manually copying meeting time into Accelo at week's end and billing accuracy improves.

Create an Accelo activity for a 45-minute client meeting linked to the client's company id and the consultant's staff id

Email Capture Into Accelo Activities

An email client plugin pushes outbound and inbound emails to Accelo as activities so the firm has a single timeline per client. POST /api/v0/activities creates the activity with the email body and direction, while GET /api/v0/contacts resolves the contact id by email address. Project leads see all client correspondence in Accelo without searching individual mailboxes.

Look up the contact by email address and log an inbound email body as an activity against that contact

Cross-Tool Status Reporting

A weekly status reporting tool pulls activities by company across all clients and aggregates time, owner, and status into a slide deck. It calls GET /api/v0/activities with company filters for each top client. The result is a status dashboard that does not require staff to fill out a separate weekly report.

Aggregate activities for company id 123 over the last 7 days, grouped by staff member, with total time logged

Agent-Driven Activity Logging via Jentic

An AI assistant inside a consultancy Slack workspace posts activities to Accelo whenever a consultant says 'log 30 minutes on Acme review'. The agent searches Jentic for the right operation, looks up the company id, and posts the activity - all without the consultant ever opening Accelo's UI.

Through Jentic, search 'log a new activity in Accelo', resolve the company by name, and create a 30-minute activity

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your Accelo OAuth client credentials and deployment subdomain are stored once, encrypted, by your own Jentic One instance and injected at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'log a new activity in Accelo', and Jentic returns the matching operation with its input schema, with the deployment subdomain template handled at execution time, so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Accelo API through Jentic.

What authentication does the Accelo API use?

OAuth 2.0 with /oauth2/v0/authorize and /oauth2/v0/token endpoints, scoped per Accelo deployment subdomain ({deployment}.api.accelo.com). Through Jentic, the OAuth flow is brokered and tokens are stored encrypted in the vault.

Can I log time and meetings as activities through the Accelo API?

Yes. POST /api/v0/activities creates an activity with subject, time, and link to a company, contact, or job. PUT updates the same fields and DELETE removes the activity. This is the canonical way to record billable and non-billable work in Accelo programmatically.

What are the rate limits for the Accelo API?

The OpenAPI spec does not document explicit rate limits. Accelo applies per-deployment limits described in their developer documentation, and limits are scoped to OAuth tokens. Implement exponential backoff on HTTP 429 responses.

How do I log an activity through Jentic?

Run pip install jentic, then search 'log a new activity in Accelo'. Jentic returns POST /api/v0/activities with the input schema. Load it, supply the company id, time, and subject, and execute. The deployment subdomain and OAuth token are handled by Jentic's execution layer.

Does the Accelo API expose jobs, retainers, and tickets?

The endpoints in this spec focus on activities, companies, contacts, and staff. Jobs, retainers, and tickets are part of the broader Accelo platform and are not present in this OpenAPI surface. For those resources, use the Accelo developer portal and the activity links to jobs.

Is the Accelo API free to use?

API access is included with paid Accelo deployments - there is no separate API charge, but you need an active Accelo subscription. OAuth client registration is done through the Accelo deployment's admin settings.

Can I limit what my agent is allowed to do with the Accelo API?

Yes. Because Jentic One is self-hosted, you set the rules that decide which Accelo operations and OAuth credentials your agent may use. Accelo puts the activity id in the URL path (/api/v0/activities/{activity_id}), so a rule can pin the agent to a single activity and let it only read and update that record. You choose the operations it can call, so deleting an activity or listing companies is excluded unless you explicitly allow it.
