# [ACME API](https://zerossl.com/documentation/acme "ZeroSSL Documentation") Error Codes

## Error Codes

Note  
The errors listed here are relevant for the EAB credentials endpoint, the ACME API itself ( [https://acme.zerossl.com/v2/DV90](https://acme.zerossl.com/v2/DV90)) has its own set of errors.

**Errors are responded in JSON just as in the normal ZeroSSL API:**

    "error": {
        "code": 2902,
        "type": "failed_creating_eab_account"
