For Agents

Drive Expensify export, reconciliation, employee update, and download operations through a single integration-server endpoint by varying the request payload.

Connect the Expensify Integration Server API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Expensify Integration Server 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.

Install Jentic One Beta (Self-Hosted)

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

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.

View OpenAPI Document

Jentic publishes the only available OpenAPI document for Expensify Integration Server API, keeping it validated and agent-ready.

Jentic publishes the only available OpenAPI specification for Expensify Integration Server API, keeping it validated and agent-ready. The Expensify Integration Server exposes a single endpoint that accepts a JSON request describing the operation to perform — exporting reports, reconciling reports, updating employees, or downloading exported files — with credentials and command parameters bundled inside the request body. Although the surface is one POST, the request payload selects from the Export, Reconciliation, Employee Updater, and Download command families documented by Expensify, making it the canonical hook for finance-tool integrations and accounting exports.

Use Cases

Patterns agents use Expensify Integration Server API API for, with concrete tasks.

★ Monthly Report Export to Accounting

Schedule a job that POSTs an Export command to /Integration-Server/ExpensifyIntegrations every month, pulling all approved reports for the period in a configured template and forwarding them into the general ledger. This automates the manual export step that finance teams typically run from the Expensify dashboard.

POST /Integration-Server/ExpensifyIntegrations with an Export command for last month's approved reports and write the resulting file into the accounting integration.

Bulk Employee Updater

When HR rolls out a new policy, push an Employee Updater command through the integration server to update Expensify employee records with the new approver, policy, or department in one call. The single-endpoint design keeps the integration small while still handling bulk changes.

POST an Employee Updater command with a list of employees and their new policy or approver assignments.

Reconciliation Run for Closing the Books

Run a Reconciliation command at month-end that compares Expensify reports against ledger entries and produces a reconciled file. This shortens the close cycle by replacing manual cross-checks with a single automated request.

POST a Reconciliation command for the month's date range and ingest the reconciled file into the close workpapers.

AI Agent Finance Operator via Jentic

An AI agent given access to the Expensify Integration Server through Jentic can dispatch the four command families by intent without crafting raw JSON envelopes. Jentic stores the partner credentials and binds them to the request body, so the agent only specifies the action and parameters.

Through Jentic, call expensify_export_reports with the desired template and date range to retrieve last month's approved reports.

DESCRIPTION

POST

/Integration-Server/ExpensifyIntegrations

/Integration-Server/ExpensifyIntegrations

Single integration-server endpoint dispatching Export, Reconciliation, Employee Updater, and Download commands

Why though Jentic?

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

Credential isolation

Expensify partner credentials are stored encrypted in the Jentic vault and merged into the integration-server request body at execution time, so the agent never builds the credential envelope by hand.

Intent-based discovery

Agents search Jentic by intent (for example 'export Expensify reports' or 'reconcile Expensify reports') and Jentic returns the integration-server operation pre-shaped for the requested command family.

Time to first call

Direct integration: 1-2 days to model the four command families and partner-credential body shape. Through Jentic: under 30 minutes — search, load, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Alternative

Ramp API

Ramp offers card and expense management with native API endpoints rather than a single command bus.

Choose Ramp when corporate cards and built-in expense workflows matter more than direct Expensify report templates.

Alternative

Brex API

Brex provides corporate cards and expense management with a granular REST API.

Choose Brex when the company already runs Brex cards and prefers REST resources to a single integration-server endpoint.

Complementary

HubSpot CRM Companies API

HubSpot CRM holds the company records that often correspond to Expensify policies.

Pair with Expensify when companies tracked in CRM also need expense-policy provisioning.

FAQs

Specific to using Expensify Integration Server API API through Jentic.

Why is there no official OpenAPI spec for the Expensify Integration Server API?

Expensify documents the integration server as a JSON-payload contract rather than an OpenAPI spec. Jentic generates and maintains this spec so that AI agents and developers can call Expensify Integration Server 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 Expensify Integration Server API use?

The spec does not declare a top-level securityScheme on /Integration-Server/ExpensifyIntegrations because Expensify expects partner credentials inside the request body alongside the command. Through Jentic, those partner credentials are stored in the encrypted Jentic vault and merged into the body at execution time.

Can I export Expensify reports with this API?

Yes. POSTing an Export command to /Integration-Server/ExpensifyIntegrations runs an export against approved reports using a chosen template, returning either the file directly or a handle to fetch it via the Download command.

What are the rate limits for the Expensify Integration Server API?

The OpenAPI specification does not encode explicit rate limits. Exports and reconciliation runs are typically large, infrequent operations, so schedule them rather than polling, and back off on 5xx responses while the integration server processes the job.

How do I run a monthly export through Jentic?

Install with pip install jentic, then have the agent issue the search-load-execute flow with the query 'export Expensify reports for the month'. Jentic returns the operation backed by /Integration-Server/ExpensifyIntegrations with the Export command pre-shaped; the agent supplies the date range and template.

Can I update employees in bulk?

Yes. The Employee Updater command, sent as a payload to /Integration-Server/ExpensifyIntegrations, takes a list of employees plus their policy or approver changes and applies them in one request.
