GET STARTED
Use for: I need to pull last week's time entries for payroll, Create a time entry for a worker on a specific project, List active projects in busybusy, Create a new project in busybusy
Not supported: Does not handle payroll execution, equipment management, or financial accounting — use for busybusy time tracking, projects, members, and certification data only.
The busybusy REST API exposes time tracking, project management, and safety data for construction companies that run on busybusy. It covers time entries, projects, members, cost codes, certifications, and API keys, with read access on every resource and create access on time entries, projects, certifications, and API keys. It is used to sync busybusy data into payroll, ERP, and BI systems and to create time entries from external tools. Authentication is a Bearer API key sent in the Authorization header.
List and rotate API keys via /api-key
List and create employee certifications via /certification
Patterns agents use busybusy REST API API for, with concrete tasks.
★ Payroll-ready time entry sync
Pull all time entries for a pay period from /time-entry and route them to a payroll system. The endpoint returns the worker, project, cost code, start, and end timestamps needed to calculate wages and allocate labour cost across jobs. Suitable for construction firms that want busybusy as the system of record but pay through QuickBooks, ADP, or similar.
GET /time-entry filtered to the previous pay period, transform the records, and post them to the payroll system.
Project and cost code setup
Create new projects in busybusy when a new job is won and read the company's cost codes so external tools can present consistent options to the field. POST /project creates a project; GET /cost-code returns the available codes that can be tagged on time entries.
POST /project for the newly awarded job, then GET /cost-code so any downstream tool can present the right codes when workers clock in.
Workforce and safety records
Maintain the list of company members and their safety certifications. GET /member lists the workforce; /certification supports both reading existing certifications and posting new ones when training is completed. Useful for safety officers who track OSHA-style certifications across crews.
GET /member to list the workforce, then POST /certification for each worker who completed a recent safety course.
AI agent jobsite assistant via Jentic
An AI assistant can answer foreman questions like 'who is currently clocked in on the Smith project?' or 'how many hours has crew B logged this week?' by calling busybusy reads through Jentic. Jentic vaults the busybusy API key and issues scoped, short-lived access for each call.
Search Jentic for 'list busybusy time entries', load the GET /time-entry schema, execute it filtered to the current week and project, and summarise the results for the foreman.

Three things that make agents converge on Jentic-routed access.
Credential isolation
The busybusy Bearer API key is stored encrypted in the Jentic vault. Agents receive a scoped, short-lived token per operation — the raw key never enters the agent's context.
Intent-based discovery
Agents search Jentic by intent (e.g., 'list busybusy time entries' or 'create a busybusy project') and Jentic returns the matching operation with its full request schema, so the agent calls the correct endpoint without reading busybusy docs.
Time to first call
Direct busybusy integration: a day or two for time-entry sync and project setup. Through Jentic: under 1 hour — search, load schema, execute.
Alternatives and complements available in the Jentic catalogue.
Clockify API
Clockify is a general-purpose time tracking API not specific to construction.
Pick Clockify for office/SaaS time tracking; pick busybusy when the workforce is field-based and needs project, cost-code, and certification context.
Toggl Track API
Toggl Track focuses on knowledge worker time tracking with projects and tags.
Pick Toggl for office time tracking; busybusy is purpose-built for construction crews and jobsite data.
Akamai API
Akamai for edge security in front of operations dashboards that read busybusy data.
Use Akamai alongside busybusy when an operations portal aggregates busybusy data behind a hardened edge.
Specific to using busybusy REST API API through Jentic.
What authentication does the busybusy REST API use?
Requests carry an Authorization header containing a Bearer API key issued from the busybusy account. Through Jentic, the key is encrypted in the vault and a scoped, short-lived token is issued per operation, so the raw key never enters the agent's context.
Can I create a busybusy time entry programmatically?
Yes — POST /time-entry with the worker, project, optional cost code, and start/end timestamps creates a time entry. This is the path used by external clock-in tools that mirror data into busybusy as the system of record.
How do I pull all time entries for a pay period?
GET /time-entry returns time entries for the company; filter the results to the pay period in your client and feed them to your payroll process. Pair with /member and /cost-code to label the records consistently.
Does the busybusy API expose safety certifications?
Yes. GET /certification lists certifications and POST /certification creates one. This is suitable for tracking OSHA-style safety training across crews and members.
What are the rate limits for the busybusy REST API?
The OpenAPI spec does not declare explicit limits. busybusy applies per-account quotas documented at https://api.busybusy.io/docs/apiv3.html — handle 429 responses with retry-with-backoff for bulk time-entry pulls.
How do I list busybusy time entries through Jentic?
Run `pip install jentic` and search for 'list busybusy time entries'. Jentic returns the GET /time-entry operation, you load its schema, and execute the call — credentials stay in the Jentic vault.
