HTTP status codes

Learn how to handle HTTP responses.

After submitting an API call to Adyen, you receive a response back to inform you that your request was received and processed. Depending on the HTTP status code of the response, you can build some logic to handle any errors.

HTTP responses

HTTP status code	HTTP status message	Description
200	OK	Request processed normally. The request message was successfully processed and produced a response. The response message varies, depending on the request method and the requested data.
201	Created	The request was successful and a new resource was created.
202	Accepted	The request was accepted, but has not been processed yet. This is not a guarantee that the request will be completed.
204	No Content	The server successfully fulfilled the request, and there is no additional content to send in the response.
301	Moved Permanently	The resource you requested moved to a different location.
400	Bad Request	Problem reading or understanding request. The receiving server cannot understand the request because of malformed syntax. Do not repeat the request without first modifying it. Check the request for errors, fix them, and then retry the request.
401	Unauthorized	Authentication required. You need to provide valid authentication credentials (username/password) to access the resource.
403	Forbidden	Insufficient permission to process request. You do not have the appropriate user rights to access the request. Do not repeat the request.
404	Not Found	File not found. The server could not retrieve the resource you requested at the specified location. It is possible that the resource becomes available in the future. Usually, this happens when the URL you pass with the request is incorrect. You can make subsequent calls.
405	Method Not Allowed	The target resource does not support this method.
406	Not Acceptable	The server could not produce an acceptable response.
408	Request Timeout	The server did not receive a complete request message within a certain amount of time. You can retry the request.
409	Conflict	Resource is locked. A conflict occurred because the request was already processed or is in progress. Identify the reason for the conflict and resolve it. You can retry the request if the API returns a transient error header with value true.
413	Payload too large	The body of your request was too large. The maximum request size is 10 MB. Send the request again with a size of less than 10 MB.
422	Unprocessable Entity	Request validation error. The request is well-formed (syntactically correct), but semantically incorrect: the receiving server can read the request, but cannot understand it.
429	Too Many Requests	You have sent too many requests in a short period. To handle this issue, implement a retry mechanism that uses exponential backoff with jitter.
500	Internal Server Error	Server could not process request. The receiving server encountered an unexpected condition that prevents it from fulfilling the request. You can also recieve a 500 status code when the request is incorrect, for example because of a missing or empty mandatory field.
501	Not Implemented	The server does not support the functionality required to complete the request.
504	Gateway Timeout	The server, acting as a gateway or proxy, did not get a response from the upstream server in time.

Handle 200 responses

An HTTP 200/OK response status code means that the request was submitted correctly and Adyen processed it successfully. An HTTP 200 response does not automatically mean that the payment or the modification request was successfully executed.

When the payment response includes a resultCode with a value of Refused or Error, a refusalReason field is added. Check the refusal reason messages to learn more about the possible issues of the payment or the modification request.

For example:

You send a capture payment request.
The response to your capture request returns HTTP 200/OK. This means:
- We received your request.
- We will execute a payment capture.
- We still do not know if the capture operation will be successful or not.
- We'll let you know in the corresponding webhook event.
If the capture operation fails, for example, because the acquirer declines to accept the shopper's card, the payable amount for the transaction is not collected.
Based on your settings, you'll receive a webhook message that includes the information about this capture example:
- The pspReference in this notification is the same as the pspReference in the capture modification response.
- The success field value is false, and the reason field includes a short message to explain the cause of the failure.

Handle 4xx and 5xx responses

In the following scenarios, the plataforma de pagamentos da Adyen does not accept or store submitted requests:

The request does not pass validation.
The request violates a security constraint.
The request violates a configuration constraint.
An internal error occurs on the plataforma de pagamentos da Adyen.

In these cases, you receive an error message with an error code containing a description of the problem.
In general, you should handle it as an exception.

There is no charge for rejected payment requests accompanied by an error message.

Debugging APIs

While building your integration into the Adyen APIs, you can reach out to us if you need additional help.

If you contact our Support Team, provide the pspReference returned in the header of the API response. The pspReference is a unique ID for that specific API request, and can be used by our Support Team to identify specific API calls.

Error response fields

In case of an error, the response object contains the following fields:

Field	Type	Description
`status`	Integer	Returns the HTTP status code.
`errorCode`	String	Returns the Adyen code that is mapped to the error message.
`message`	String	Returns the message, a short explanation of the issue.
`errorType`	String	Returns the type of error that was encountered. Allowed error types: `internal` `validation` `security` `configuration`
`pspReference`	String	Returns the PSP reference associated with this error. If the `pspReference` is not present in the response body, check the HTTP headers of the response.

The following example shows a possible error response:

{
    "status" : 403,
    "errorCode" : "901",
    "message" : "Invalid Merchant Account",
    "errorType" : "security"
}
