Error code dictionary - DCS Technical Documentation

📄 Guide

This page is the complete set of error codes for the Corporate Card open API: 11 general codes and 52 business codes. Use it as a quick reference — the trigger conditions and request details for each code live in the guide pages named in the “Returned by” column. Three rules for handling errors:

Branch on the error code, never parse message: message is for humans and its wording will change; the code is the contract.
Never judge success by HTTP status: business failures currently return HTTP 500 across the board. The only reliable test is code == "SYS_SUCCESS".
SYS_ERROR and DAPI_SERVICE_UNAVAILABLE mean the outcome is unknown: for money-moving calls (transfers, card applications) retry with the same idempotency key or reconcile by query — do not treat them as failures outright. If you meet a code not listed here, treat that call as failed; never treat it as success.

Batch endpoints (rule bind / unbind) report errors on two levels: batch-level errors in the top-level code, and per-item failure reasons in data.failTargets[].errorCode, drawn from the same code set. See Binding and unbinding.

General error codes

Independent of any specific endpoint; any call may return them. The body is the standard envelope { code, message, data }.

Response envelope

Code	HTTP	Description
`SYS_SUCCESS`	200	Success
`SYS_ERROR`	500	System error (outcome unknown — retry money-moving calls with the same idempotency key)

Authentication and gateway checks

Code	HTTP	Description
`DAPI_API_KEY_EMPTY`	401	API key missing or invalid
`DAPI_TIMESTAMP_EXPIRED`	401	Timestamp outside the window
`DAPI_NONCE_ILLEGAL`	401	Illegal nonce
`DAPI_NONCE_DUPLICATE`	401	Duplicate nonce
`DAPI_SIGNATURE_ERROR`	401	Signature verification failed
`DAPI_IP_NOT_ALLOWED`	401	IP not on the allowlist
`DAPI_PERMISSION_DENIED`	401	Access denied
`DAPI_PARAM_INVALID`	400	Invalid parameters (including structural gaps such as “none of the five control groups configured”)
`DAPI_SERVICE_UNAVAILABLE`	500	Downstream unavailable (outcome unknown — handle like `SYS_ERROR`)

`CARD_RULE_REQUIRED`	A velocity rule is required for this card profile	Card application
`CARD_RULE_INVALID`	Rule missing, not owned by this company, or not ACTIVE (one code for all three, to prevent probing other companies’ rules)	Card application
`CARD_RULE_DUPLICATE`	The subject is already bound to this rule	Card application, rule binding
`CARD_RULE_CURRENCY_NOT_MATCH`	No overlap between the rule’s currencies and the card’s chargeable currencies	Card application, rule binding

`SUBJECT_INVALID`	Subject missing, not ACTIVE, or not under the given company	Subject checks in the funds and velocity domains (including per-item results of batch calls)
`SUBJECT_TYPE_NOT_ALLOWED`	This slot does not accept the given subject type	Funds and velocity domains (e.g. `CUSTOMER` passed to a funds call, `ORGANIZATION` to a velocity call)
`CARD_INVALID`	Card invalid	Most card-domain endpoints
`CARD_NOT_DEDICATED`	Not a dedicated-balance card	Opening a VA
`UNSUPPORTED_CURRENCY`	Currency not supported	Opening a VA, funds domain, balance alerts, effective-quota query
`PCI_NOT_CERTIFIED`	No sensitive-card-data entitlement	Retrieving sensitive card data
