Install Jentic One Beta

Connect the Sync for Expenses API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Sync for Expenses 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 Sync for Expenses API.

For Agents

Push expense transactions from a card or spend management platform into a customer's accounting software with correct account, tax, and category mapping.

Use for: I want to push a card expense into a customer's QuickBooks ledger, Get the mapping options available for an accounting connection, Check whether the latest sync of expenses succeeded, List the status of every transaction in a given sync run

Not supported: Does not handle commerce sales sync, accounting ledger reads, or payment processing - use for posting expense transactions from a partner platform into accounting software with correct GL mapping only.

Codat's Sync for Expenses API lets corporate card and spend management platforms write expense transactions into a customer's accounting software with the right account mapping, tax rate, and tracking category applied. It manages partner-expense connections, mapping options, sync triggers, and per-transaction status so the platform can show finance teams exactly which expenses reached the ledger and which need attention. It is used by card issuers, expense apps, and travel-and-expense platforms that want one accounting integration covering QuickBooks, Xero, and Sage.

Use Cases

Patterns agents use Sync for Expenses API for, with concrete tasks.

★ Corporate Card Expense Sync

Card issuers and corporate card platforms use Sync for Expenses to write each cardholder transaction into the customer's accounting ledger automatically. The /companies/{companyId}/sync/expenses/syncs endpoint triggers a run and the /sync/expenses/syncs/{syncId}/status endpoint exposes per-transaction status so the finance team sees what posted and what needs review.

Trigger a sync for company {companyId}, then retrieve the latest sync status and list any transactions that failed to post.

Travel and Expense Platform Reconciliation

Travel-and-expense apps use Sync for Expenses to write approved expense reports into accounting platforms with correct GL coding. The /sync/expenses/mappingOptions endpoint surfaces the chart of accounts and tax rates available in the destination, letting the platform offer accurate dropdowns at submission time so each expense lands in the right account when synced.

Fetch mapping options for company {companyId} and return the available GL accounts and tax rates for use in the expense submission UI.

Spend Management Reliability Monitoring

Spend management ops teams monitor sync reliability through the status endpoints. /sync/expenses/syncs/list/status and /sync/expenses/syncs/lastSuccessful/status surface health across customers so the team can investigate failed syncs before the customer's finance team notices the missing entries.

List the status of the last 50 syncs for company {companyId} and report any with status other than 'Success'.

AI Agent Expense Reconciliation

AI agents that handle expense reconciliation use Sync for Expenses through Jentic to remediate failed posts. The agent searches Jentic for 'expense sync status', loads the operation, identifies failed transactions, and triggers a re-sync after correcting the mapping. Jentic isolates the Codat API key in its vault.

Search Jentic for 'sync for expenses status', load the operation, and identify expenses for company {companyId} that failed in the last run.

Why Jentic?

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

Credential isolation

Your Codat API key is stored once, encrypted, by your own Jentic One instance and injected at execution time as the Basic Authorization header. It never enters the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'sync expenses to accounting software' or 'check the last successful expense sync', and Jentic returns the matching Sync for Expenses operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using Sync for Expenses API through Jentic.

What authentication does the Sync for Expenses API use?

The API uses an API key passed in the Authorization header as 'Basic <base64-encoded-key>'. The single security scheme in the spec is named auth_header. Through Jentic, the Codat API key is stored encrypted in the vault and the Authorization header is constructed at execution time.

Can I push corporate card transactions into QuickBooks with this API?

Yes. After creating a partner-expense connection via /companies/{companyId}/sync/expenses/connections/partnerExpense, push expenses through the sync endpoints under /companies/{companyId}/sync/expenses. The transactions arrive in QuickBooks with the GL account, tax rate, and tracking category applied based on the mapping options you supply.

What are the rate limits for the Sync for Expenses API?

Codat does not publish a fixed rate limit in the OpenAPI spec; limits are governed at the company and connection level and depend on the destination accounting platform's own limits. Codat returns HTTP 429 with a Retry-After header when limits are hit and recommends exponential backoff.

How do I check why an expense transaction failed to post through Jentic?

Search Jentic for 'expense sync transaction status', load the GET /companies/{companyId}/sync/expenses/syncs/{syncId}/status operation, and execute it with the sync ID. Install with pip install jentic and use the standard async search, load, and execute flow.

Which accounting platforms does Sync for Expenses support?

Sync for Expenses supports QuickBooks Online, Xero, and Sage as primary destinations using the same endpoint surface. The destination is selected when the partner-expense connection is created, and the mapping options endpoint returns the destination-specific chart of accounts.

Note that the API spec marks this API version as 'prealpha' - is it production-ready?

The OpenAPI spec exposes version 'prealpha' in info.version, indicating Codat may still iterate on the surface. Production deployments should pin to the spec version they tested against and watch for breaking changes; through Jentic the loaded schema is versioned with the spec used at search time.
